Chronic hepatic patients Essay


Aim of the work: to measure consequences of ureteroscopic direction of distal ureteral concretion in hepatic compromized patients and to standarize steps that taken to better the results and minimise morbidity.

Patients and methods: it was a prospective survey concerned with hepatic compromized patients and distal ureteral rocks subjected to ureteroscopic direction. The patients divided into 2 groups before and after building of multispeacility squad. The standard technique of ureteroscopy was performed under anethesia.

Consequences: Average age of 74 patients was 40 & A ; plusmn ; 3.7. Causes of hepatic inadequacy were bilharzial periportal fibrosis in 25 and cirrhosis in 49 patients. No aborted processs due to hemodynamic instability. Direct debut of the ureteroscope into the ureter without dilation in 56 patients. Mean operative clip was 44.1 & A ; plusmn ; 16.2 min. Seventen patients were discharged on the following twenty-four hours and the other patients ranged form 2-9 yearss. Simple rock extraction in 30 patients and after lithotripsy in 34 patients.The overall rock free rate was 86.5 % , 63.6 % in group I while 96.2 % in group II. The overall complications were 17.6 % , 9.5 % operative and 8.1 % posoperative one.

Preoperative hospitalization was performed for 50 patients in group II. The average preoperative hospitalization period was 1.6 & A ; plusmn ; 0.4 yearss. Recombinent factor VII was given for 2 patients, thrombocytes 3, desmopressin in 3 and Vitamin K in 7 patients, packed RBCs for 5 and 8 patients received albumin extracts preoperatively. Besides, postoperative transfusion of jammed RBCs, albumen and FFP for readmitted 2 patients.

Conculsion: Ureteroscopic intercession has been considered ideal minimally invasive process for direction of distal ureteral concretion. Hepatic inadequacy is debatable wellness status due to fragilty of patients, unnatural metabolic tracts and high leaning for urolithiasis. It is hard to measure in vivo haemostasis and reversibilty of coagulopathy in this patient population even with normal curdling profiles as a consequence of concealed unkown parametric quantities. Hence, preoperative medical rating and selective hospitalization for supportive steps and preoperative ureteral stenting is compulsory. We hope for more advancs in engineering and standarization of protocols for early diagnosing and direction of hepatic patients as thier prevalence is increasing.


Egypt is an endemic country for liver diseases due to the high prevalance of schistosomiasis and hepatitits ( up to 20 % ) with attendant hepatic periportal fibrosis and hepatic cirhosis. Hepatic inadequacy is a great medical job for the patients and their physicions. As the patients are in an increased hazard for development of urinary Ca oxalat concretions due to combination of multiple hazard factors. The metabolic hazard factors for urolithiasis are hyperoxaluria, malnutrition, acidosis, intravascular volume depletion and hapless physical public presentation.

Sometimes the urologist may be consulted for hepatic patients with urolithiasis and in demand for determination. The determination pick of conservative, surgery, SWL or minimally invasive endourological process is controlled by hypoalbuminmia, shed blooding diathesis, need for transfusion and immuncompromized province.

Patients with decompansated liver has disturbed certain physiological mechanisms ensuing in malnutrition, chronic anaemia, ascites, volum overload but they have intravascular depletion. Besides, hepatic inadequacy has bad impacts on styptic mechanisms through improper nutritionary factors soaking up, disturbs extrinsic curdling cascade, thrombopenia and thrombocyte disfunction, coagulating factors lack, fibrinolysis and dysfibrinogenemia.

Based on this background, on handling this brickle patient population, it is expected that turning away of black surgical results can be hard. In this survey we aim to measure consequences of ureteroscopic direction of distal ureteral concretion in hepatic compromized patients and to standarize safeguards that taken to better the results and minimise morbidity.

