Background/Objectives: Kidney transplantation is the treatment of choice for children with end-stage renal disease (ESRD), but its outcome can be affected by urological complications, with incidence rates of 2.5–25%. The aim of this study was to evaluate the occurrence of urological complications and their management in a cohort of pediatric kidney transplant recipients. Materials and Methods: A retrospective analysis on 178 patients who received a renal transplant at our Pediatric Kidney Transplant Center between 2011 and 2023 was conducted. Demographic and clinical data were analyzed. Urological complications were categorized as early, intermediate, or late based on their onset time. Results: Out of 178 patients, 28 (15.7%) experienced urological complications. Most patients (61%) had a pre-existing uropathy. Early complications (7–30 days) were all obstructive, namely, ureterovesical junction obstruction and perirenal collections. Intermediate complications (1–3 months) comprised ureteral stenosis, symptomatic vesicoureteral reflux (VUR), and obstructive lymphocele. Late complications (>3 months) included symptomatic VUR and ureteral stenosis, with one case leading to ureteral rupture. Early complications were often detected due to acute graft dysfunction, while late ones were mainly identified during routine clinical, laboratory, or ultrasound follow-up. Urological complications requiring surgical or endoscopic therapy were 13.4%. Most ureteral stenoses were treated with initial endoscopic stents, followed by definitive surgery. VUR was treated with endoscopic correction with a high success rate (75%), while open surgery was reserved for cases where initial treatments failed or complications recurred. No clear correlations were found between patient characteristics and risk of urological complication. Urological complications required multiple diagnostic procedures and therapeutic interventions (+2.5 admissions in mean and approximately +EUR 24,000) compared to an uncomplicated post-transplant course. However, they did not significantly impact transplant outcomes, with a graft survival rate comparable to that of the control group. Conclusions: Regular post-transplant follow-up is crucial, especially for patients with known risk factors, to allow for timely detection and treatment of urological complications, avoiding detrimental effects on graft function and improving transplantation outcomes.

Abstract Background Use of ureteral stents has become an integral part of urological practice. However, it also brought with it many complications. Double J (DJ) stent knotting is a rare stent complication, and only a few cases have been reported in the literature. Although the exact cause is unknown and, in the literature, it is generally thought that knots occur due to traction. In this case report we present for the first time that spontaneous knots can occur due to ureteral peristalsis or ureteral anomalies. Case presentation Two patients (67 and 35 aged-Caucasian person) with ureteral stones who presented to the emergency department with colicky pain and had no previous history of urological surgery. We observed knot formation in the routine urinary system radiographs taken before stent removal in two patients whose ureters were observed to be narrow during endoscopic ureteral stone treatment. The stents were successfully removed using gentle traction under general anesthesia. Conclusions We discussed the cause and solution of spontaneous knot formation. We emphasized the importance of the direct urinary system radiograph taken before DJ stent removal.

Objective: To report on the occurrence of urological complications in women undergoing Cesarean section for placenta accreta spectrum disorders (PAS). Methods: MEDLINE, EMBASE and the Cochrane databases were searched electronically up to 1 November 2022. Studies reporting on the urological outcome of women undergoing Cesarean section for PAS were included. Two independent reviewers performed data extraction using a predefined protocol and assessed the risk of bias using the Newcastle–Ottawa scale for observational studies, with disagreements resolved by consensus.The primary outcome was the overall occurrence of urological complications. Secondary outcomes were the occurrence of any cystotomy, intentional cystotomy, unintentional cystotomy, ureteral damage, ureteral fistula and vesicovaginal fistula. All outcomes were explored in the overall population of women undergoing surgery for PAS. In addition, we performed subgroup analyses according to the type of surgery (Cesarean hysterectomy, or conservative surgery or management), severity of PAS at histopathology (placenta accreta/increta and placenta percreta), type of intervention (planned vs emergency) and number of cases per year. Random‐effects meta‐analyses of proportions were used to analyze the data. Results: There were 62 studies included in the systematic review and 56 were included in the meta‐analysis. Urological complications occurred in 15.2% (95% CI, 12.9–17.7%) of cases. Cystotomy complicated 13.5% (95% CI, 9.7–17.9%) of surgical operations. Intentional cystotomy was required in 7.7% (95% CI, 6.5–9.1%) of cases, while unintentional cystotomy occurred in 7.2% (95% CI, 6.0–8.5%) of cases. Urological complications occurred in 19.4% (95% CI, 16.3–22.7%) of cases undergoing hysterectomy and 12.2% (95% CI, 7.5–17.8%) of those undergoing conservative treatment. In the subgroup analyses, urological complications occurred in 9.4% (95% CI, 5.4–14.4%) of women with placenta accreta/increta and 38.5% (95% CI, 21.6–57.0%) of those described as having placenta percreta, and included mainly cystotomy (5.5% (95% CI, 0.6–15.1%) and 22.0% (95% CI, 5.4–45.5%), respectively). Urological complications occurred in 15.4% (95% CI, 8.1–24.6%) of cases undergoing a planned procedure and 24.6% (95% CI, 13.0–38.5%) of those undergoing an emergency intervention. In subanalysis of studies reporting on ≥ 12 cases per year, the incidence of urological complication was similar to that reported in the primary analysis. Conclusions: Women undergoing surgery for PAS are at high risk of urological complication, mainly cystotomy. The incidence of these complications was particularly high in women described as having placenta percreta at birth and in those undergoing emergency surgical intervention. The high heterogeneity between the included studies highlights the need for a standardized protocol for the diagnosis of PAS to identify prenatal imaging signs associated with the increased risk of urological morbidity at delivery. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

