“…The operator was consistently able to identify and evaluate anatomical landmarks and to assess their change during the two maneuvers. MUL is one of the few measurements to have an established predictive role for post‐operative recovery of continence, 13 and we show MUL can be readily assessed with TPUS and with no significant difference in measurements compared with the reference standard of mpMRI. Likewise, pre‐operative intravesicular protrusion of the prostate has shown promise as a predictive measure 23 , 24 and could be assessed by TPUS with comparable results to MRI.…”

“…Although mp-MRI has become the leading imaging technique for the detection, preoperative staging, and risk-stratification of prostate cancer, 2,11,12 only limited research has been undertaken for predictive features of PPUI in the preoperative setting. 13 Transperineal ultrasound (TPUS) is a noninvasive tool that has been widely used in the evaluation of female urinary incontinence and functional disorders of the pelvic floor, 14,15 however only limited studies have applied this technique for evaluation of the male pelvic floor. 16,17 TPUS has emerged as a functional imaging technique that could allow the dynamic evaluation of proximal urethral mobility and the pelvic floor in prostatectomy patients; however, its utility is yet to be studied in the combined pre and post-operative settings.…”

“…The widespread use of pre‐operative multiparametric magnetic resonance imaging (mp‐MRI) 10 and recent advances in ultrasound technology have made imaging a feasible and attractive means of assessing pre‐ and post‐operative changes in both the prostatic bed and the pelvic floor. Although mp‐MRI has become the leading imaging technique for the detection, pre‐operative staging, and risk‐stratification of prostate cancer, 2,11,12 only limited research has been undertaken for predictive features of PPUI in the pre‐operative setting 13 …”

This study assessed the feasibility of dynamic transperineal ultrasound (TPUS) pre/post-radical prostatectomy (RP). Ninety-eight patients were scanned preoperatively and at four time-points post-operatively. TPUS was performed in 98 patients using an abdominal transducer at rest, during pelvic floor contraction (PFC) and Valsalva (VS) maneuver in supine and standing positions. Urodynamic evaluations included bladder neck angle at rest/PFC/VS, and degree of bladder neck movement. Pre-operative and post-operative measurements were technically feasible in >85% (supine) and >90% (standing) of patients. TPUS offers a reliable non-invasive dynamic assessment of the pelvic floor post-prostatectomy and may prove a useful adjunct for guiding exercises to preserve continence.

Purpose To evaluate the predictors for short and long term urinary continence (UC) recovery after laparoscopic radical prostatectomy (LRP) from clinical and oncological variables. Methods We retrospectively collected data from 142 prostate cancer patients who underwent LRP between September 2014 and June 2021 at a tumor specialist diagnosis and treatment center in China. The rate of post-prostatectomy incontinence (PPI) was evaluated from final rehabilitation reports after catheter extraction and at 3, 6 and 12 mo after LRP, and UC was defined as the use of no or one safety pad. Eighteen clinical and oncological variables were analyzed by univariate and multivariate regression analysis to determine whether they were associated with short (3 mo) or long term (12 mo) UC recovery after LRP. Results After eliminating patients who were lost to follow-up, 129 patients were eventually included. The mean ± SD age was 68 ± 6.3 years. The UC rates of immediate catheter removal, 3, 6 and 12 mo after the operation were 27.9%, 54.3%, 75.2% and 88.4%, respectively. Multivariate analyses revealed that membranous urethral length (MUL) was a protective predictor of UC after catheter extraction [odds ratio (OR) 1.77; 95% confidence interval (CI) 1.37–2.28; P < 0.001], and at 3 mo (OR 2.25; 95% CI 1.63–3.10; P < 0.001), 6 mo (OR 1.47; 95% CI 1.20–1.80; P < 0.001) and 12 mo (OR 1.50; 95% CI 1.11–2.04; P = 0.009) after surgery. Conclusion MUL is a significant independent factor that can contribute to recovery of short and long term UC recovery post-LRP, which may assist clinicians and their patients in counseling of treatment. .

Objectives The purpose of this study was to investigate intraductal carcinoma of the prostate (intraductal carcinoma) and significant cancer (SC) in patients with small tumor volume (<0.5 cm3) in prostatectomy specimens. Methods Data from 639 patients undergoing radical prostatectomy between April 2006 and December 2017 at Chiba University Hospital and 2 affiliated institutions were retrospectively reviewed. Tumor volume in prostatectomy specimens was measured, and with a tumor volume of less than 0.5 cm3, the presence of intraductal carcinoma and SC was examined. SC was defined as one that did not meet the definition of pathological insignificant cancer (organ‐confined cancer, Grade Group 1, tumor volume < 0.5 cm3). The number of patients who met four active surveillance (AS) protocols was also examined. Results A total of 83 patients with tumor volume < 0.5 cm3 were identified in this study population (SC: 43 patients [52%], intraductal carcinoma: 5 patients [6%]). The median follow‐up was 34.6 months (range: 18–57 months). Four (5%) developed biochemical recurrence. The number of positive biopsy cores ≥ 2 was an independent predictor of SC in patients with tumor volume < 0.5 cm3 (hazard ratio: 4.39; 95% confidence interval: 1.67–11.56; p = 0.003). In tumor volume < 0.5 cm3, tumor volume was significantly correlated with the International Society of Urological Pathology Grade Group (1 vs. 4–5, p = 0.002) and the presence of intraductal carcinoma (p = 0.004). In intraductal carcinoma‐positive cases, four of five patients (80%) had the predictor of SC, which was two or more positive biopsy cores. Of the four AS protocols, the criteria for Prostate Cancer Research International: Active Surveillance were met most frequently in 46 cases (55%) of tumor volume less than 0.5 cm3 if targeted biopsy by magnetic resonance imaging was available. Conclusion The results of the present study suggest that intraductal carcinoma was present even in cases with small tumor volumes. Grade Group and intraductal carcinoma showed a positive correlation with tumor volume.
