[PMID: 32645371 DOI: 10.1016/j.urology.2020.06.041] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 06/21/2020] [Accepted: 06/24/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To demonstrate the feasibility and success of a robotic approach to reconstruction of ureterovesical anastomotic strictures in kidney transplants. MATERIALS AND METHODS Between November 2017 and December 2019, a total of 5 patients with transplant ureteral stricture were identified and treated with robot assisted laparoscopic repair. All patients were confirmed to have ureteral stricture with a preoperative antegrade nephrostogram through their nephrostomy tube and cystogram. The patients demographics, ureteral characteristics, type of procedure, and outcomes are reported. RESULTS All patients were diagnosed after evaluation for renal deterioration. The average age of the patients was 49 years old. The average stricture length was 2.5 cm, and the location was variable, though more commonly in the distal ureter. Three patients required a pyelo-vesicostomy, while 2 required a ureteroneocystostomy. The mean length of stay was 2.2 days. Average follow-up was 97 days, with all 5 patients having successful outcomes, no strictures or delayed leaks were identified. There were no wound infections or readmissions within 30 days. CONCLUSION Though a complex repair, the robot-assisted approach to transplant ureter reconstruction using either an end to side neoureterocystotomy or direct pyelo-vesicotomy is technically feasible and successful. Given the many advantages inherent in comparison to an open approach, the robotic repair offers significant advantages to both the patient and the surgeon who is experienced with robotic surgery and reconstructive principles.

Abstract
No consensus exists about which ureterovesical anastomosis technique to use for kidney transplantation. The aim of this systematic review was to compare the existing techniques in relation to the risk of urological complications. All studies that compared ureterovesical anastomotic techniques in kidney transplantation were included. Study endpoints were urinary leakage, ureteral stricture, vesicoureteral reflux and hematuria. Subanalyses of stented and nonstented techniques were performed. Two randomized clinical trials and 24 observational studies were included. Meta-analyses were performed on the Lich-Gregoir (LG) versus Politano-Leadbetter (PL) techniques and LG versus U-stitch (U) techniques. Compared with the PL technique, the LG technique had a significantly lower prevalence of urinary leakage (risk ratio (RR): 0.47, 95% confidence interval (CI): 0.30 to 0.75) and a significantly lower prevalence of hematuria when compared with both PL and U techniques (RR: 0.28, 95% CI: 0.16 to 0.49 and RR: 0.23, 95% CI: 0.11 to 0.50, respectively), regardless of ureteral stenting. There was no difference in the prevalence of ureteral strictures or vesicoureteral reflux between the various techniques. Of the three most frequently used ureterovesical anastomotic techniques, the LG technique results in fewer urological complications than the PL and U techniques.

Abstract
OBJECTIVES To compare the mechanical and sutured ureteroneocystostomy in a canine model. METHODS In 18 dogs, extravesical ureteroneocystostomy on 1 side was randomly assigned to end-to-side anastomosis performed with a titanium ring-pin stapler or interrupted absorbable sutures. To create the antireflux tunnel, the longitudinal line of the muscle layer was closed over the implanted ureter with titanium clips or sutures. At 3 months postoperatively, renal ultrasonography, intravenous urography, ascending cystography, the Whitaker test, and the macroscopic and microscopic results were assessed. RESULTS The ureteroneocystostomy with the ring pin stapler and the antireflux tunnel construction with titanium clips had a 100% technical success rate. Compared with manual suturing anastomosis, the suture-free technique took a significantly shorter time and resulted in slightly, but not significantly, less ureteral obstruction after 3 months. One dog in group 2 had evidence of ureteral dilation and hydronephrosis compared with the normal contralateral side. No signs of stone formation, urinary cyst, or fistulas were found after either closure method. None of the 18 dogs demonstrated vesicoureteral reflux. Histologic examination showed no signs of acute inflammation or marked fibrosis in any of the 18 specimens. Moreover, the intrapelvic pressure in group 1 was approximately similar to that of the normal contralateral side. CONCLUSIONS Ureteroneocystostomy performed with a titanium ring-pin stapler is feasible and faster than using conventional sutures. This suture-free technique is simple and safe, with possibly lower complication rates than a nonstented suture technique. Additional studies with a longer follow-up duration are needed to confirm these results.