IntroductionUrologic complications (UCs) and urinary tract infections (UTIs) are common after kidney transplantation. Intraoperative stent placement at the vesicoureteric anastomosis reduces UC risk, but increases UTI risk.MethodsIn 2014 our stenting protocol changed from external ureteric stent (ES) to internal double J stent (DJ). We retrospectively studied the occurrence of UCs and UTIs in relation to ES or DJ in 697 kidney recipients.MethodsAn ES was used in 403 patients (57.8%), in 294 (42.2%) a DJ. ES was removed 7-12 days and DJ 3-4 weeks post-operative. Induction immunosuppression was the same in both groups. Primary outcomes at 6 months follow-up were UC (urinary leakage/ureter stenosis) and UTI; they were related to stenting procedure and clinical and transplant characteristics. The incidence of UCs was similar for ES (8.4%) and DJ (6.8%), p=0.389. ES use was a significant risk factor for UTI (OR 1.69 (1.15-2.50), p=0.008). Post-transplant hospitalization was significantly shorter in the DJ group. Despite more acute rejection episodes with ES (ES/DJ: 16.4%/6.1%, p

Many complications due to double j (DJ) stent placement have been reported. DJ stent knotting is a rare complication, with only a few cases reported in the literature. We presented a case of DJ stent knotting and reviewed the literature regarding this complication. We reported a 20-year-old man with a history of cystinuria and ureteral stone managed with retrograde ureteroscopy and holmium laser three months ago. The patient comes for DJ stent removal. Firstly, we tried to remove the DJ stent via the cystoscopic procedure, which failed. A fluoroscopic image revealed a knotted DJ stent lodged at the ureteropelvic junction and was removed via holmium laser ureteroscopic procedure without complications. In conclusion, when cystoscopic procedure with simple traction fails to remove DJ stents, multimodality urological procedures such as holmium laser should be tried, especially in patients with urolithiasis predisposing factors.

The overall complication rate of Transurethral resection of prostate (TURP) is about 11.1%. Amongst all complications, ocular complications are one of the rarest. In this paper, we present a case of vision loss due to paradoxical embolism as a rare complication following TURP. Ocular complications are very rare in urological surgeries but can happen due to paradoxical embolism following patent foramen ovale. Therefore, we recommend the early diagnosis and treatment of PFO prior to this type of surgery.

