Abstract
OBJECTIVE This review investigates the prevalence of male non-neurogenic lower urinary tract symptoms (LUTS) after renal transplant, as kidney transplantation is a transformative intervention for patients with end-stage renal disease significantly enhancing quality of life that might be diminished by LUTS. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. A systematic search in the PubMed and Scopus databases was performed using specific terms. Inclusion criteria considered male kidney transplant recipients, analysing outcomes in English-language studies. Discrepancies were resolved by consultation. RESULTS Among 18 studies involving 29 086 recipients, the prevalence of non-neurogenic LUTS ranged from 5.8% to 33.0%. Studies predominantly used the International Prostate Symptom Score for evaluation. Surgical interventions, mostly for benign prostatic obstruction, ranged from 2.5% to 20.0%. Voiding and post-micturition symptoms were under-represented. CONCLUSION This review found varied non-neurogenic LUTS prevalence and characteristics in male kidney transplant recipients, emphasising the need for standardised assessments, prospective studies, and improved understanding of LUTS mechanisms. Enhanced knowledge can guide interventions, additionally benefiting recipient quality of life.

Abstract
Background Recurrent urinary tract infections (rUTIs) are common after renal transplantation (RTx), and the impact on graft and patient survival remains controversial. Objective In this study, we investigate the incidence and risk factors for rUTIs in a cohort of RTx recipients and evaluate the effect on graft and patient survival. Design setting and participants A retrospective cohort of adult patients who underwent RTx at Rigshospitalet, Denmark, between 2014 and 2021 was evaluated in this study. Outcome measurements and statistical analysis Risk factors for rUTIs were explored with a multivariable cause-specific Cox proportional hazard analysis. The Kaplan-Meier estimate was used to assess overall survival. Results and limitations A total of 571 RTx recipients were included. The median age was 52 yr (interquartile range: 42-62 yr). Of the cases, 62% were deceased donor RTx. A total of 103 recipients experienced rUTIs. We found increasing age (hazard ratio [HR]: 1.02 per year increase, 95% confidence interval [95% CI]: 1.00-1.04, p = 0.02), female gender (HR: 2.1, 95% CI: 1.4-3.3, p < 0.001), history of lower urinary tract symptoms (HR: 2.3, 95% CI: 1.4-3.5, p = 0.001), and a UTI within 30 d of surgery (HR: 3.5, 95% CI: 2.1-5.9, p < 0.001) were associated with rUTIs. No influence of rUTIs on overall or graft survival was observed. Conclusions One in six patients experience rUTIs after RTx. Pre- and postoperative variables affect the risk of rUTIs, but none are easily modifiable. In this cohort, rUTIs did not affect the graft function or survival. The etiology of rUTIs remains poorly understood, and there is a continuous need to study how rUTIs can be reduced and treated optimally. Patient summary In this study, we looked at the risk factors for recurrent urinary tract infections in patients after kidney transplantation. We conclude that 21.5% of patients experience recurrent urinary tract infections 5 years after kidney transplantation. Multiple risk factors were found and should be taken into consideration by clinicians.

Acute Urinary Retention After Kidney Transplant: Effect on Graft Function, Predictive Factors, and Treatment. Transplant Proc 2021; 53:1933-1938. [PMID: 34275596 DOI: 10.1016/j.transproceed.2021.06.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 04/03/2021] [Accepted: 06/01/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is common in older adults. Although BPH may be asymptomatic in patients with chronic kidney disease (CKD) with low diuresis, the condition may become troublesome when diuresis resumes after transplantation. This study evaluated the effect that developing acute urinary retention (AUR) in first 4 months after kidney transplantation (KT) can have on graft function at 6 months. The study identified predictive factors and analyzed treatment of AUR in these patients. METHODS This study retrospectively included 303 men who received KT. Independent samples Student t test was used to compare glomerular filtration rates (GFRs) at 6 months. Logistic regression was applied to identify predictors of AUR. RESULTS The study found that 14 patients developed AUR within the first 4 months after KT. This group had lower GFR at 6 months post-KT. Nine patients required transurethral resection of the prostate, and 2 of these patients developed acute graft pyelonephritis following resection. Residual diuresis and recipient age were predictive factors. Recipient age >55 years was a risk factor. Medical therapy of BPH before transplantation was a protective factor. CONCLUSIONS Developing AUR in the first 4 months after KT was associated with lower graft GFR at 6 months, and transurethral resection of the prostate was required in 64% of these patients, with good results. Medical therapy for BPH before the transplant was associated with a lower risk of AUR. Older patients and patients with pretransplant low urine output had a higher risk of AUR. These patients should be closely monitored in the posttransplant period for the presence of obstructive uropathy.

