Abstract
PURPOSE An abnormal lower urinary tract poses significant challenges for transplant surgeons. Besides the ureteral anastomosis to an ileal conduit, there are diverse complex reconstructive solutions. Due to its rarity, standardization and teaching of complex urinary diversion is extremely difficult. METHODS The indications and outcomes of complex urinary diversions after kidney transplantation (KT) were retrospectively investigated at eight urologic transplant centers including a current follow-up. RESULTS Of 37 patients with 21 (56%) males, vesicoureteral reflux (24%), spina bifida (22%), and glomerulonephritis (12%) were the most common causes of terminal renal failure. In 30 (81%) patients, urinary diversion was performed before KT, at a median of 107.5 (range, 10; 545) months before. Transplantations were held at a median patient age of 43 (10; 68) years, including six (16%) living donations. Urinary diversion was modified during 12 (32%) transplantations. After KT, the ileal conduit was the most common incontinent urinary diversion in 25 (67%) patients; a Mainz pouch I and bladder augmentation were the most frequent continent diversions (each n = 3). At a median follow-up of 120 months (range 0; 444), 12 (32%) patients had a graft failure with a 5-year graft survival of 79% (95%CI 61; 90). The median overall survival was 227 months (168; 286) and the 5-year overall survival 89% (69.3; 96.4). CONCLUSION The mid-term kidney transplant function with complex urinary diversion appears to be comparable to transplants with regular urinary diversions. Hence, complex urinary diversion should always be considered as a surgical option, even during transplantation, if necessary.

Abstract
BACKGROUND Augmentation cystoplasty (AC) has been recently proposed to improve a bladder condition before or after a renal transplantation for an optimal allograft function. Until now, AC in adults with end-stage renal disease (ESRD) is uncommon and rarely practiced. This study aimed to investigate the safety of AC in patients with bladder abnormalities who required renal transplantation.
METHODS Studies of patients with ESRD and abnormal bladder who underwent AC were searched in ProQuest, PubMed, EBSCO, and Cochrane Library online databases. Only studies published in English from January 1985 to May 2020 were included. The keywords used were renal transplantation, bladder dysfunction, cystoplasty, and their synonyms. Data were extracted by two independent authors who selected, screened, and assessed the articles’ eligibility and quality. The outcomes were graft survival rate and complications of AC.
RESULTS A total of 19 articles were included. AC improved an intravesical pressure, a bladder capacity, and a compliance in patients with ESRD and bladder abnormalities, allowing patients to undergo the renal transplantation. Even though AC in patients with renal transplantation resulted in a significantly higher urinary tract infection rate than patients who underwent renal transplantation only, performing AC after renal transplantation was considered safe.
CONCLUSIONS AC was considered safe for patients with bladder abnormalities who underwent renal transplantation.

Abstract
Background The effects of renal transplantation in patients with augmentation cystoplasty are still controversial. We retrospectively analyzed nine patients who underwent renal transplantation after augmentation cystoplasty. Methods A total of nine patients who underwent augmentation cystoplasty prior to renal transplantation between January 1990 and May 2020 were reviewed. Basic information on augmentation cystoplasty, transplant procedures, and long-term outcomes of renal transplantation were analyzed. Results The bowel segments utilized for augmentation cystoplasty were the stomach in two patients (one patient needed revision using the ileum), the ileum in four patients, the ileocolic pouch in one patient, the sigmoid in one patient, and the ureter in one patient. All the cystoplasties were performed prior to renal transplantation. The mean follow-up period after transplantation was 161 months (range, 2–341 months). Two patients had an episode of acute rejection each; however, their graft functions were well-maintained. Five patients had recurrent urinary tract infections, and three of these patients progressed to allograft failure. One patient died from bladder cancer with a functioning graft. Five of nine patients showed well-maintained graft function. Conclusions Renal transplantation after bladder augmentation surgery is a major operation requiring a high level of surgical skill. Based on our long-term experiences, we recommend diligent postoperative monitoring for urinary tract infections, optimal catheter use, and use of appropriate antibiotic prophylaxis to avoid severe complications.