Abstract
The aim of the present study was to analyze the effects of ureteral stents used in renal transplantation on urologic as well as other complications. Cases of renal transplants from living or deceased donors performed in our hospital were retrospectively evaluated. The effects of the routine use of ureteral stents on postoperative complications were investigated. All outcomes and complications encountered during the postoperative follow-up were recorded. The Lich-Gregoire technique, which is a method of extravesical ureteroneocystostomy, was performed on all patients. One hundred and twenty-two patients underwent renal transplantation between 2001 and 2007 in our hospital. Stents were placed routinely in all patients. Leakage was observed in one patient, and one patient developed an obstruction; however, none of the patients developed an infection. A lymphocele developed in one patient. All urologic complications were treated without major morbidity. Graft loss did not occur. Complications following urinary anastomosis have a high rate of morbidity in renal transplantation. Ureteral stenting in renal transplant recipients prevents early urologic complications. The data generated in the current study were compared to the literature.

Abstract
Urologic complications, observed since the beginning of renal transplantation, cause significant morbidity and mortality. In the first few years the procedure was performed, incidence of urologic complications was reported to be 10% to 25%. Recently, the incidence of urologic complications after renal transplantation has decreased to 2.5% to 12.5%; unfortunately, a higher incidence exists in pediatric recipients, reaching approximately 20% with an associated 58% and 74% graft survival rates for cadaveric and living-related transplantation, respectively. We retrospectively analyzed the postoperative urologic complications reported in the medical charts of 1523 consecutive kidney transplantations (1130 men, 74.2%; 393 women, 25.8%; mean age, 31.9 +/- 10.9 years; range, 7 to 64 years; 354 cadaveric, 23.2%; 1169 living, 76.8%) performed by our team since 1975. The first 321 procedures took place at Hacettepe University Hospital in Ankara, Turkey, and the remaining 1202 were performed at Baskent University Hospital in Ankara. Urologic complications occurred in 46 (3%) recipients. Twenty-three (1.5%) of these patients had urine leakage, 15 (1%) had urinary obstruction due to ureteral stricture, 6 (0.4%) had distal ureter necrosis, and 2 (0.1%) developed renal calculi in the late postoperative period. Twenty-four out of 46 required reoperation for urologic complications. The remaining 22 patients were treated conservatively in our interventional radiology department with excellent results. In conclusion, urologic complications will always occur in the posttransplant period. Early diagnosis by experienced personnel and use of interventional radiology can greatly reduce the need for surgical treatment.

Abstract
Routine splinting of the ureterocystostomy during renal transplantation lowers the urological complication rate but increases patient's morbidity. The number needed to treat to prevent one urological complication is high. The aim of this study was to identify risk factors, which can be used in the implementation of a selective splinting ureterocystostomy protocol. Retrospective analysis of 475 consecutive renal transplantations performed between January 1999 and December 2004. Donor, surgical-technical and recipient factors were assessed. Urological complications occurred in 62 (13%) patients. In 29 of these 62 patients (6.1%), only a temporary percutaneous nephrostomy catheter was necessary and in 33 (6.9%) surgical revision was required. Episodes of acute rejection and delayed graft function were identified as the only independent risk factors for a urological complication: odds ratio 2.62 [95% confidence interval: (CI) 1.38-4.97] and 2.22 (95% CI: 1.14-4.33), respectively. None of the risk factors for urological complications after renal transplantation that are known at the time of performing the ureterocystostomy are useful for the implementation of a selective splinting protocol.

Abstract
Stenting of the extravesical ureteroneocystostomy in renal transplantation is controversial. This study is a metaanalysis of 49 published studies over 30 years time in which the extravesical technique was used. Stented and nonstented anastomoses were compared. One-hundred six articles published between 1973 and 2002 were reviewed and 49 met criteria for inclusion. Articles were required to list original, numeric, previously unpublished data and to report or to describe the use of an extravesical ureteroneocystostomy, with or without stent. Data were analyzed within separate groups, (1) randomized, controlled trials and (2) case series. Data were included from five randomized, controlled trials and 44 case series. In the controlled trials group, there were urologic complications in 6 of 407 stented (1.5%), and 35 of 389 nonstented subjects (9.0%) (p < 0.0001, OR 0.24, 95% CI 0.10-0.57). In the case-series group, there were urologic complications in 137 of 4245 stented (3.2%) and 433 of 9077 nonstented subjects (4.8%) (p = 0.007, OR 0.58, 95% CI 0.39-0.86). Renal transplants with stented extravesical ureteroneocystostomy have a significantly lower urologic complication rate than those with nonstented anastomoses. All five randomized, controlled trials individually found stented anastomoses to have a lower complication rate and this was confirmed by metaanalysis of these trials and of case-series data.

