Outcomes of Kidney Transplant Recipients With Percutaneous Ureteral Interventions: A Single-Center Study. Transplant Direct 2016; 3:e123. [PMID: 28349123 PMCID: PMC5361563 DOI: 10.1097/txd.0000000000000637] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2016] [Accepted: 10/02/2016] [Indexed: 01/21/2023] Open
Abstract
Background Long-term outcomes of kidney transplantation recipients with percutaneous ureteral management of transplant ureteral complications are not well characterized. Methods Electronic records of 1753 recipients of kidney-alone transplant between January 2000 and December 2008 were reviewed. One hundred thirty-one patients were identified to have undergone percutaneous ureteral management, with placement of percutaneous nephrostomy tube or additional intervention (nephroureteral stenting and/or balloon dilation). Indications for intervention included transplant ureteral stricture or ureteral leak. Kaplan-Meier survival curves and multivariable regression modeling were performed to determine survival outcomes. Results Kaplan- Meier graft survival (P = 0.04) was lower in patients with percutaneous ureteral intervention for transplant ureteral complication. Graft survival at 1, 5, and 10 years was 94.3% 78.3%, and 59.1% for no intervention and 97.2%, 72.1%, and 36.2% for intervention cohort. Patient survival (P = 0.69) was similar between cohorts. Multivariate analysis demonstrated no association with graft failure (hazard ratio, 1.21; 95% confidence interval, 0.67-2.19; P = 0.53) or patient death (hazard ratio, 0.56; 95% confidence interval, 0.22-1.41; P = 0.22) in intervention group. The major cause of graft failure was infection for percutaneous ureteral intervention group (20.4%) and chronic rejection for those without intervention (17.3%). Conclusions Kidney transplant recipients with percutaneous ureteral interventions for ureteral complications do not have a significant difference in graft and patient survival outcomes. Therefore, aggressive nonoperative management can be confidently pursued in the appropriate clinical setting.

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
We retrospectively studied the incidence of urological complications in a consecutive series of 590 patients (group B) who received a kidney transplant (KT) with a ureteral stent from January 1994 to December 2002. The ureteral stent was sewn to the bladder catheter during the surgical procedure and left in situ for a mean time of 10 days (range 8 to 12 days). The results were compared to a consecutive series of 414 patients who received a KT from March 1986 to December 1993 without a ureteral stent (group A). The two groups were comparable in terms of donor and recipient gender, ischemia time, delayed graft function, and chronic rejection incidence, but differed in mean donor age (44.1 vs 36.0 years), mean recipient age (45.4 vs 39.1 years), living/cadaveric donor rate (19.8% vs 11.9%), arterial lesions and bench reconstruction rate (11.1 vs 3.5%), as well as acute rejection episodes (11.7% vs 29.2%). Complications were seen in nine patients in group B (1.5%) and 17 patients in group A (4.1%) (P < .0001). Urinary leaks presented in two patients in group B (0.3%) and 11 patients in Group A (2.6%; P < .0001), while stenosis was present in six patients in group B (1.5%) and 7 in group A (1.2%) (P = NS). Urological complications such as urinary tract infection and macroscopic hematuria were similar in both groups. Time to presentation of a leak was within 2 weeks from KT in 10 patients (92.3%), while stenosis presented early in four patients (one in group B and four in group A). Of the stenoses, 69.3% presented late (beyond 12 weeks) in five patients in group B and three in Group A. In conclusion, our data suggest that routine use of double pigtail ureteral stent significantly decreased the incidence of leaks and early stenoses, but it did not modify late stenosis incidence. In the last decade, risk factors for urological complications have been increasing over time, namely, older donors and older recipients, living donation, length of dialysis, and the use of grafts with arterial lesions. Therefore we believe that a ureteral stent should be routinely considered to afford the advantage to protect the urinary anastomosis in the early postoperative period when the incidence of complications is highest, without the need of cystoscopy for its removal.

Abstract
OBJECTIVES To report our results after antegrade endoscopic treatment of ureteral stenosis with balloon dilation with or without holmium laser endoureterotomy. Ureteral stenosis is the most common long-term urologic complication of renal transplantation. METHODS From July 2000 to October 2002, 9 renal transplant patients with ureteral obstruction diagnosed by an increase in serum creatinine and radiologic evidence presented for endoscopic treatment. All patients were treated with nephrostomy tube drainage followed by antegrade flexible nephroureteroscopy and balloon dilation of the stricture. Three patients required holmium laser endoureterotomy during the same procedure because of fluoroscopic and endoscopic evidence of persistent stricture. All patients were treated with ureteral stents and nephrostomy tubes postoperatively. The median follow-up was 24 months (range 6 to 32). RESULTS The site of stenosis was at the ureterovesical anastomosis in all patients, and the mean stricture length was 0.28 cm. Two patients had previously undergone ureteroneocystostomy for prior ureteral stenosis. Six patients (66%) required only balloon dilation, and 3 patients (33%) also required holmium laser endoureterotomy. The median ureteral stent and nephrostomy tube duration was 40 and 62 days, respectively. The mean serum creatinine level was 2.3 mg/dL at presentation and 1.7 mg/dL at the last follow-up visit. After a median follow-up of 24 months, the ureteral patency and graft function rates were both 100%. No perioperative complications occurred. CONCLUSIONS Balloon dilation with or without holmium laser endoureterotomy was successful and safe in this group of renal transplant patients with short ureterovesical anastomotic strictures.