Abstract
Renal transplantation involving anatomically or functionally altered recipient urinary reservoirs is a challenging procedure. Initial reports discouraged kidney transplantation in patients with urinary diversion due to inferior outcomes. However, more recent studies have shown that although there are more infectious complications, patients with urinary diversions have comparable long-term graft survival with those with native anatomy. Careful preoperative assessment of these candidates is mandatory. Unique technical and surgical concepts must be considered before embarking on transplanting this specific cohort of kidney transplantation candidates.

Abstract
BACKGROUND/OBJECTIVE Renal failure remains one of the most significant causes of morbidity in patients with anorectal malformations (ARM). In the modern era, an increasing number of children born with ARM and genito-urinary (GU) anomalies reach adulthood and require continued multidisciplinary care for the rest of their life. The aim of this study is to present our institutional experience in the management of pediatric chronic renal failure related to severe GU anomalies and anorectal malformations. METHODS AND RESULTS Three hundred twenty-one patients with ARM have been followed at our institution since 1987. Six patients developed end-stage renal disease (ESRD) and received a kidney transplant at different ages. One patient is currently followed for mild, progressive chronic renal failure. These seven cases are reported along with a broad discussion concerning etiology of renal failure, neonatal surgical management, pediatric dialysis, urologic issues, and kidney transplantation. CONCLUSION Complex GU anomalies associated with ARM require a long-term approach by specialized pediatric and adult clinicians to optimize the care of this selected population of patients.

Abstract
PURPOSE To study the short- and long-term outcomes of kidney transplantation in patients with a bladder augmentation or urinary diversion compared to patients with a kidney transplantation in a normal functional bladder. PATIENTS AND METHODS Between January 2000 and March 2011, 13 patients received 16 grafts into a reconstructed urinary tract. We performed a retrospective case-control study and matched each patient to 4 controls for donor and recipient gender and year of transplantation. RESULTS Short- and long-term complications of kidney transplantation occurred in 12 patients, varying from urinary tract infections to medical hospitalization with or without surgical or radiological intervention. In 5 patients, a percutaneous nephrostomy (PCN) was placed followed by surgical re-intervention. In three patients, the grafts failed as a result of chronic rejection and were re-transplanted. There was no graft loss as a result of surgical complications or the reconstructed urinary tract. One-year patient and graft survival was 100 %. After five years, all patients were alive and seven of nine grafts (77.8 %) were functioning. Mean follow-up time was 4.3 years. Among the controls, 55 grafts were transplanted in 52 patients. Ten patients received a PCN. Five patients needed surgical re-intervention. In three patients, transplantectomy was performed for ongoing rejection. Three patients were re-transplanted. One patient had a failing graft 7.5 years post-transplantation and became dialysis dependent. CONCLUSION Kidney transplantation in patients with a reconstructed urinary tract has an increased complication rate. Nevertheless, the long-term results are comparable to patients with a normal urinary bladder.

Abstract
What's known on the subject? And what does the study add? There is a wealth of evidence on the development, indications, outcomes and complications of augmentation cystoplasty (AC). Over the last decade, new evidence has been emerging to influence our clinical practice and application of this technique. AC is indicated as part of the treatment pathway for both neurogenic and idiopathic detrusor overactivity, usually where other interventions have failed or are inappropriate. The most commonly used technique remains augmentation with a detubularised patch of ileum (ileocystoplasty). Controversy persists over the role of routine surveillance following ileocystoplasty for the detection of subsequent bladder carcinoma; however the indication for surveillance after gastrocystoplasty is clearer due to a rising incidence of malignancy in this group. Despite a reduction in the overall numbers of AC operations being performed, it clearly still has a role to play, which we re-examine with contemporary studies from the last decade.

