“…The incidence of bladder dysfunction was previously reported to be high in patients with renal failure . A hypocompliant bladder (decrease in bladder capacity with increase in intravesical pressure) is the main cystometric abnormality in patients who undergo long‐term dialysis . The results of the present study were comparable with those of the previous study by Turunc et al ., who showed that 68% of patients with pretransplant dialysis duration of >5 years had a pretransplant hypocompliant bladder <10 mL/cmH 2 O .…”

“…5 However, the relationship between bladder dysfunction before transplantation and the occurrence of VUR was not examined in our previous study, because cystometric evaluations were not carried out. 4 Previous studies that carried out urodynamic evaluations in patients with end-stage renal disease or before kidney transplantation [6][7][8][9][10][11] showed that the cystometric bladder capacity and bladder compliance decreased as dialysis duration increased. [9][10][11] A low compliance (hypocompliance) bladder is frequently observed in patients with pretransplant defunctionalized small bladders.…”

Cystometric evaluation of recovery in hypocompliant defunctionalized bladder as a result of long‐term dialysis after kidney transplantation

Bladder compliance decreases logarithmically pretransplantation according to dialysis duration. Although the ability of the patients to recover varies, dysfunctions associated with a pretransplant hypocompliant bladder recover to normal ranges after renal transplantation. A pretransplant hypocompliant bladder seems not to be associated with the post-transplant prevalence of urinary complications or vesicoureteral reflux.

Objectives To investigate factors associated with low-compliance bladders (LCB) in pretransplant patients with end-stage renal disease (ESRD) and develop a clinical prediction model for urodynamic studies. Methods This study was a prospective cohort study. Patients with ESRD on the renal transplantation waiting list were recruited and underwent the urodynamic study. Demographics data, predictor factors related to the bladder compliance such as underlying disease of the lower urinary tract disease (LUTD), duration of urine < 250 mL/day, type and duration of renal replacement therapy (RRT), urine volume per day and urodynamic study information were collected. Univariable and multivariable logistic regression models were used to assess the independence of explanatory factors, then we developed the clinical prediction model. Results One hundred fifty-two patients participated in the study: 94 patients in the normal bladder group and 58 patients in LCB group. Demographic data were not significantly different between the two groups, except diabetes. Cystometric capacity, detrusor pressure, compliance were significantly different. From the univariate analysis, DM status, duration of RRT, and passing < 100 mL of urine per day were related to LCB. We named the prediction model, the DUDi score based on the predictors ( D uration of RRT, U rine volume/day, Di abetes). Higher scores predicted a higher risk of low-compliance bladder [ P value = 0.464 according to the Hosmer–Lemeshow test, and the AUC was 0.87 (95% CI 0.81–0.92)]. Conclusions Our clinical prediction model is easy to use and provides a high predictive value that is appropriate for patients who have no known LUTD to identify low-compliance bladder. Trial registration number and date of registration for prospectively registered trials This study was approved by the Thai Clinical Trials Registry Committee on 09 February 2021. The TCTR identification number is TCTR20210209006.

Purpose of Review Urodynamic testing (UDS) is a valuable tool for understanding the safety of the lower urinary tract (LUT). The goal of this review is to provide evidence-based indications for use of UDS in both the pre-and post-kidney transplant (KT) settings. Recent Findings Pre-transplant bladder cycling with UDS for anuric or oliguric patients is no longer recommended. Instead, UDS aids in identifying LUT anomalies that may require optimization prior to transplant, especially in patients with known urologic etiologies of end-stage renal disease (ERSD). In pre-KT patients with recurrent urinary tract infections (UTIs) or prior urologic/pelvic interventions, UDS should be used judiciously when the etiology of LUT dysfunction is unclear. In the post-transplant setting, urologists are often consulted for LUT symptoms (LUTS), hydronephrosis, urinary retention, declining renal function, and most commonly, recurrent UTI. Again, UDS should not be routinely performed first line, but as an adjunct to distinguish similarly presenting LUT etiologies such as bladder outlet obstruction (BOO) and bladder dysfunction. Summary UDS remains the gold standard for characterizing the LUT, and when utilized appropriately, can identify factors promoting graft and patient survival after KT.

Evaluation of video-urodynamic studies before renal transplantation in chronic renal failure patients

Abstract: Video-urodynamic studies before renal transplantation provide earlier diagnosis of lower tract abnormalities, which are likely to cause graft dysfunction.