Patients and methods:

It was a retrospective designed survey concerned with patients had distal ureteral concretion and attendant hepatic inadequacy at a period of 10 old ages from January 1999 to December 2009. The medical studies of 974 patients were analyzed for preoperative, intraoperative and postoperative inside informations. The protocol of preoperative rating included full history pickings, complete physical scrutiny and labroatory probes such as uranalysis, civilization and sensitiveness trial, serum creatinine, fasting and postprandial blood sugar, complete blood image, liver map trials and curdling profile including PT, PTT and INR were performed. Morever, imaging trials such as apparent X ray of urinary piece of land ( PUT ) , abdominopelvic echography and computarized imaging. A new PUT was done instantly preoperatively and postoperatively, preoperative PUT to place the last rock site and postoperative one to set up a rock free position.

The criterion technique of ureteroscopy was performed in our section. Routine stiff cystoscope was used for meticolous visual image of the urethra and urinary vesica. The flexible-tipped guidwire passed into ureteric opening and advanced gently beyond the rocks to nephritic pelvic girdles. The intramural ureter was dilated utilizing balloon dilator under fluorscopic and/or ureteroscopic counsel. The ureteroscope was passed under direct vision over or alongside the guidwire. If an wedged rock prevent transition of floppy tipped wire, a combination of open-ended ureteric catheters with consecutive or angle-tipped hydrophilic wires normally used to short-circuit the rock. Once the rock is visualized a determination is made for the best method of extraction depending on different factors such as size, figure, grade of guess, grade of impaction and status of distal ureter. Our methods of pick for under vision extraction were alligator forceps, wire-prong forceps or rock basket. For larger or tightly impacted rocks, intracorporeal rock decomposition was performed by pneumatic and optical maser lithotripsy. At the terminal of the process, retrograde pyelography was performed to document absence of ureteral hurt and arrangement of 5 or 6 F external ureteric catheters or DJ catherters. Success was considered if the rock wholly extracted and no demand for farther processs.

From January 2001, we have adopted a multispeaciality squad attack composed of advisers of hepatology, urogenital medicine and anaesthesia. Patients were divided into 2 groups before and after building of mltispeciality squad. The purpose of this squad is initial rating and treatment of the medical position of each patient from different facets and introduces a intervention plane to restrict morbidity in this patient population. Besides, the squad gives advice for selective preoperative hospitalization for at least one twenty-four hours for appraisal and to command any defect in homeostasis such as terrible coagulapthy, terrible anemia, hypoalbuminemia and important ascites. In suspected patients with terrible coagulopathy, markers of curdling and haemostasis activation ( MOCHA ) were perfprmed in add-on to CBC and curdling profile. MOCHA evaluates anti-thrombin III and PT 1.5 atomization before and after factor VII intervention. Management of terrible coagulopathy composed of recombinant factor VIIa entirely or in combination with thrombocytes, desmopressin ethanoate, vitamin K and FFP harmonizing to badness and aetiology of coagulopathy. Preoperative packed ruddy blood cell transfused for hospitalized patients with terrible anaemia. Besides, salt free human albumen adminstrated for patient with important ascites and hypoalbuminemia. All admitted patients were started on preoperative contraceptive endovenous antibiotics. Routinely, ureteral stents were placed before ureteroscopy for acure obstructor and in big rocks,

The patient ‘s demographics, patient ‘s medical position, indicants for intercession, success rate, mechanism of calculus extraction, chemical rock analysis, process clip, outcomes, hospitalization clip, hepatic map trials, intraoperative and postoperative complications were collected, tabulated and statistically analyzed. Statistical analysis was performed utilizing the Statistical Package for the Social Sciences, version 10 ( SPSS ) .


A sum of 974 patients underwent ureteroscopic direction of distal ureteral concretion and had important hepatic inadequacy. Their age ranged from 32 to 65 old ages ( intend & amp ; plusmn ; SD ; 40 & A ; plusmn ; 3.7 ) , 650 patients were males. One 1000 and four nephritic units were operated, 511 patients were kicking on Rt side, 433 on Lt side and 30 on both sides.

