Background: Since January 2018 performance of urethroplasties is done on regular basis at the University Hospital Frankfurt (UKF). We aimed to implement and transfer an institutional standardized perioperative algorithm for urethral surgery (established at the University Hospital Hamburg-Eppendorf—UKE) using a validated Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM) in patients undergoing urethroplasty at UKF. Materials and Methods: We retrospectively analyzed all patients who underwent urethroplasty for urethral stricture disease between January 2018 and January 2020 at UKF. All patients were offered to revisit for clinical follow-up (FU) and completion of USS-PROM. Primary end point was stricture recurrence-free survival (RFS). Secondary endpoints were functional outcomes, quality of life (QoL), and patient satisfaction. Results: In total, 50 patients underwent urethroplasty and 74 and 24% had a history of previous urethrotomy or urethroplasty, respectively. A buccal mucosal graft urethroplasty was performed in 86% (n = 43). After patient's exclusion due to lost of FU, FU <3 months, and/or a pending second stage procedure, 40 patients were eligible for final analysis. At median FU of 10 months (interquartile-range 5.0–18.0), RFS was 83%. After successful voiding trial, the postoperative median Qmax significantly improved (24.0 vs. 7.0 mL/s; p < 0.01). Conversely, median residual urine decreased significantly (78 vs. 10 mL; p < 0.01). Overall, 95% of patients stated that QoL improved and 90% were satisfied by the surgical outcome. Conclusions: We demonstrated a successful implementation and transfer of an institutional standardized perioperative algorithm for urethral surgery from one location (UKE) to another (UKF). In our short-term FU, urethroplasty showed excellent RFS, low complication rates, good functional results, improvement of QoL and high patient satisfaction. PROMs allow an objective comparison between different centers.

Objectives: Bladder neck contracture (BNC) is a bothersome complication following endoscopic treatment for benign prostatic hyperplasia (BPH). The objective of our study was to give a more realistic insight into contemporary endoscopic BNC treatment and to evaluate and identify risk factors associated with inferior outcome. Material and Methods: We identified patients who underwent transurethral treatment for BNC secondary to previous endoscopic therapy for BPH between March 2009 and October 2016. Patients with vesico-urethral anastomotic stenosis after radical prostatectomy were excluded. Digital charts were reviewed for re-admissions and re-visits at our institutions and patients were contacted personally for follow-up. Our non-validated questionnaire assessed previous urologic therapies (including radiotherapy, endoscopic, and open surgery), time to eventual further therapy in case of BNC recurrence, and the modality of recurrence management. Results: Of 60 patients, 49 (82%) and 11 (18%) underwent transurethral bladder neck resection and incision, respectively. Initial BPH therapy was transurethral resection of the prostate (TURP) in 54 (90%) and holmium laser enucleation of the prostate (HoLEP) in six (10%) patients. Median time from prior therapy was 8.5 (IQR 5.3–14) months and differed significantly in those with (6.5 months; IQR 4–10) and those without BNC recurrence (10 months; IQR 6–20; p = 0.046). Thirty-three patients (55%) underwent initial endoscopic treatment, and 27 (45%) repeated endoscopic treatment for BNC. In initially-treated patients, time since BPH surgery differed significantly between those with a recurrence (median 7.5 months; IQR 6–9) compared to those treated successfully (median 12 months; IQR 9–25; p = 0.01). In patients with repeated treatment, median time from prior BNC therapy did not differ between those with (4.5 months; IQR 2–12) and those without a recurrence (6 months; IQR 6–10; p = 0.6). Overall, BNC treatment was successful in 32 patients (53%). The observed success rate of BNC treatment was significantly higher after HoLEP compared to TURP (100% vs. 48%; p = 0.026). Type of BNC treatment, number of BNC treatment, and age at surgery did not influence the outcome. Conclusions: A longer time interval between previous BPH therapy and subsequent BNC incidence seems to favorably affect treatment success of endoscopic BNC treatment, and transurethral resection and incision appear equally effective. Granted the relatively small sample size, BNC treatment success seems to be higher after HoLEP compared to TURP, which warrants validation in larger cohorts.

Objective: We aimed to assess the correlation between serum prostate-specific antigen (PSA) and tumor burden in prostate cancer (PCa) patients undergoing radical prostatectomy (RP), because estimation of tumor burden is of high value, e.g., in men undergoing RP or with biochemical recurrence after RP. Patients and Methods: From January 2019 to June 2020, 179 consecutive PCa patients after RP with information on tumor and prostate weight were retrospectively identified from our prospective institutional RP database. Patients with preoperative systemic therapy (n=19), metastases (cM1, n=5), and locally progressed PCa (pT4 or pN1, n=50) were excluded from analyses. Histopathological features, including total weight of the prostate and specific tumor weight, were recorded by specialized uro-pathologists. Linear regression models were performed to evaluate the effect of PSA on tumor burden, measured by tumor weight after adjustment for patient and tumor characteristics. Results: Overall, median preoperative PSA was 7.0 ng/ml (interquartile range [IQR]: 5.41–10) and median age at surgery was 66 years (IQR: 61-71). Median prostate weight was 34 g (IQR: 26–46) and median tumor weight was 3.7 g (IQR: 1.8–7.1), respectively. In multivariable linear regression analysis after adjustment for patients and tumor characteristics, a significant, positive correlation could be detected between preoperative PSA and tumor weight (coefficient [coef.]: 0.37, CI: 0.15–0.6, p=0.001), indicating a robust increase in PSA of almost 0.4 ng/ml per 1g tumor weight. Conclusion: Preoperative PSA was significantly correlated with tumor weight in PCa patients undergoing RP, with an increase in PSA of almost 0.4 ng/ml per 1 g tumor weight. This might help to estimate both tumor burden before undergoing RP and in case of biochemical recurrence.

Introduction: MRI-targeted biopsy (TB) increases overall prostate-cancer (PCa) detection-rates and decreases the risk of insignificant PCa detection. However, the impact of these findings on the definite pathology after radical prostatectomy (RP) is under debate. Materials and Methods: Between 01/2014 and 12/2018, 366 patients undergoing prostate biopsy and RP were retrospectively analyzed. The correlation between biopsy Gleason-score (highest Gleason-score in a core) and the RP Gleason-score in patients undergoing systematic biopsy (SB-group) (n = 221) or TB+SB (TB-group, n = 145) was tested using the ISUP Gleason-group grading (GGG, scale 1–5). Sub analyses focused on biopsy GGG 1 and GGG ≥ 2. Results: Proportions of biopsy GGG 1–5 in the SB-group and TB-group were 24.4, 37.6, 19, 10.9, 8.1% and 13.8, 43.4, 24.2, 13.8, 4.8%, respectively (p = 0.07). Biopsy and pathologic GGG were concordant in 108 of 221 (48.9%) in SB- and 74 of 145 (51.1%) in TB-group (p = 0.8). Gleason upgrading was recorded in 33.5 and 31.7% in SB- vs. TB-group (p = 0.8). Patients with biopsy GGG 1 undergoing RP showed an upgrading in 68.5%(37/54) in SB- and 75%(15/20) in TB-group (p = 0.8). In patients with biopsy GGG ≥ 2 concordance increased for both biopsy approaches (54.5 vs. 55.2% for SB- vs. TB-group, p = 0.9). Discussion: Irrespective of differences in PCa detection-rates between TB- and SB-groups, no significant differences in GGG concordance and upgrading between patients of both groups undergoing biopsy, followed by RP, were recorded. Concordance rates increased in men with biopsy GGG ≥ 2. TB seems to detect more patients with PCa without a difference in concordance with final pathology.