Aims: Purposes of this study were to describe lower urinary tract symptoms (LUTS) and related urodynamic patterns in patients with hereditary spastic paraplegia (HSP), and to characterize LUTS management and associated uronephrological complications. Methods: We retrospectively reviewed medical files of HSP patients, consecutively followed in our Physical and Rehabilitation Medicine Department between 1999 and 2016. Clinical, urodynamic, and radiological data were collected and analyzed. Different treatments which have been prescribed and uronephrological complications were also recorded. Patients with other neurological or urological diseases were excluded. Results: Thirty‐three patients with HSP were included. Mean duration of follow‐up was 8.1 ± 5 years, mean age 62 ± 14 years, and 70% were men. The most frequent LUTS was urgency and voiding dysfunction (both 69.7%). Incontinence and retention with a significant postvoid residue above 100 mL accounted for 66.7% and 57.6% of initial symptoms respectively. Neurogenic detrusor overactivity was diagnosed in 80.7% of patients. Two‐thirds of our cohort were treated with anticholinergics and 9.1% required intradetrusor botulinum‐toxin injections. Only 27.3% of patients performed clean intermittent self‐catheterization. Febrile urinary tract infections (21.2%), urolithiasis (15,1%), hydronephrosis (6%), and chronic renal failure (9.1%) were found. Conclusion: Given their high prevalence and the risk of uronephrological complications, LUTS should be systematically assessed in HSP patients. The systematic screening of urological dysfunction in this population would improve its management, decrease the incidence of uronephrological complications, and increase the quality of life.

This article reports the current evidence and expert opinions on diagnosis and management of neurogenic lower urinary tract dysfunction (NLUTD) in Taiwan. The main problems of NLUTD are failure to store, failure to empty, and combined failure to store and empty. The priority of management of NLUTD should follow the order of: (1) preservation of renal function; (2) freedom from urinary tract infection (UTI); (3) efficient bladder emptying; and (4) freedom from indwelling catheter, and patients' expectation of management should be respected. Management of the urinary tract in patients with spinal cord injury (SCI) or multiple sclerosis (MS) must be based on urodynamic findings, rather than inferences from the neurologic evaluation. Selecting high risk patients is important to prevent renal function impairment in patients with chronic NLUTD. Patients with NLUTD should be regularly followed up for their lower urinary tract dysfunction by urodynamic study and any urological complication should be adequately treated. Avoiding a chronic indwelling catheter can reduce the incidence of developing a low compliant bladder. Antimuscarinic agents with clean intermittent catheterization (CIC) may reduce urological complications and improve quality of life (QoL) in patients with NLUTD. Intravesical injection of botulinum toxin A provides an alternative treatment for refractory detrusor overactivity (DO) or low compliant bladder and can replace the need for bladder augmentation. When surgical intervention is necessary, we should consider the least invasive type of surgery and reversible procedure first and avoid any unnecessary surgery of the lower urinary tract. Keeping the bladder and urethra in a good condition without interference of the neuromuscular continuity provides patients with NLUTD a chance for future new technologies. It is most important to never give up on improving the QoL in patients with NLUTD.

Objectives To evaluate the risk for urological complications after kidney transplantation at a single medical center in Japan. Methods In the present study, 408 kidney recipients (255 men, 153 women) were enrolled. There were 349 living and 59 deceased donors. The average age of the recipients was 42.5 ± 13.5 years, and the average pretransplant dialysis period was 71.8 ± 88.2 months. Ureteroneocystostomy was carried out on 347 patients, and ureteroureterostomy on 61 patients. We investigated the relationship between pretransplant duration of dialysis and bladder capacity, and examined the risk factors for urological complication. We also evaluated the incidence of vesicoureteral reflux in 191 recipients who underwent ureteroneocystostomy during transplantation. Results The preoperative duration of dialysis therapy showed a significant negative correlation with bladder capacity ( R2 = 0.33, P < 0.001). The overall urological complication rate was 3.4% (14 patients), including urinary leakage (12 patients) and ureteral stricture (two patients). Univariate analysis showed that atrophic bladder, long-term dialysis therapy, deceased donor and ureteroureterostomy were associated with a higher incidence of urological complications (odds ratio 8.05, 4.43, 3.42 and 3.35; P < 0.01, P = 0.01, P = 0.04 and P = 0.04, respectively). Furthermore, multivariate analysis showed that atrophic bladder was the only significant factor associated with urological complications (odds ratio 10.37; P = 0.01). Among 191 recipients, vesicoureteral reflux was observed in 32 (16.8%). The incidence of vesicoureteral reflux was significantly higher in patients with atrophic bladder. Conclusions Bladder atrophy in renal transplant recipients after long-term dialysis therapy is associated with a higher risk of urological complications. [ABSTRACT FROM AUTHOR]

The indications for ureteral stent placement have expanded significantly with the progress of surgical procedures and techniques. Although such stents are now an integral part of contemporary urological practice, their use is not free of complications and consequences. There are very rare descriptions of knot formation in a ureteral stent and the consequences of this occurrence, with only 12 cases previously reported. Here, we report an additional case and review all the literature concerning this urological complication with emphasis on its predisposing factors and conservative and surgical management.