The patients? features and indicants for direction are shown in table 1. Severe gripes or hurting was the chief presenting symptom in 25 patients, upper piece of land obstructor in 16, recurrent UTIs in 13, microscopic haematuria in 10, bladder crossness in 7 and deficiency of rock patterned advance in 3 patients. The average ureteral rock length was 8.4 & A ; plusmn ; 2.1 ( run 6.1-14 millimeter ) . Fifty five patients presented with primary rock disease while 19 patients presented with recurrent rock disease after ureterolithotomy ( 5 patients ) , SWL ( 5 patients ) and ureteroscopic use of rocks ( 9 patients ) . The most common causes of hepatic inadequacy in our patients population were periportal fibrosis in 25, hepatitis C in 16, hepatitis B in 11, hepatitis A in 9, intoxicant and drug maltreatment in 5, bilious and cryptogenic cirrhosis in 3, autoimmune cirrhosis in 1 or a combinaton of these causes. Our patients had at least one extra medical disease including diabetes mellitus in 27, terrible anaemia in 22, high blood pressure in 15 and cerebrovascular disease in 12 patients.

The operative and postoperative informations are illustrated in table 2. All endurological processs were performed under anaesthetic Sessionss. No aborted processs due to hemodynamic instability. The ureteric opening was dilated in 15 patients ( 20.4 % ) . Direct debut of the ureteroscope into the ureter without dilation in 56 patients ( 75.7 % ) due to utilize of little semirigid ureteroscope in 17 patients and preoperative ureteral stenting of the others. Failed dilation in 3 patients. Mean operative clip was 44.1 & A ; plusmn ; 16.2 ( scope ; 32-140 ) min. Mean fluoroscopy clip exposure was 3.2 & A ; plusmn ; 1.1 min. At the terminal of the process, a double-pigtail ureteric stent was placed in the ureter after 50 processs and ureteric catheter was positioned into the nephritic pelvic girdle in 22 processs. The pick of stent type depends on endoscopist experience and rating, rock load ( size and figure ) , use clip and operative complications. The average postoperative stent period was 10.3 & A ; plusmn ; 1.7 ( scope ; 3-28 ) yearss while the external ureteric catheter was removed after 1-2 yearss.

Merely 17 patients ( 23 % ) were healthy and discharged on the following twenty-four hours. The staying 57 patients were hospitalized for 2-9 yearss ( average ; 2.1 & A ; plusmn ; 1.4 ) . The successful endoscopic manuvres included simple rock extraction with hold oning forceps or basket in 30 patients and usage of intracorporeal pneumatic or optical maser lithotripsy in 34 patients followed or non by rock fragments removal with forceps or basket after lithotripsy.

The overall rock free rate for 74 patients was 64 patients ( 86.5 % ) . The success rate of group I ( 14 out of 22 ) was 63.6 % while 96.2 % in group II ( 50 out of 52 ) . Whereas, the overall failure rate was 13.5 % . Eight patients failed in group I due to operative hemorrhage in 6 patients and ureteral hydrops with inability to go through guidwire in 2 patients. Besides, the failed 2 processs of group II were due to false transition and inability to distend tight lower terminal bilharzial stenosis ureter. DJ stenting was performed for all failed instances except 2 patients with failed transition of guidwire from the start. Rigorous observation was done for 2 patients and passed without complications. The average followup was 6 months ( scope ; 1-12 ) . The recorded operative complications were ureteral hemorrhage in 6 patients and false transition in 1 patient while postoperative complications in the signifier of haematuria in 2 patients, fever in 2 patients and flank hurting in 2 patients.

Preoperative hospitalization was performed from the begining of the 2nd twelvemonth of the survey. Forty seven out of 52 patients were hospitalized in from group II while merely one patient from group I. The average preoperative hospitalization period was 1.6 & A ; plusmn ; 0.4 yearss ( scope ; 1-7 ) . Recombinent factor VII was given for 2 patients. Besides thrombocytes were given in 3 patients, desmopressin ethanoate in 3 and Vitamin K in 7 patients. Five patients received jammed RBCs and 8 patients received albumin extracts preoperatively. Besides, postoperative transfusion of 2 units of jammed RBCs in add-on to albumin and FFP for readmitted 2 patients with hemorrhage and UTIs for 2 yearss.

Rock analysis was obtained for 45 patients, the analysis consequences revealed 27 pure or assorted Ca oxalate, uric acid in 10 and Ca phosphate in 8 specimens.