Abstract
Historically, urologists were the primary surgeons in renal transplantation. Specialization and increased complexity of the field of transplantation, coupled with a de-emphasis of vascular surgical training in urology, has created a situation where many renal transplants are carried out by surgeons with a general surgery background. Because of its genitourinary nature, however, urological input in renal transplantation is still vital. For living donors, a urologist should be involved to help evaluate and prepare certain patients for eventual donation. This could involve both medical and surgical intervention. Additionally, urologists who carry out living donor nephrectomy maintain a sense of ownership in the renal transplant process and provide a unique opportunity to the trainees of that particular program. For renal transplant recipients, preoperative evaluation of voiding dysfunction and other genitourinary anomalies might be necessary before the transplant. Also, occasional surgical intervention to prepare a patient for renal transplant might be necessary, such as in a patient with a small renal mass that is detected by a screening pretransplant ultrasound. Intraoperatively, for patients with complex urological reconstructions that might be related to the etiology of the renal failure (urinary diversion, bladder augmentation), a urologist who is familiar with the anatomy should be available. Postoperatively, urological evaluation and intervention might be necessary for patients who had a pre-existing urological condition or who might have developed something de novo after the transplant. Although renal transplant programs could consult an on-call urologist for particular issues on an as-needed basis, having a urologist, who has repeated exposure to the particular issues and procedures that are involved with renal transplantation, and who is part of a dedicated multidisciplinary renal transplant team, provides optimal quality of care to these complex patients.

Abstract
OBJECTIVE We studied the long-term renal graft functions, survivals, and complications among patients with augmented bladders. PATIENTS AND METHODS Between 1976 and 2008, we performed 6/2600 renal transplantations in patients with augmented bladders. The mean patient age was 52 years. The cause of end-stage renal disease was chronic interstitial kidney disease in all patients, being secondary to lower urinary tract dysfunction. The etiology of bladder dysfunction was tuberculosis in 4 cases, bladder exstrophy in 1, and myelomeningocele in 1. Enterocystoplasty had been performed at a mean of 19 years prior to transplantation. The ureter was implanted into the native ureter in 5 cases and the bowel segment in 1 case. RESULTS With a mean follow-up of 56 months (range, 20-100 months), the overall graft survival was 50%. Three grafts were lost due to venous thrombosis (n = 1), and chronic allograft nephropathy (n = 2) at 37 and 100 months posttransplantation. No patient died during follow-up. Mean serum creatinine was 1.44 mg/dL with Modification of Diet in Renal Disease (MDRD) clearance of 76 mL/min/1.73 m(2). One fistula that caused obstructive uropathy and 2 cases of migration of a double J catheter were among the surgical complications. These patients showed a mean of 7 episodes of uncomplicated urinary infections. Only 1 patient was rehospitalized due to a complicated urinary tract infection. CONCLUSIONS Patients with enterocystoplasty and renal transplantation show a greater risk of urinary tract infections, albeit mostly uncomplicated. Despite this, the long-term results are acceptable.

Abstract
Dealing with children with bladder dysfunction and kidney transplant is certainly not a new issue. Nevertheless, it is still a matter of discussion and dilemma, based on few, not standardized, institutional center experiences. The authors perform a review of the techniques employed to restore the bladder condition in terms of storage and drainage of urine to receive a kidney transplant in a safer condition. Aspects of the etiology and the way of evaluation of such a group of patients are discussed. The strategies and individualized therapeutic options are presented and compared with the author's experience based upon 25 children with urinary anomalies who received 28 kidney transplants. Nevertheless, the number of complications, mainly UTI, graft and patient survival rates are equivalent to the group of children with non-urological causes of ESRD. Patients with severe lower urinary tract abnormalities and ESRD may receive a kidney transplant with comparable success.

