Abstract
BACKGROUND Vesico-ureteral reflux (VUR) is considered to be a risk factor for recurrent febrile urinary tract infections and impaired renal transplant survival. METHODS An online survey supported by the European Society for Paediatric Nephrology was designed to evaluate current management strategies of VUR in native and transplanted kidneys of recipients aged <18 years. RESULTS Seventy-three pediatric transplant centers from 32 countries contributed to the survey. All centers performed urological evaluation prior to pediatric kidney transplantation (KTx) with subsequent interdisciplinary discussion. Screening for VUR in native kidneys (30% in all, 70% in selected patients) led to surgical intervention in 78% (11% in all, 89% in selected patients) with a decided preference of endoscopic intervention over ureterocystoneostomy. Following KTx, continuous antibiotic prophylaxis was applied in 65% of the patients and screening for allograft VUR performed in 93% of selected patients. The main management strategies of symptomatic allograft VUR were continuous antibiotic prophylaxis (83%) and surgical treatment (74%) (endoscopic intervention 55%, redo ureterocystoneostomy 26%). CONCLUSIONS This survey demonstrates the high variability in the management of VUR in pediatric KTx recipients, points to knowledge gaps, and might serve as a starting point for improving the care for patients with VUR in native and transplanted kidneys.

Urology 2022; 165:336-342. [PMID: 35065141 DOI: 10.1016/j.urology.2022.01.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Revised: 01/09/2022] [Accepted: 01/09/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To describe a stentless modified Lich-Gregoir technique (mLG) for ureteroneocystostomy in renal transplantation (RT), with early bladder catheter (BC) removal (under 48 hours), and compare the postoperative results with those of the traditional technique (LG) with routine bladder catheter removal (4 to 5 days). The modification consists of maintaining a thin layer of detrusor fibers covering the bladder mucosa during dissection, which is incorporated into the anastomosis to reinforce the ureteroneocystostomy. MATERIALS AND METHODS This retrospective cohort study compared the postoperative outcomes of 100 consecutive patients who underwent mLG with early removal of BC between October 2018 to November 2019 with those of a historical cohort of 165 consecutive patients transplanted using stentless LG and routine removal of BC, who underwent surgery between July 2017 and September 2018. All transplants were performed by the same surgeon. Follow-up was 6 months. RESULTS Demographic characteristics were comparable, although patients in the mLG group had a higher mean preoperative urine volume (911±753.8mL vs. 629±638.6mL, p=0.016). Patients in the mLG group successfully underwent early BC removal (2.2±0.9 vs. 4.8±4.8 days, p<0.001), with no differences in the incidence of surgical or clinical complications, including urine leaks (1 vs. 3%, p=0.284). In addition, mLG patients presented a shorter mean length of hospital stay (6.5±5.0 vs. 7.1±6.2 days, p=0.023). CONCLUSION This stentless modified Lich-Gregoir technique enables safe early bladder catheter removal and is associated with reduced hospital length of stay.

Abstract
Background The aim of this study was to evaluate the safety and feasibility of prophylactic ureteric stenting during kidney transplantation (KT). Methods The authors retrospectively reviewed patients who underwent KT between June 2016 and June 2019. The prophylactic ureteral stenting group (double-J [DJ]) and no-stent group (no-DJ) were compared with respect to the clinical data and surgical outcomes. Results A total of 42 patients underwent KT; 17 patients were classified into the DJ group and 25 patients into the no-DJ group. Antithymocyte globulin induction and donor-specific antibody positivity were significantly higher in the DJ group. There were no significant differences between the groups in terms of symptomatic urinary tract infection (UTI). The time to postoperative UTI was significantly shorter in the DJ group than in the no-DJ group (33.5±7.8 vs. 105.3±71.6 days, P=0.013). The development of postoperative BK viremia was significantly higher in the no-DJ group (0.0% vs. 16.0%, P=0.035). Urologic complications were significantly higher in the no-DJ group (0.0% vs. 16.0%, P=0.035). In the no-DJ group, urologic complications occurred in four patients ureteroneocystostomy stenosis in three patients and ureteroneocystostomy leakage in one patient. Percutaneous ureteral interventions were performed for all patients using percutaneous nephrostomy and reno-uretero-vesical stenting. However, there were no postoperative urologic complications in the DJ group. Conclusions Prophylactic ureteric stenting during KT may be safe and feasible without significantly increasing the incidence of UTI and BK viremia. Additionally, prophylactic ureteric stenting may reduce urologic complications after KT.