Abstract
INTRODUCTION Renal transplantation offers a better quality of life and survival rate for patients with end-stage renal disease. However, voiding dysfunction may have results such as decreased bladder capacity that have been observed in patients with prolonged oliguria or anuria, impacting a patient's quality of life. This study aimed to investigate preoperative factors associated with the occurrence of voiding dysfunction after renal transplantation. METHODS Seventy-one patients' data who had undergone successful renal transplantation at Cipto Mangunkusumo General Hospital in Jakarta were collected. Preoperative characteristics including age, sex, history of hypertension, diabetes mellitus, preoperative anuria, and duration of renal substitution therapy were obtained. Multivariate analysis were performed examining the correlation of preoperative characteristics with postoperative voiding dysfunction measured by International Prostate Symptom Score storage (IPSS-s) sub-score > 5, overactive bladder symptom score (OABSS) > 5, maximum flow rate (Qmax) > 15 mL/cc, and postvoid residual volume (PVR) > 50 mL. RESULTS A significant correlation of IPSS-s score suggesting storage problem with duration of preoperative dialysis was observed (odds ratio [OR] 1.052; 95% confidence interval [CI] 1.006-1.1001, P = .027). Older age and preoperative anuria were positively correlated with OABSS score > 5 (OR 1.104 and 33.567, P value .004 and .002, respectively). Negative correlation was observed between male sex and Qmax > 15mL/s (OR 1.73; 95% CI 0.033-1.907, P = .038). Male sex was negatively correlated with PVR > 50 mL (OR 0.231; P = .043) but positively correlated with the presence history of diabetes mellitus (OR 8.146; 95% CI 1.548-42.864, P = .013). CONCLUSION This study demonstrated that assessment of patient age, sex, and past medical history could help determine patients' risk for developing voiding dysfunction after renal transplantation.

Abstract
OBJECTIVES Benign prostate hyperplasia is frequently diagnosed in elderly chronic renal failure patients. Although it is asymptomatic because urine flow declines in those with chronic renal failure, it may become symptomatic when urine flow increases after renal transplant. Untreated benign prostate hyperplasia may lead to several complications that adversely affect the kidney allograft. MATERIALS AND METHODS Our retrospective study investigated data from 286 male transplant patients. Data obtained included medical history, clinical examination, prostate-specific antigen, prostate volume, and residual urine volume results. Patients had completed an International Prostate Symptom Score questionnaire to assess the low urinary symptoms. Creatinine level, residual urine volume, International Prostate Symptom Score, and uroflow-metry results were reviewed. RESULTS The average age of patients in our group was 54.8 years. Seven patients were diagnosed with benign prostate hyperplasia, and transurethral resection of the prostate was performed. The average creatinine levels before and after transurethral resection were 2.53 ± 0.76 mg/dL and 1.66 ± 1.12 mg/dL, respectively. Creatinine levels measured 6 months after transurethral resection versus before resection were statistically significant (P < .018). Furthermore, there was a statistically significant difference (P < .017) in the postmicturition residual urine volume between the preoperative and postoperative values, which were 132.14 ± 19.33 and 47.6 ± 18.6 mL, respectively. Maximum urine flow rates before and after transurethral resection were also significantly different (P < .017). CONCLUSIONS Although the main reasons for graft function loss after renal transplant are rejection and infections, obstructive pathologies should also be considered. Especially for elderly patients, anamnesis, uroflowmetry, and digital rectal examination play critical roles in the evaluation of benign prostate hyperplasia before and after transplant.