Abstract
There is some controversy about the safety of kidney transplant in patients with augmented or diverted urinary system: they are considered higher risk recipients in view of increased technical problems and infective complications leading to pyelonephritis and graft loss. The ureter of a transplanted kidney should be anastomosed into a reservoir with an adequate capacity, with low bladder pressure, with good compliance, and efficient voluntary empting. Ileal and sigmoid bladder augmentation, usually associated with clean intermittent catheterization, has become a well-accepted part of the urological practice and has been used for implantation of the transplant ureter. During the last years, the interest in new biomaterials for reconstructive surgery has increased. Experimental studies showed how these requests can be satisfied by porcine small intestinal submucosa SIS (Stratasis”): this can be degraded by the host and substituted by “new tissue”. In four recent cases we have used SIS to obtain an augmented, normal-pressure and good compliance bladder reservoir, with three (epithelial, muscular and adventitial) layers normally represented.

Abstract
OBJECTIVE To compare the outcome and complications of augmentation cystoplasty before or after renal transplantation in children with neurogenic bladders, with those after kidney transplantation in children with normal bladders. PATIENTS AND METHODS Augmentation cystoplasty preceded transplantation in 21 children (group 1) and after transplantation in 23 (group 2) operated from 1985 to 2006; these two groups were compared with a control group of 45 children with a normal bladder (group 3) who also received a transplant, for kidney function, episodes of urinary tract infection (UTI), surgical and medical complications. RESULTS The mean age of the three groups was 12.9, 13.2 and 13.6 years, respectively (P = 0.2). Graft survival at 1, 3, 5 and 7 years was 90%, 76%, 65% and 43% in group 1, 94%, 61%, 50% and 40% in group 2, and 94%, 87%, 81% and 75% in group 3, respectively, which was not significantly different between groups 1 and 2, but was higher in group 3 (P = 0.03). Febrile UTI was reported in five (24%), seven (30%) and one (2%) patients in groups 1-3, respectively. UTI was significantly less frequent in group 3 (P = 0.01) but was not different between groups 1 and 2. Acute rejection was reported in nine (43%), nine (39%) and 15 (33%) patients in groups 1-3, respectively (P = 0.2). CONCLUSION The timing of cystoplasty in relation to transplantation has no apparent significant effect on the outcome of transplantation.

Abstract
OBJECTIVE To identify whether the order of performing transplant and bladder reconstruction operations in children who need both operations affects outcome of either operation. PATIENTS AND METHODS A retrospective case note review was performed of children identified from our database, who had undergone both renal transplantation and bladder augmentation between 1990 and 2005. RESULTS In all, 18 renal transplants (eight live-related) were performed in 16 children with 10 transplants done after bladder augmentation and eight transplants done before augmentation. The median age at transplantation was 7.5 years and at augmentation was 7.0 years. The median interval between the operations was 33.5 months and the median follow-up was 58.4 months after transplantation. Outcomes were compared between the two groups of patients: those who received their transplantation before bladder augmentation, and those who were transplanted after bladder augmentation. There was no difference between these groups in: the pre- transplant estimated glomerular filtration rate, inpatient stay after transplantation or after augmentation, and incidence of urinary tract infection in the 3 months after renal transplantation or after bladder augmentation. There was no statistical difference in renal allograft loss with one graft failure in the group who were augmented first, and four graft failures in the group who were transplanted first. However, it is of note that the single graft failure in the patient augmented first was due to renal artery thrombosis on the first day related to a double arterial anastomosis, whilst in the other group, three of the graft failures were in transplants that had initially been drained by ureterostomy. Three patients in the group transplanted first developed significant ureteric pathology, of which one developed graft failure. CONCLUSION Bladder reconstruction can be performed safely before transplantation; it does not increase complications and might better protect the renal graft and specifically the transplant ureter.