Multivariate arrested development analysis, showed that failure rate extremely associated with same

The prevalence and impact of different variables with hazard factors in chronic hepatic patients with ureteroscopic intervention of urolithiasis such as. the concluding form for analysis of logistical arrested development showed that the variable strongly associated with the failure rate were


In the medical pattern, shed blooding diathesis and its implicit in pathology constitutes a great challenge to the experient urologist who should tailorate the mangement for every patient harmonizing to environing fortunes. Many literatures evaluate the efficaciousness, safety and morbidity of endourological direction of urolithiasis but a few discuss its impact on hepatic compromised patients group. Fortunately, high experience was gained in our establishment due to direction of many hepatic patients with urological diseases such as microscopic haematuria or diagnostic urolithiasis whatever their age, sex, aetiology, phase and agressivness of the disease. As our medical Centre located in Delta of Egypt, surrounded by rural endemic country with bilharzia and hepatitis. However, the incidence of hepatic patients decreased in last old ages due to governmental attempts with improved wellness services and instruction.

It was noted that patients with chronic liver disease are at increased hazard of perioperative hemorrhage after minor surgery or simple endourological manuvre compared with healthy persons. These delicate patients group are in demand for drawn-out hospitalization with multiple medicines and blood transfusion. Traditionally, preoperative standardization of the correctable parametric quantities is compulsory to safe patient ‘s wellness, life and minimizes the morbidity as possible. Besides, the disagreement between usage and arrest of decoagulants in chronic liver diseases addition hazard of extremes either shed blooding or thromboembolic onslaughts. To get the better of these medical facts, preoperative elected hospitalization is required to command any medical jobs and avoid unexpected surprise.

Shed blooding inclination in patients with chronic liver diseases was multifactorial in beginning due to thrombocytopenia, drawn-out curdling clip and hyperfibrinolysis. The traditional methods of hemorrhagic control are normally failed with possible hazard. So it is better to understand the pathophysiology of the disease to be able confronting it and diminish its morbidity. The methods of shed blooding control with hepatic patients include FFP, desmopressin, vitamin K and vitamin K dependent curdling factors. These steps have serious side effects such as declining portal force per unit area and disseminated vascular coagulopathy with attendant increasing strength and frequence of shed blooding onslaughts. Blood and FFP transfusions have a possible hazard of transmittal of blood borne infection. Recently, rFVIIa was used in in this patient group after its FDA blessing in 1999 for shed blooding upsets in haemophilia A or B with inhibitors to factor VII or IX. But its theoretical side effects are hypercoagulable province, thromboembolism and high costs. It was found that incidence of thromboemblsim after usage of 18.000 doses of rFVII was low ( 0.009 % ) . The consequences of group I and II

In the different literatures on the ueteroscopic intervention of ureteral concretion, utilizing a assortment of ureteroscopes and intracorporeal lithotripsy devices, revealed success rates of 86-100 % [ 14 ] , even in one phase bilateral ureteroscopy for bilateral ureteral rocks, it was found that the rock free rate was 92 % ( at least one side ) and 70 % ( bilateral sucess ) [ 15 ] . From these valuable researches, urologist should be adherent to certain safety factors to derive good consequences such as arrangement of safety guidwire and equal ureteric dilation from the start, halt if the rock non be visualized at any measure of backdown, no usage of undue force, presence of C-arm unit, usage of little semirigid and stiff endoscopes, attention about deriving experience and better larning curve. In our survey, the overall success rate was 86.5 % , 63.6 % in group I and 96.1 % in group II.The betterment of consequences in group II compared to group I is attributable to elective preoperative hospitalization, larning curve, accretion of experience with ureteroscopy, handiness of little stiff and semirigid ureteroscopes and pneumatic and optical maser lithotripters.