This article reports the current evidence and expert opinions on the diagnosis and management of neurogenic lower urinary tract dysfunction (NLUTD) in Taiwan. The main problems of NLUTD are failure to store, failure to empty, and a combination of these two. Priorities in the management of NLUTD, in order of importance, should be the following: (1) preservation of renal function; (2) freedom from urinary tract infection; (3) efficient bladder emptying; (4) freedom from indwelling catheters; (5) patient agreement with the management modality; and (6) avoidance of medication after proper management. Management of the urinary tract in patients with spinal cord injuries or multiple sclerosis must be based on urodynamic findings rather than on inferences from the neurological evaluation. Identification of high-risk patients is important to prevent renal functional impairment in those with chronic NLUTD. The lower urinary tract function of patients with NLUTD should be regularly followed up by urodynamic study, and any urological complication should be treated adequately. Avoiding a chronic indwelling catheter can reduce the incidence of developing a low compliant bladder. Intravesical instillation of vanilloids and injecting botulinum toxin-A are alternative treatments for refractory detrusor overactivity or a low compliant bladder, and can replace the need for bladder augmentation. When surgical intervention is necessary, less invasive types of surgery and reversible procedures should be considered first, and any unnecessary surgery in the lower urinary tract should be avoided. Keeping the bladder and urethra in good condition without the interference of neuromuscular continuity provides patients with NLUTD the opportunity to use new technologies in the future. Improving the quality of life in patients with neurogenic voiding dysfunction is the most important aspect of treatment. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: Neurogenic voiding dysfunction (NVD) results in lower urinary tract symptoms and upper urinary tract complications. Management of urinary tract dysfunction in patients with spinal cord injury (SCI) must be based on patient needs and urological complications. This study surveyed the bladder management and urological complications in patients with SCI in Taiwan. Materials and methods: A total of 894 patients with SCI were surveyed throughout Taiwan over a period of 5 years (2007–2011). All patients received neurological and urological examinations, renal sonography, bladder sonography, and urinalysis. They were further requested to report urinary tract infections (UTI), voiding conditions, and bladder management in the past 3 years. The bladder management and urological complications were analyzed based on different SCI levels and duration of disease. Results: Among all patients, 39.7% voided spontaneously or by reflex, 23.8% used percussion to void, 20.9% voided by abdominal pressure, 18.1% used clean intermittent catheterization (CIC), and 22.9% had indwelling catheters or cystostomy. Detrusor sphincter dyssynergia (DSD) was noted in 39.7% of patients and autonomic dysreflexia (AD) in 19.9%. UTI was noted in 483 (54%) patients, hydronephrosis in 110 (12.3%) patients, and severe urinary incontinence in 257 (28.7%) patients. UTI occurred significantly more often in patients without, than with normal voiding. CIC was more frequently used in patients with duration of SCI < 1 year, but the rate of CIC significantly decreased as the duration of SCI increased. Conclusion: The rates of urological complications in patients with chronic SCI remained high in this survey in Taiwan. Patients with a duration of SCI > 5 years chose indwelling catheters or a cystostomy more often than CIC. [Copyright &y& Elsevier]

ABSTRACT: Background: There is a growing number of overweight and obese patients receiving kidney transplants, despite elevated body mass index (BMI) being associated with postoperative complications. Understanding associations between BMI and complications would allow more objectivity when recommending patients for transplantation or otherwise. Methods: We analysed a retrospective cohort of 508 adult patients who received primary kidney grafts at a single centre in South Australia, 2002-2009, using hospital records and Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) data. Complications within 1 year of transplantation were classified into: surgical, wound, urological, delayed graft function, early nephrectomy and admission to intensive care unit (ICU). Results: Overall, 62% of transplant recipients had a BMI above 25 kg/m2 at transplant. Higher BMI was associated with an increased risk of wound complications ( P < 0.001), early nephrectomy ( P = 0.002) and delayed graft function ( P = 0.03), but not associated with surgical or urological complications, or ICU admission. These associations were stronger for Indigenous Australians than other patients, especially for surgical complications. There was no BMI value above which risks of complications increase substantially. Conclusion: Delayed graft function is an important determinant of patient outcomes. Wound complications can be serious, and are more common in patients with higher BMI. This may justify the use of elevated BMI as a contraindication for transplantation, although no obvious cut-off value exists. Investigations into other measures of body fat composition and distribution are warranted. [ABSTRACT FROM AUTHOR]

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.