Abstract
Background The kidney is the most frequently transplanted human organ worldwide. In patients with end-stage renal failure, renal transplantation improves both quality of life and life expectancy. The current literature indicates that the numbers of renal recipients over 60 years of age has increased in recent years. Objectives To evaluate the prevalence and management of lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO) in a contemporary series of male renal transplant (RTx) recipients. Materials and Methods We retrospectively evaluated 150 consecutive transplant recipients at the University of Jena 12 months postoperatively for the presence and treatment of LUTS related to BPO. Results The mean age of the patients was 59 years (range 27 - 82 years). By 12 months postoperatively, 91% (n = 137/150) were off dialysis with a functioning kidney graft. Two patients died during follow up. Six patients had undergone treatment for prostate cancer prior to RTx. Of the remaining 131 patients, 47% (n = 62/131) were considered as patients with BPO 12 months after RTx. Six percent (n = 8/131) of the patients experienced urinary retention due to BPO and 6% (n = 8/131) had a transurethral resection of the prostate (TURP) during the first year after RTx. No major complications were observed in those patients. A significant increase was noted in the use of α-blocker therapy after RTx (P = 0.004). Conclusions We observed a high prevalence of LUTS related to BPO in our cohort of patients. Due to the increasing age of transplant recipients, more attention should be paid to the evaluation and treatment of BPO prior to RTx.

Abstract
OBJECTIVE We investigated lower urinary tract symptoms (LUTS) and function in patients who had undergone renal transplantation (RTx). METHODS Fifty patients (34 males and 16 females; age 16-68 years) undergoing RTx at our hospital were included in this study. Average follow-up after RTx was 6.1 years (range 0.5-28). The pre-transplant dialysis period averaged 2.5 years (range preemptive-18.6 years). We conducted the evaluation of lower urinary tract symptoms (LUTS) and function using uroflowmetry (UFM) , residual urine measurement, 24h bladder diary, International Prostate Symptom Score (IPSS), QOL score, Overactive Bladder Symptom Score (OABSS) and Core Lower Urinary Tract Symptom Score (CLSS). RESULTS Average first desire to void and maximum desire to void were 89.9 mL and 185 mL respectively in cystometry before RTx. Atrophy of the bladder before RTx showed a correlation with the dialysis period. UFM of post-RTx was maximum urinary flow rate of 21.8 mL/s and a voided volume of 287.6 mL. Severe cases of IPSS, QOL, OABSS and CLSS were not observed. Average 24h voided volume, urination times and nocturia were 2,329 mL, 8.2 times and 0.9 times respectively. Polyuria after RTx was observed in 21 patients (42%). Aging and vascular lesions such as diabetes and cardiovascular disease were the most important factor of LUTS. CONCLUSIONS After RTx, LUTS were present in a number of cases after RTx. Patients undergoing RTx has been aging, it is considered necessary to perform the evaluation of LUTS before RTx.

Abstract
BACKGROUND The number of renal transplant recipients is rising, as well as graft and recipient survival. The mainstay of urological follow-up is to ensure urine transport and voiding function; also, the diagnosis and treatment of urological malignancies following renal transplantats is growing in importance. As urological malignancies are one of the three most common tumors following renal transplantation (RT), meticulous and regular urological evaluation is a central part of follow-up care after RT. RECOMMENDATIONS Urological evaluation following RT must ensure correct urine transport and voiding function. Transplant ureter strictures, relevant ureteral reflux and voiding dysfuntion (e.g., neurologic dysfunction, benign prostate hypeplasia) must be excluded or treated. Urinary tract infection (UTI), which can be life threatening in the immunosuppressed transplant recipient, must be diagnosed and treated consequently and for an adequate period of time. Prophylaxis of UTIs is indicated in patients with recurrent symptomatic UTI as well as in the initial 6 months following renal transplantation. Asymptomatic bacteriuria must not necessarily be treated. The incidence of urological malignancies like renal cell carcinoma, urothelial cancer of the bladder, and penile carcinoma is increased following RT, while the incidence of prostate and testis cancer is the same as in the nontransplant population. Surgical and nonsurgical treatment options do not differ from the normal population. Adaptation, cessation, or switching of the immunosuppressive regimen in case of urologic malignancy must be decided on the individual recipient basis.

Abstract
Voiding dysfunction is frequently seen in the early posttransplant period. Among other causes, this condition can arise due to bladder outlet obstruction. Primary bladder neck obstruction (PBNO) is a possible but very rare cause of bladder outlet obstruction. We present the case of a 52-year-old woman who, after kidney transplantation, presented with PBNO. The diagnosis was established based on symptoms, uroflowmetry, and multichannel urodynamics with electromyography. The transurethral incision of the bladder neck was made at the 5- and 7-o'clock position. After the operation, the maximal flow rate was significantly increased, and postvoid residual urine was decreased compared to the preoperative findings. The patient was followed for 5 years, and her voiding improvement is persistent. This is the first reported case of PBNO treated with a transurethral incision of the bladder neck in a posttransplantation female patient.