Abstract
OBJECTIVE To review the literature, analyse the evolution of kidney transplants (KT) in patients with bladder augmentation (BA) and investigate the relation between BA and KT. MATERIALS AND METHODS Six patients with a history of severe lower urinary tract dysfunction and BA, received a KT at our Unit between 1993 and 2003. Three had moderate renal failure at the moment of the BA. The remaining three had end stage renal failure. RESULTS With a follow-up of 7 years (mean) we have a patient survival of 100% and a graft survival of 83%. No complications occurred between the BA and the KT. The few KT complications were not related to BA. CONCLUSION When a bladder dysfunction is present, it should be treated before KT. In noncompliant bladders, BA is the best treatment. This can be done to try to avoid end stage renal failure or only to prepare the lower urinary tract for reception of the transplant. The presence of a BA did not worsen the evolution of the KT.

Abstract
Renal transplantation is the best available therapy for patients with end-stage renal failure. Urologists are often consulted regarding pretransplant evaluation and treatment of potential renal transplant recipients. Frequently the urologist is the primary surgeon in the transplant unit. This review highlights the importance of performing a comprehensive urological assessment before renal transplantation. A retrospective review of the urological and transplant literature using Medline was performed from 1976 to 2002, searching for renal transplantation and its association with urological cancers and urinary tract malformations. The pretransplant urological assessment aims to diagnose, treat, and optimize any preexisting urological disease. On occasion, certain urological diseases may not be obvious or may not have contributed to the progression to end-stage renal failure such as occult urinary tract neoplasms, urinary calculus disease, or benign prostatic hyperplasia. A thorough evaluation of the urinary tract prior to renal transplantation is mandatory to avoid unforeseen problems occurring posttransplant. If this assessment is consistently adhered to, only in very rare circumstances does a potential recipient have to be denied the opportunity of receiving an allograft based on a preexisting urological disease.

Abstract
There is some controversy about the safety of renal transplantation in patients with an augmentation cystoplasty because of the possibility of urinary tract infection in immunosuppressed patients leading to pyelonephritis and graft loss. Nevertheless, it is now well known that in patients with a small volume and poorly compliant bladder, reconstructive bladder surgery (augmentation cystoplasty or continent reservoir) creates a low-pressure and compliant reservoir, which protects the upper urinary tract and restores a functional lower urinary tract. Graft survival is not adversely affected when a kidney transplant is drained into a reconstructed bladder. When bowel segments are used for augmentation, a voiding modality with clean intermittent self-catheterization does not increase the risk of urinary tract infections, even in immunosuppressed patients.

Abstract
Urothelial augmentation in the form of augmentation enterocystoplasty continues to be the mainstay of surgical treatment for neuropathic bladder dysfunction and detrusor instability. The outcome of the procedure is satisfactory, but a number of complications are becoming more clearly defined. Computed tomography cystography is now the investigation of choice for diagnosing bladder rupture. The indications for computed tomography cystography are discussed. The current management of enterovesical fistula is reviewed.

Abstract
Up to now one of the major problems for successful organ transplantation has been the reaction of the immune system of the recipient against the donor organ. This could lead to acute and chronic rejection, and in cases of unsuccessful treatment to the loss of the transplant. In organ graft recipients, immunosuppressive agents are used to prevent or treat rejection episodes and to maintain graft function. Although there is an increasing number of immunosuppressive substances, the immunosuppressive therapy currently in use is relatively unspecific and targets many immunological functions. The net state of immunosuppression is a complex function determined by the interaction of a number of factors, the most important of these are the dose, duration and temporal sequence in which immunosuppressive drugs are employed. Any kind of immunosuppressive protocol is thus associated with an increased infection rate. This has an important socioecological impact, because frequent hospitalizations resulting from infectious complications are necessary, having an overall mortality rate of 3.5% within 2 weeks of admission. The most common cause of septicaemia is urinary tract infection. Frequent urinary tract infections are associated with the early onset of chronic rejection, suggesting a pathogenetic relationship between these two features. The occurrence of chronic rejection has led to reduced transplant survival. The prevention of urinary tract infections, or the early diagnosis and accurate treatment of urinary tract infections is important in renal transplant recipients.