Abstract
We report the complication rate based on one urologist's experience over a 9-year period including over 1000 ureteral reimplants performed at the time of kidney transplantation. Among 1083 ureteral reimplant operations, there was a 4.3% urologic complication rate, including a 2.7% ureteral stricture rate and a less than 1% rate each of urine leak ureteropelvic junction obstruction, vesicoureteral reflux and clot obstruction. The factors that lead to a low urologic complication rate are believed to be the use of short ureteral segment using the Lich (compared to the Politano-Leadbetter) technique and the routine use of indwelling stents. In addition, a consistency in results was attributed to one transplant urologist performing all ureteral reimplants and managing all urologic complications.

Abstract
The urological complications in the first consecutive 1,000 renal transplants at our transplant center are reported with a minimum followup of 12 months. The kidney was implanted in the iliac fossa in all cases and in all but 3 the ureter was inserted into the bladder with a Politano-Leadbetter technique. Overall, there were 71 primary complications in 68 patients (7.1%), which included 36 ureteral obstructions, 25 ureteral or bladder leaks (including ureteral necrosis), 7 bladder outflow obstructions, 2 ureteral stones and 1 case of symptomatic vesicoureteral reflux. The use of high dose steroids in the early years was associated with a 10% urological complication rate, which decreased to 4% in patients receiving low dose steroids thereafter combined with azathioprine or cyclosporine. The urological complication was corrected after 1 procedure in 65 cases and after 2 procedures in 4. No grafts were lost due to urological complications. Two patients died, 1 of sepsis following transurethral resection of the prostate and subsequent ureteral necrosis, and 1 of hemorrhage following nephrostomy tube insertion. Most ureteral complications were treated by an open operation, although in recent years endoscopic techniques have become more common. Meticulous retrieval technique, low dose steroid protocols and rapid diagnosis are the crucial factors associated with a minimal incidence of urological complications after renal transplantation.

Abstract
The urological complications of 320 consecutive renal transplants performed at our institution between October 17, 1985 and November 10, 1989 are reviewed. The Leadbetter-Politano technique of ureteroneocystostomy was used in the first 160 patients (group 1) and an anterior extravesical technique modified from the methods of Witzel, Sampson and Lich was performed in the second 160 patients (group 2). Urological complications occurred in 15 patients (9.4%) in group 1 and 6 (3.7%) in group 2 (p = 0.04). Ureterovesical junction obstruction occurred in 6 patients (3.7%) in group 1 and 1 (0.6%) in group 2 (p = 0.05). Complications of leakage, ureteral necrosis and ureteral stricture were comparable in the 2 groups. Therefore, we advocate the use of the anterior extravesical technique over Leadbetter-Politano ureteral reimplantation based on the lower incidence of urological complications and various technical advantages, including less operative time, avoidance of a separate cystotomy, less hematuria and ability to use short donor ureters.

Abstract
From October 1970 to January 1986, 808 patients underwent renal transplant ureteroneocystostomy by an extravesical technique. Complications related to the anastomosis and/or ureter were reviewed. There were 23 total complications, for an over-all urological complication rate of 2.8 per cent. Of these complications 17 were related to the ureteroneocystostomy, for an anastomotic complication rate of 2.1 per cent. Complications were almost universally repaired by another operation. Two patients died and 1 lost the allograft because of urological complications.

Abstract
The surgical aspects of renal transplantation have now been studied thoroughly. Yet, technical complications are still common. This review may seem too complex, but proper attention to many small details means the difference between success and failure, or at least between large and small morbidity. Reduction of genitourinary complications is due to many innovations. The external ureteroneocystostomy is a primary method of urinary reconstruction which is simpler and produces fewer complications than the alternative procedures. Further, the complications that do occur are more easily and promptly treated. The end-to-side ureteroureterostomy, as currently performed, provides a ready secondary method of reconstruction if the primary method fails. The early exploration and operative correction of genitourinary complications substantially reduces long-term morbidity and mortality.

Abstract
Interventional radiologic procedures have become an important adjunct to the management of the renal transplant patient. Numerous problems can be dealt with, and in our experience these have included the diagnosis and treatment of ureteric obstruction, dilatation of renal artery stenoses, drainage of abscesses, hematomas and lymphoceles, management of complications of pancreatitis and treatment of bleeding due to fistulas and pseudoaneurysms.

Abstract
The urologic complications of 184 consecutive renal transplants (68 living-related and 116 cadaveric) performed at Walter Reed Army Medical Center are reviewed. An anterior extravesical technique modified from Witzel, Sampson, and Lich was used to reimplant the ureter. Urologic complications occurred in 11 patients (6%): urine leak (4), obstruction (3), stricture (3), and total ureteral necrosis (1). These complications occurred in the first 115 patients; no complications have been documented in the last 69 patients. The several advantages of extravesical ureteroneocystostomy include: less operative time, avoidance of a separate cystotomy, virtually no hematuria, ability to use short ureters, no need for splints or stents, shortened Foley catheter drainage, and no interference with native ureteral function. Complications are few and become uncommon with practice.