Abstract
PURPOSE To evaluate the efficacy of percutaneous balloon dilatation and temporary internal stenting in the treatment of transplant ureteral strictures. METHODS Nine patients presenting with obstructed renal transplants were treated by antegrade nephrostomy insertion, ureteroplasty, and temporary internal stenting. Following stent removal, patients were divided into two groups for analysis according to whether the obstruction occurred less than (group A) or more than (group B) 3 months following transplantation. RESULTS All procedures were technically successful. In group A (n = 6), all patients were successfully treated by one or two dilatations with stenting. In group B (n = 3), two patients were successfully treated by one dilatation with stenting. Overall, eight patients (89%) have had their primary or secondary stent removed successfully at a mean interval of 97.5 days after insertion, and remain well at a mean follow-up interval of 22 months. CONCLUSION Balloon dilatation and temporary internal stenting is a useful method for treating transplant ureteral strictures.

Abstract
PURPOSE Urologists successfully use ureteral stents to protect the ureterovesical anastomosis in nontransplant patients. MATERIALS AND METHODS We determined the value of ureteral stents in transplant patients. The frequency of urological complications (leaks, obstructions and urinary tract infections) was compared in a prospective randomized series of 194 kidney transplantations (97 with and 97 without a double pigtail ureteral stent). RESULTS In the stent group 1 patient had a urinary leak and 35 had urinary tract infections (including 2 cases of Corynebacterium cystitis). In the no stent group 6 patients had urinary leaks, 4 had obstructions and 32 had urinary tract infections. The 1-year patient and graft survival rates were similar in both groups, and renal function at 1 year was also similar (229 versus 208 mumol./l. creatinine in the stent and no stent groups, respectively). A small number of stent related complications occurred (2 stent breakages and 1 stent migration). No stones formed in any case. CONCLUSIONS Ureteral stent insertion significantly decreases the rate of vesicoureteral leakage and obstruction in renal transplantation.

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
Because of the altered anatomy, the presence of immunosuppression, the possibility of graft rejection, and the serious implications of a problem involving a solitary kidney, the transplanted kidney presents unique challenges in the diagnosis and treatment of urologic complications. Historically, the mortality rate in these patients has been as high as 68%, and as many as 15% of the allografts have been lost. Today, endourologic procedures are used for prompt diagnosis, temporization, and even definitive management of many urologic complications, and many patients and allografts are being saved. The authors review present techniques and suggest others that may be available in the future.

Abstract
Cold-knife incision of stenoses in the transplant ureter was performed in 11 patients with upper urinary tract obstruction in renal transplants. The operations were complicated by bleeding in 2 patients and the graft had to be removed in 1 of them. The stenoses could be treated successfully in 10 of the 11 patients (91%) and the mean serum creatinine concentration decreased significantly from 3.4 to 1.8 mg./dl. After a mean of 26 months only 1 obstruction recurred, so the long-term success rate was 82%. Because of the favorable long-term results and the low incidence of complications, we recommend endo-urological cold-knife incision of ureteral stenosis as the first-line treatment for upper urinary tract obstruction in renal transplants.

Abstract
Transplant ureteral stricture can be treated by either incisional surgery or percutaneous endoluminal dilation. We present 17 cases of percutaneous antegrade endoluminal dilation. The results of this procedure were satisfactory, with a 70% success rate that seems to be maintained during long-term followup. The results were better if dilation was done on a short and recent juxta-anastomotic stricture stented with a 10F Double-J* catheter for 2 months.

Abstract
Transluminal ureteral dilation was performed in 11 renal allograft recipients with transplant ureteral obstruction. Success was achieved in 5 patients (45 per cent) with a followup of 12 to 29 months (mean 19.6 months). All failures have been evident within 12 months of dilation. We conclude that ureteral dilation can provide long-term success in renal allograft recipients. However, continued close long-term monitoring of the anatomical and functional result is mandatory for patients treated in this manner.

Abstract
While conventional methods of urethroplasty for posterior urethral disruption usually are successful technically, they may be associated with complications and often require the expertise of a specialist. Therefore, the option of an endourological approach to the treatment of the obliterated posterior urethra would be highly desirable if a comparable surgical outcome could be achieved. We describe a closed controlled method of posterior urethral reconstruction following traumatic avulsion of the posterior urethra. Urethral continuity was re-established by endoscopic identification of the true prostatic outlet, its fixation with an angiography wire and a Goodwin sound, retrograde visual urethrotomy through the fibrotic segment and balloon dilation of the entire posterior channel. Postoperative anatomical and functional results were excellent, and were achieved with much less risk and cost to the patient than those of a perineal or transpubic urethroplasty.