Abstract
BACKGROUND Although rare, major urologic complications (MUC) in kidney transplantation can cause significant morbidity, increased cost, and may even lead to graft loss. Ureteric stents are routinely used to prevent MUC, although complications related to their use have been reported. Here, we systematically reviewed the role of routine stenting in preventing MUC in kidney transplantation with extravesical ureteric implantation and performed a meta-analysis of 6 randomized controlled trials. METHODS A PubMed search was performed for studies on MUC and stents in kidney transplant recipients. Randomized controlled trials were shortlisted for the review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RevMan 5 was used for statistical analysis, and outcome analysis was done with Cochran-Mantel-Haenszel test using random effect model. RESULTS Six trials meeting the criteria were identified. Although stent use did not decrease the incidence of urinary leak (odds ratio [OR], 0.39; 95% CI, 0.14-1.11; P = .08) or obstruction (OR, 0.41; 95% CI, 0.13-1.24; P = .11), it was associated with a higher incidence of urinary tract infection (OR, 3.59; 95% CI, 1.33-9.75; P = .01). CONCLUSION In the present era of extravesical ureterovesical anastomosis, routine stenting has a limited role in decreasing major urologic complications and may be associated with higher incidence of urinary tract infections.

Abstract
Double-J (DJ) stents are used in urology practice for various reasons. In renal transplantation, DJ stenting is used to treat the complications like urine leak and ureteric obstruction. However, the role of routine or prophylactic DJ stenting during renal transplantation is debatable. Most of the urinary complications occurring following renal transplantation are because of poor surgical technique and transplant ureteric ischemia. Routine DJ stenting cannot be a substitute for sound surgical technique, which avoids ureteric devascularization and create watertight ureterovesical anastomosis. DJ stenting increases the risk for complications like recurrent urinary tract infection, stent encrustation, stone formation, hematuria, and severe storage lower urinary tract symptoms. Routine DJ stenting during renal transplantation is not mandatory. It can harm an immunosuppressed renal transplant recipient by predisposing to various complications.

Abstract
Background Ureteral stents are successful in reducing urological complications after renal transplantation. However, the optimal duration and method of stenting have not yet been clarified. The objective of the present study was to investigate the frequency of urological complications when a 5-day external stented ureterocystostomy protocol was followed. Methods A single-center nonrandomized analysis of 392 kidney transplantations between June 2003 and June 2007 was conducted. From July 2005 all 196 renal transplant recipients received a 5-day external stented ureterocystostomy. A urological complication was defined as any cause leading to the placement of a percutaneous nephrostomy catheter and/or surgical revision of the ureterocystostomy. Results In the non-stented group, 21 of the 196 patients (10.7%) developed a urological complication compared to 13 patients (6.6%) in the stented group (p = 0.151). In the stented group, 2 of the 66 recipients of a living donor transplant (3.0%) developed a urological complication compared to 8 of the 59 recipients (13.6%) in the non-stented group (P = 0.030). Eleven of 130 recipients of a deceased donor transplant (8.5%) in the stented group developed a urological complication, compared to 13 of the 137 recipients (9.5%) in the non-stented group (P = 0.769). The surgical revision rate of the stented and the non-stented group was 5/13 39% and 6/21 29%, respectively. Conclusions A 5-day routine external stent protocol is efficacious in living donor renal transplantation in preventing early postoperative ureter obstruction, but this stenting period seems inadequate for deceased donor renal transplantation.

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
We retrospectively evaluated the use of double-j stent and the incidence of urological complications in 2 groups of patients who received a kidney transplant. From January 2005 to September 2007 we studied 172 patients receiving kidney transplants, 65 and 107 from living and cadaver donors, respectively. From the 172 patients, a total of 34 were excluded due to ureterostomy or Politano-Leadbetter ureterovesical anastomosis. Another 21 patients were excluded from the study due to graft loss due to acute or hyperacute rejection, cytomegalovirus (CMV) infection, or vascular complication. The remaining patients were divided into 2 groups: group A (44 patients) and B (73 patients) with versus without the use of a double-j-stent, respectively. The 2 groups were comparable in terms of donor and recipient gender, ischemia time, and delayed graft function. We failed to observes significant differences between the 2 groups in mean hospital stay (23 +/- 9 and 19 +/- 9), urinary leak (2.3% and 4.1%), and urinary tract infection (20.4% and 19.2%), among groups A and B, respectively. The only difference observed concerned the gravity of the urinary leak; no surgical intervention was needed among the double-j stent group versus 2 patients demanding ureterovesical reconstruction in the nonstent group. In conclusion, our data suggested that the routine use of a double-j stent for ureterovesical anastomosis neither significantly increased urinary tract infection rates, nor decreased the incidence of urinary leaks, but may decrease the gravity of the latter as evidenced by the need for surgical intervention.