Abstract
Ureteroneocystostomy was used as the primary method of urinary tract reconstruction in 282 allograft renal transplants at our center since 1965. A nonrefluxing anastomosis was incorporated whenever possible. Seven patients who suffered major urological complications involving the ureteroneocystostomy required pyeloureterostomy as the method of repair using the patient's distal native ureter. No ipsilateral nephrectomy was performed and simple ligation of the native ureter with nonabsorbable suture was accomplished. Of the 7 patients 3 suffered hydronephrosis of the native kidney. None of these patients had signs or symptoms secondary to acute and chronic ureteral occlusion. Our experience suggests that intentional ligation of the native ureter during pyeloureterostomy does not result in increased morbidity to the transplant patient, and that the need for ipsilateral nephrectomy with its own added morbidity may not be necessary.

Abstract
The outcome of kidney transplantation depends on several factors. The quality of the ureter of the transplanted kidney and the technique of its connection with the recipient's urinary tract seem to be two of the most important ones. In this paper the authors analyse the incidence of ureteral complications of the grafted kidney in 99 ureterocystoneostomies performed in conjunction with kidney transplantation. Urinary fistulas occurred in 7, stenosis of the ureter in 3 cases. The diagnostic possibilities and treatment of the complications are discussed.

Abstract
Pyeloureterostomy was used as the preferred method of urinary tract reconstruction in 260 of 371 consecutive renal allograft procedures performed between September 1967 and December 1980. Initially chromic catgut suture was used for the anastomosis in 96 patients with ten complications developing (10.4%). Because of the high incidence of anastomotic leakage (8.3%) with chromic catgut suture, the next 101 pyeloureterostomies were constructed using 7-0 Tevdek. Although urinary leakage occurred in only five of these patients (4.9%), late stone formation occurred along the suture material in three patients (2.9%), influencing the conversion to 7-0 Prolene for this anastomosis. With this suture material, only two complications have occurred in 63 subsequent pyeloureterostomies (3.1%), neither related to the anastomosis. In comparison, eight complications developed in 111 patients who underwent reconstruction with the Politano-Leadbetter method of ureteroneocystostomy (7.2%). The currently recommended method for pyeloureterostomy, as described, when combined with meticulous attention to technical details has made pyeloureterostomy a safe and effective method of urinary tract reconstruction in renal transplant recipients, with morbidity indistinguishable from that of ureteroneocystostomy.

Abstract
The use of temporary diverting nephrostomy drainage in the management of immunosuppressed renal transplant patients with supravesical urinary extravasation, fistulas or ureteral obstruction is reviewed. In a literature survey covering an 11-year interval and 4,307 transplants there were 204 cases (4.7 per cent) of ureteral extravasation or fistula and 113 cases (2.6 per cent) of ureteral obstruction. Attempts at urologic repair in these 317 cases resulted in 30.9 per cent failure rate (98 cases), of which 86.7 per cent (85 cases) occurred in patients without nephrostomy compared to 13.3 per cent (13 cases) in patients with nephrostomy. In our 255 consecutive renal transplant patients there were 7 (2.7 per cent) with ureteral extravasation or fistula and 14 (5.5 per cent) with ureteral obstruction. Temporary nephrostomy was done in all 21 patients to protect the urologic repair and, when necessary, to control sepsis and allow for patient stabilization before delayed urinary tract reconstruction. In our series there was no mortality and only 1 renal unit (4.7 per cent) was lost as a consequence of urologic complications. The use of nephrostomy in transplant patients with ureteral extravasation, fistulas or ureteral obstruction is encouraged strongly to optimize patient and renal unit survival.

Abstract
Althrough rejection remains the most frequent cause of renal allograft failure, technical problems have contributed and continue to contribute to graft loss. Urologic complications may be caused by technical errors in the donor nephrectomy or in urinary tract reconstruction. During the past decade, however, with advances in medical and surgical management, the reported incidence of urologic complications in renal transplantation has declined steadily. This may be due to (1) more extensive donor and recipient preparation and evaluation for surgery, (2) improvement of surgical technique with increasing experience in donor and recipient, and (3) more refined diagnosis and treatment of urologic and infectious complications.