Abstract
We report a 52-year-old male renal transplant recipient who had three "rejection episodes." The first of these responded to conventional antirejection therapy; however, the next two episodes showed incomplete responses to treatment for rejection. At subsequent presentation with deteriorating renal function, ureteral obstruction was evident and was relieved with percutaneous antegrade balloon dilatation with a return of his plasma creatinine to normal. Obstruction of the ureter was a major component in our patient's course given the lack of response to conventional antirejection therapy and the normalization of renal function with relief of the documented ureteral stenosis. This case illustrates that ureteral obstruction can mimic rejection in the renal transplant recipient. Management of ureteral stenosis in transplant patients with percutaneous antegrade balloon dilatation appears to be an effective procedure and can supplant the need for open surgical procedures.

Abstract
Percutaneous techniques were used to manage 13 renal transplant recipients with urological complications and long-term followup now is available. Three patients had urinary fistulas and 10 had ureteral obstruction. In 2 of the patients with ureteral fistulas and 5 with ureteral obstruction the percutaneous procedures provided definitive management and obviated the need for an open operation. In the 6 other patients the percutaneous procedures proved to be valuable adjuncts to subsequent planned open operative reconstruction. While there were 4 significant complications related to the percutaneous procedures, none resulted in graft loss or patient death. We conclude that percutaneous techniques provide valuable alternatives to immediate open operative intervention in renal transplant recipients with ureteral obstruction or fistula formation. Furthermore, these techniques may obviate entirely the need for subsequent operative intervention.

Abstract
Following kidney allotransplantation a great number of complications threaten the patient and his graft, e.g. acute tubular necrosis, acute and chronic rejection, urologic and vascular complications and complications due to the immunosuppressive treatment. During the last decade a number of technical developments in radionuclide, ultrasonographic and radiographic imaging and intervention has significantly improved the possibility of early recognition and handling of such complications. Knowledge of the capability and limitations of the various techniques is of vital importance for their rational use. The aim of this review article is to give a short description of the various imaging modalities, the rational monitoring of the posttransplant patient, and possible handling of complications by the aid of imaging techniques.

Abstract
The use of a recipient ureter ureterocalycostomy in the management of ureteral obstruction in a renal transplant recipient is presented. This technique can be used when primary modes of reconstruction are unavailable and nephrectomy is the only alternative.

Abstract
The use of percutaneous endourological techniques is demonstrated in recipients of renal allografts. Transplant complications that previously had required prompt surgical intervention may be approached safely by the judicious use of percutaneous manipulations. While examples of perirenal hematoma, renal abscess, urinary fistula and renal pelvic stone extraction are presented, close patient observation and a low threshold for surgical intervention are recommended to permit the continued, safe evaluation of this approach.

Abstract
Ureteral strictures are uncommon problems in urological practice. The nonvascular application of the Grüntzig balloon catheter is proposed as an alternative to surgery in some of these patients. We treated 6 ureteral strictures in 5 patients by balloon dilation with an 83 per cent success rate.

Abstract
A transurethral or percutaneous procedure was used in 11 children and 1 young adult in an attempt to correct obstruction at the site of previous pyeloplasty, ureteroenterostomy or vesicoureteral reimplantation into the bladder. When a guide wire could be passed through the obstructed segment a balloon would always pass over the wire. The balloon could then be inflated to dilate the narrowed area. Five patients in whom the obstruction was detected and treated in this manner within a few months after the initial operation exhibited relief of obstruction and these good results have persisted. The exception to this generalization is a 5-year-old girl who did not experience durable improvement in obstruction when treated 3 months after ureteral implantation. Four additional children with ureteral strictures diagnosed 1 to 4 years postoperatively also were not improved by dilation, even when a post-dilation stent (usually a double-J catheter) was used for 6 to 8 weeks. Two boys with recurrent ureteropelvic junction obstruction after pyeloplasty underwent percutaneous resection of the ureteropelvic junction. In 1 boy the hook electrode and cautery were used and stenosis recurred, apparently due to thermal injury. In the other boy a sharpened hook electrode was used to incise the ureteropelvic junction, which has stayed open for 18 months, and he is our longest followup.

Abstract
The percutaneous nephrostomy tract provides ready access with a nephroscope to the upper ureter directly allowing the urologist to remove stones and to perform operative procedures such as endopyelotomy. The tract also permits antegrade insertion of ureteral stents and ureteral catheters to which other instruments can be attached, this facilitating stone basketing, controlled ureteral meatotomy, and retrograde stent insertion.