Urological complications after kidney transplantation may result in significant morbidity and mortality. However, the incidence of such complications after deceased cardiac death (DCD) donor kidney transplantation and their effect on survival is unknown. Purpose of this study was to estimate the incidence of urological complications after DCD kidney transplantation, and to estimate their impact on survival. Patient records of all 76 DCD kidney transplantations in the period 1997–2004 were reviewed for (urological) complications during the initial hospitalization until 30 days after discharge, and graft survival until the last hospital visit. Urological complications occurred in 32 patients (42.1%), with leakage and/or obstruction occurring in seven patients (9.2%). The latter seems to be comparable with the incidence reported in the literature for deceased heart-beating (DHB) transplantations (range 2.5–10%). Overall graft survival was 92% at 1 year and 88% at 3 years, comparable to the rates reported in the literature for kidneys from DHB donors, and was not affected by urological complications (χ2 = 0.27, P = 0.61). Only a first warm-ischaemia time of 30 min or more reduced graft survival (χ2 = 4.38, P < 0.05). We conclude that urological complications occur frequently after DCD kidney transplantation, but do not influence graft survival. The only risk factor for reduced graft survival in DCD transplant recipients was the first warm-ischaemia time. [ABSTRACT FROM AUTHOR]

Abstract: The main problems in neurogenic voiding dysfunction (NVD) are failure to store, failure to empty, and combined failure to store and empty. The management priorities in NVD should be as follows, in order: (1) preservation of renal function, (2) freedom from urinary tract infection, (3) efficient bladder emptying, (4) freedom from an indwelling catheter, (5) patient satisfaction with voiding management and (6) avoiding medication after proper management. Management of the urinary tract in patients with spinal cord injury must be based on urodynamic findings rather than inferences from a neurologic evaluation. Selecting high-risk patients is important to prevent renal function impairment in patients with chronic NVD. Patients with NVD should be regularly followed-up for lower urinary tract dysfunction using urodynamic study and any urological complication should be adequately treated. Avoiding a chronic indwelling catheter can reduce the incidence of developing a low compliant bladder. Intravesical instillation of vanilloids or injection of BOTOX provides an alternative treatment for refractory detrusor overactivity or low compliant bladder and can replace the need for bladder augmentation. When surgical intervention is necessary, a less invasive type of surgery and a reversible procedure should be considered first and unnecessary surgery in the lower urinary tract should be avoided. Keeping the bladder and urethra in good condition without interfering with neuromuscular continuity will give patients with NVD a chance to benefit from new technologies in the future. It is most important that the physician continues to try to improve the quality of life of patients with NVD. [Tzu Chi Med J 2008;20(1):35–39] [Copyright &y& Elsevier]

In order to assess the incidence and type of urologic complications associated with Wertheim's radical hysterectomy we studied all 154 patients undergoing radical hysterectomy at our department between 1980 and 1986. More than 2/3 of patients had stage I carcinoma of the cervix, the mean age was 46.9 years (range 27-73 years). Various intraoperative reconstructive procedures were required in 5%. A comparison with the experience of Wertheim (before 1919) and that of a subsequent time period (1952-1967) showed that while the incidence of intraoperative injury to the lower urinary tract remained stable, the incidence of postoperative fistula formation decreased significantly (from 6.4% to 0.6%), possibly due to changes in the operative technique. We conclude that Wertheim's radical hysterectomy now involves only a very low risk of injury to the bladder or to the ureter. [ABSTRACT FROM AUTHOR]