Abstract
The outcome of renal transplantation was examined in 52 pediatric patients (mean age 13 years) whose primary renal disease was obstructive uropathy. The bladder was used at transplantation in 45 allograft recipients, 39 of whom had had a previous lower urinary tract operation or bladder defunctionalization. An ileal loop was used in 7 recipients. The 52 patients received 73 renal allografts from 58 cadaver and 15 live-related donors. Presently, 40 patients (77 per cent) have functioning allografts, 4 have returned to dialysis and 8 (15 per cent) have died. The results indicate that the outcome of renal transplantation in patients with obstructive uropathy is similar to that of other transplant recipients. Damaged and defunctionalized bladders may be used successfully in most cases. If necessary an ileal conduit is an effective alternative. Post-transplant urologic complications occur with increased frequency but with appropriate management allograft salvage and patient survival are excellent.

Abstract
Ureteral complications occurred in 23 cases after 225 renal transplantations. The complications consisted of 17 urinary fistulas and 6 stenoses of the ureter. Fourteen of the urinary fistulas were successfully treated by conservative management. Two transplants were lost secondary to operation because of ureteral obstruction. Factors contributing to ureteral leakage were the technique of ureteral anastomosis, the handling of the donor ureter during donor nephrectomy and possibly ureteral necrosis by rejection crises. Ureteral stenosis and rejection crisis may have the same symptoms. Urinary fistulas can easily be observed by the urine extravasation. The treatment of urinary fistulas can be managed only by replacing the suprapubical drainage. The stenosis of ureter with subsequent deterioration of graft function needs an operation with the danger of loss of the transplanted kidney.

Abstract
Review of a consecutive series of 85 cadaveric renal transplants revealed urinary fistulas in 7 cases. Bladder fistulas originated from the anterior cystostomy suture line in 3 patients and required secondary closure in every case. Ureteral fistulas from the donor ureter often required a multistaged operation. In every case the end result has been satisfactory, with closure of the fistula and preservation of renal function.

Abstract
The first reported case of rupture of the renal pelvis associated with transplantation is presented. The obstruction was in the ureteral tunnel of the hypertrophic bladder. The cause of the weakness in the pelvic wall could not be determined. Differential diagnosis was acute rejection and lymphocele. Excretory urography was diagnostic. Treatment included revision of the ureteroneocystostomy with repair of the defect and internal stenting. Postoperative morbidity was minimal and satisfactory graft function was maintained.

Abstract
Transplantation is now an acceptable mode of therapy for end stage renal disease. Increased survival rates and acceptance of older recipients have resulted in an increased frequency of outlet obstruction in the male recipient. Reviews of urological complications in renal allotraansplantation have failed to emphasize this clinical entity. We present 3 patients, each emphasizing a different facet in the natural history of outlet obstruction in the male recipient of a renal allotransplant. The rationale for aggressive investigation of outlet obstruction is emphasized.

Abstract
Complete thrombosis of the infrarenal vena cava and the entire iliac venous system is a unique circumstance in a candidate for renal allotransplantation. This condition was created in a patient by the previous use of an inferior vena cava clip. The patient received a kidney transplant in the orthotopic intra-abdominal position, using his own renal vein for renovenous anastomosis. The usual method of urinary drainage was also modified. This approach to transplantation should be considered in the presence of partial clotting or occlusion in the distal vena cava or iliac venous system.

Abstract
Urinary fistulas developed in 13 of 134 patients after renal transplantation. Bladder fistulas originating from the anterior suture line in 6 patients were satisfactorily managed by urethral or paravesical drainage. Fistulas arising from the donor ureter were best treated by surgical repair using the recipient's own ureter. Caliceal fistulas in 3 patients were successfully treated with nephrostomy drainage. A favorable outcome was achieved in 11 of the 13 patients, with closure of the fistula and preservation of renal function.

Abstract
From 1963 to July 26, 1974, 211 men underwent renal transplantation at our clinic. Urethral strictures were present prior to the initial transplant in 4 patients (1.8 per cent) and developed in the post-transplant period in 13 patients (6.1 per cent). Postoperative bladder neck contractures occurred in 2 patients (0.9 per cent). Repeated urethral dilations and surgical procedures on the lower urinary tract were generally well tolerated. Infectious problems were the most common secondary complications. No patient or allograft was lost as a direct result of the lower tract obstruction or its treatment. The greatest morbidity occurred in those patients who had a combination of urethral stricture and/or bladder neck contracture, uremia, previous or current immunosuppression and the absence of urine flowing through the urinary tract. This combination occurred most often in the patient who experienced failure of the first allograft and was being prepared for a second or third transplant. To avoid potentially serious urologic complications, male patients should have a repeat lower urinary tract evaluation and definitive correction of existing obstruction before re-transplantation is considered.