In the present survey, active dilation of the ureteric opening and intramural ureter was performed in 15 patients, direct ureteroscopic entree in 56 patients ( due to utilize of little stiff ureteroscope in 17 and inactive dilation in 39 patients in the preoperative hospitalization period ) and failed dilation for 3 patients. Causes of failed ureteral dilation included ureteric false transition and inability to go through guidwire due to edema. Besides, ureteral stenting was done for most of failed ureteroscopy ( 8 of 10 patients ) . In our experience, passive or active ureteric dilation allows for more rapid, less forceful entree, which is of import if multiple base on ballss of one or multiple ureteroscopes are necessary. Besides, dilation allows for easier extraction of larger or irregular rocks safely without fright of long-run sequelae after dilation [ 19 ] . Besides, arrangement of stent after failed effort is of import to let urinary drainage and inactive dilation of ureter for easier subsequent instrumentality [ 20, 21 ] .

Ureteral stents or catheters have been placed routinely after ureteroscopy to avoid partial urinary obstructor and wing hurting due to mucosal hydrops. For this ground, we perfer to infix external ureteric catheters for 1-2 yearss after unsophisticated consecutive forward ureteroscopy and to avoid cystoscopic remotion of stents taking in consideration the overall costs. Most processs ( 72 patients ) were completed by puting either ureteric catheter ( 29.7 % ) or DJ ureteric stent ( 67.6 % ) . The construct and consequences agree with that of Djaladat et Al [ 22 ] . Period of hospitalization is normally less if JJ stents were inserted but 2nd cystoscopic process under anaesthesia was needed for stent remotion. This job can be overcome by usage of stents with dangles or open-ended external ureteric catheters that removed easy without uncomfortableness and avoid costs of cystoscopic remotion of stent [ 11 ] .

While ureteroscopy has proved to be an effectual therapy in the intervention of ureteric concretion, it has greater possible for complications. In a reappraisal of early Mayo Clinic experience [ 23 ] , complications were reported in 20 % of patients, including febrility, failure to take the rock, ureteric hurt and stenosiss. Similarly, Stoller and Wolf [ 25 ] reported 314 ureteric perforations and 17 ureteric avulsion during 5117 processs. Harmon et al [ 26 ] reported lessening in overall complicatons from 20 % to 12 % while major ureteral hurts decreased from 6.6 % to 1.5 % in 10-year interval. Morever, Elashry et al [ 27 ] in a recent reterospective survey recorded that success rate improved from 85.7 % to 97.3 % and important lessening in intraoperative complications from 15.1 % to 4.1 % and postoperative complications from 16.1 % to 8 % within 15-year experience. The overall complications of our patients was 17.6 % , intraoperative complications ( 9.5 % ) such as hemorrhage and false transition while postoperative complications ( 8.1 % ) in the signifier of wing hurting, febrility and haematuria with UTIs. These complications were accepted and managed in outpatient cautiously except 2 readmitted patients.

Our consequences of bivariate and multivariate logestic arrested development analysis demonstrated that failure of the processs and complications are extremely associated with operative continuance, rock size, rock impaction, sawbones experience and type and size of ureteroscope when commanding other factors. These consequences are in coordination with that of Elashry et Al. [ 27 ] and added that sawbones experience and larning curve were important factors associated with reduced intraoperative complications from 9.4 to 3.1 % and increase stone free rate from 82 to 98 % . Besides, in survey of Hamida et Al on 50 patients ( 100 nephritic units ) , they determined that the prognostic factors of failure of ureteroscopy were stone diameter ( & gt ; 15 millimeter ) , rocks in the lumbar ureter and pronounced pit distension [ 15 ] .


Ureteroscopic intercession has been considered the standard ideal minimally invasive process for direction of distal ureteral concretion. Patients with hepatic inadequacy are hard debatable wellness status due to fragilty of patients, unnatural metabolic tracts and high leaning for urolithiasis. It is hard to measure in vivo haemostasis and reversibilty of coagulopathy in this patient population even with normal curdling profiles as a consequence of concealed unkown parametric quantities. Hence rigorous preoperative medical rating and selective hospitalization for supportive steps and preoperative ureteral stenting is compulsory under supervising of multispecialty squad. We hope for more advancs in engineering and standarization of protocols for early diagnosing and direction of hepatic patients as thier prevalence is increasing.