Caliceal fistula is a rare urological complication that can occur usually shortly after kidney transplantation (KTx). The occlusion of the renal accessory artery with subsequent necrosis of the kidney pole is the most common cause of the fistula development. We report a case of a 57-year-old man with reconstruction of two accessory renal arteries by anastomosis to the side of the main artery during graft placement complicated by late caliceal fistula, managed surgically. Directly after KTx good kidney graft function (serum creatinine concentration 151 µmol/L) was observed. The patient noticed protuberance and pain in the kidney graft area 5 months later. Diagnostic imaging revealed moderate urostasis and liquid collection in the region of the lower graft pole. Administration of a contrast medium through the inserted drain visualized a fistula of a lower renal calyx and ureteric stenosis. Percutaneous drainage was applied with subsequent stop of diuresis through the urethral catheter. During the surgery, the resection of a lower kidney graft pole necrosis was performed, with the closure of caliceal fistula. Simultaneously double pigtail ureteric stent was inserted. After the next two months the pigtail catheter was removed, and neither urostasis in the kidney graft nor liquid collection in the perigraft area were observed. The exceptionality of the case is the late caliceal fistula occurrence. We may only speculate, why it happened 5 months after KTx. The thrombosis of stenosed accessory artery is the most probable cause. [ABSTRACT FROM AUTHOR]

Background: Menkes disease (MD) is a rare X-linked hereditary multisystemic disorder that is caused by dysfunction of copper metabolism. Patients with MD typically present with progressive neurodegeneration, some connective tissue abnormalities, and characteristic "kinky" hair. In addition, various types of urological complications are frequent in MD because of underlying connective tissue abnormalities. In this study, we studied the clinical features and outcomes of MD, focusing on urological complications., Methods: A total of 14 unrelated Korean pediatric patients (13 boys and 1 girl) with MD were recruited, and their phenotypes and genotypes were analyzed by retrospective review of their medical records., Results: All the patients had early-onset neurological deficit, including developmental delay, seizures, and hypotonia. The girl patient showed normal serum copper and ceruloplasmin levels as well as milder symptoms. Mutational analysis of the ATP7A gene revealed 11 different mutations in 12 patients. Bladder diverticula was the most frequent urological complication: 8 (57.1%) in the 14 patients or 8 (72.7%) in the 11 patients who underwent urological evaluation. Urological imaging studies were performed essentially for the evaluation of accompanying urinary tract infections. Four patients had stage II chronic kidney disease at the last follow-up., Conclusion: Urologic problems occurred frequently in MD, with bladder diverticula being the most common. Therefore, urological imaging studies and appropriate management of urological complications, which may prevent or reduce the development of urinary tract infections and renal parenchymal damage, are required in all patients with MD., Competing Interests: Disclosure: The authors have no potential conflicts of interest to disclose.

Background: We aimed to clarify renal functional changes long term and serious urological complications in women with cervical cancer who undergo radical hysterectomy followed by pelvic radiotherapy and/or platinum-based chemotherapy to treat the initial disease., Methods: Data on 380 women who underwent radical hysterectomy at the National Kyushu Cancer Center from January 1997 to December 2013 were reviewed. Main outcome measures were the estimated glomerular filtration rate (eGFR) and monitored abnormal urological findings., Results: Postoperative eGFR was significantly lower than preoperative eGFR in 179 women with surgery alone and in 201 women with additional pelvic radiotherapy and/or chemotherapy (both P < 0.01). Two types of univariate analyses for eGFR reduction in women after treatment showed that older age, advanced stage, pelvic radiotherapy, and platinum-based chemotherapy were significant variables on both analyses. Two types of multivariate analyses showed that platinum-based chemotherapy or pelvic radiotherapy were associated with impaired renal function (odds ratio 1.96, 95% confidence interval 1.08-3.54 and odds ratio 2.85, 95% confidence interval 1.12-7.24, for the respective analyses). There was a higher rate of bladder wall thickening in women with pelvic radiotherapy had than those without it (17.4% vs. 2.7%, P < 0.01). One serious urological complication (intraperitoneal rupture of the bladder) occurred among women who underwent pelvic radiotherapy (0.6% vs. 0%)., Conclusions: Surgeons should be aware that eGFR is reduced after platinum-based chemotherapy and/or postoperative pelvic radiotherapy. Serious and life-threatening urological complications are rare, but surgeons should be aware of the possibility during the long follow-up., (© The Author 2017. Published by Oxford University Press.