Abstract
OBJECTIVES To evaluate the impact of the routine use of double-J stents in live-donor renal transplantation at a single institute from a prospective randomized study. METHODS A total of 100 patients were prospectively randomized into two groups of 50 patients each. Group 1 received a routine double-J silicone ureteral stent and group 2 did not. A standard Lich-Gregoir ureteroneocystostomy was performed in both groups. In group 1, the patients were scheduled for stent removal after 2 weeks. RESULTS Both groups were comparable in terms of age, sex, ischemia time, number of renal arteries, and time to diuresis. In group 1, two grafts were lost in the early postoperative period and those patients were excluded from the final analysis. None of our patients in either group had developed a ureteral stricture at a mean follow-up of 10.8 +/- 3.6 months. In the stented group, 2 patients developed a urinary leak, but no leakage was reported in the nonstented group (P = 0.14). Although 19 patients in group 1 (39.6%) had a urinary tract infection, only 9 in group 2 (18%) showed evidence of a positive urine culture (P = 0.02). The presence of a ureteral stent and female sex were the independent predictors of postoperative urinary tract infection on multivariate analysis. The mean serum creatinine at discharge was 1.2 +/- 0.3 mg% and 1.2 +/- 0.4 mg% in groups 1 and 2, respectively (P = 0.2). CONCLUSIONS The results of our study have shown that routine ureteral stent insertion has no impact on the rate of vesicoureteral leakage or obstruction in live-donor renal transplantation, whereas it is significantly associated with an increased incidence of urinary tract infection. Stenting should be limited to patients with a pathologic and/or defunctionalized bladder.

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
OBJECTIVE To determine the incidence of urological complications of renal transplantation at one institution, and relate this to donor and recipient factors. PATIENTS AND METHODS A consecutive series of 1535 renal transplants were audited, and a database of donor and recipient characteristics created for risk-factor analysis. An unstented Leadbetter-Politano anastomosis was the preferred method of ureteric reimplantation. RESULTS There were 45 urinary leaks, 54 primary ureteric obstructions, nine cases of ureteric calculi, three bladder stones and 19 cases of bladder outlet obstruction at some time after transplantation. The overall incidence of urological complications was 9.2%, with that for urinary leak or primary ureteric obstruction being 6.5%. One graft was lost because of complications, and there were three deaths associated directly or indirectly with urological complications. There was no association with recipient age, cadaveric vs living-donor transplants, or cold ischaemic times before organ reimplantation, although the donor age was slightly higher in cases of urinary leak. There was no association with kidneys imported via the UK national organ-sharing scheme vs the use of local kidneys. The management of these complications is discussed. CONCLUSION The incidence of urological complications in this series has remained essentially unchanged for 20 years. The causes of these complications and techniques for their prevention are discussed.

Abstract
BACKGROUND Whether routine ureteric stenting in low-urological-risk patients reduces the risk of urological complications in kidney transplantation is not established. METHODS Eligible patients were recipients of single-organ renal transplants with normal lower urinary tracts. Patients were randomized intraoperatively to receive either routine stenting or stenting only in the event of technical difficulties with the anastomosis. All patients underwent Lich-Gregoire ureteroneocystostomy. RESULTS Between June 1994 and December 1997, 331 kidney transplants were performed at a single center, 305 patients were eligible, and 280 patients were enrolled and randomized. Donor and recipient age, sex, donor source, whether first or subsequent grafts, ureteric length, native renal disease, and immunosuppression were similar in each group. In the no-routine-stenting group 6 of 137 patients (4.4%) received stents after randomization for intraoperative events that in the surgeon's opinion required use of a stent. In an intention-to-treat analysis there was no difference between groups in the primary outcome cluster of obstruction or leak [routine stenting 5 of 143 (3.5%) vs. no routine stenting 9 of 137 (6.6%); P=0.23], or in either of these complications analyzed separately. All urological complications were successfully managed without major morbidity. Living donor organs and shorter ureteric length (after trimming) were univariate risk factors for leaks, although increasing donor age was associated with obstruction. CONCLUSIONS Routine ureteric stenting is unnecessary in kidney transplantation in patients at low risk for urological complications. Careful surgical technique with selective stenting of problematic anastomoses yields similar results.
