[Urinary stress incontinence in men: diagnostic workup and modern surgical treatment]. / Belastungsinkontinenz des Mannes: sinnvolle Diagnostik und moderne operative Therapie.

Radical prostatectomy is the most common cause of urinary stress incontinence in male patients. The exact pathophysiology is not clearly defined but probably due multifactorial. Thorough preoperative diagnostic workup before surgical therapy appears to be crucial for good postoperative results. Various systems are available. The artificial urinary sphincter continues to be considered standard procedure with a high success rate, even in patients with more complex situations and severe urinary incontinence. However, there are also relevant complication and revision rates. Modern alternatives include various sling systems. The adjustable sling systems consist of a cushion that is placed against the urethral bulb and leads to a permanent increase in urethral resistance, which can be readjusted in different ways depending on the system implanted. The adjustable sling systems also seem to be an alternative in patients with a prior history of radiation therapy. The AdVance XP sling (Boston Scientific, Marlborough, MA, USA) is a fixed sling that corrects the postoperative hypermobility of the posterior urethra after radical prostatectomy and, thus, leads to a longer functional urethral length. Good long-term results after AdVance XP implantation are only possible in selected patients.

Optimizing Nerve Sparing in Robotic-Assisted Radical Prostatectomy: A Comparative Investigation of Traditional and Modified Endopelvic Fascia Preservation Techniques.

Background: Prostate cancer (PCa) is the second most common cancer and the sixth leading cause of cancer-related mortality in men. In 2000, Abbou performed the first robot-assisted radical prostatectomy, and radical prostatectomy has developed rapidly. Robot-assisted radical prostatectomy (RARP) is a valuable therapeutic option for the management of localized Pca. Objective: To present the functional outcome of robot-assisted laparoscopic radical prostatectomy using traditional and modified endopelvic fascia preservation methods in a single center in Vietnam. Methods: We prospectively analyzed a series of 65 patients diagnosed with prostate cancer from 2020 to 2023. All of those were operated by DaVinci Si system robot-assisted laparoscopic prostatectomy. Twenties patients were applied with a modified nerve-sparing technique, intrafascial dissection, and lateral prostatic fascia preservation, leaving the lateral tissue, including the neurovascular bundle, untouched and covered. We used the traditional approach, intrafascial nerve-sparing with open endopelvic fascia and lateral prostatic fascia in 45 cases. Patients were followed up to 12 months to assess the continence and erectile function by using IIEF-5 and EPIC questionnaires. Results: The study sample included 65 cases; the mean patient age was 64.21 ± 6.68, erection rate after surgery at six months in bilateral NS was 36.58% (15/41) in the traditional group, and 68.42% (13/19) in the modified group (p=0.028). The patient did not recover erectile ability in the group of elderly patients (>65 years old) and unilateral nerve-sparing group. The continence rate six months after surgery was 86.66 % in the conventional group and 85% in the modified group, with no significant difference between the two groups. In the potency group, the IIEF-5 score was 13 ± 4.9, and the EPIC-26 score was 62.20 ± 10.04. Erectile ability in the modified group was better than the traditional group at six months after surgery. Conclusion: Our results showed better potency recovery in the modified group. These results should be tested in future research with randomized studies.

Transvesical robot-assisted radical prostatectomy: a report of 13 cases / 现代泌尿外科杂志

【Objective】 To share the technical key points and experience of transvesical robot-assisted radical prostatectomy (TvRARP). 【Methods】 The clinical data of 13 patients with prostate cancer (PCa) receiving TvRARP during Nov.2021 and May 2022 were collected. The operation time, estimated blood loss, blood transfusion rate, catheter removal time, postoperative length of hospital stay, immediate urinary continence rate, postoperative IIEF-5 score and perioperative complications were evaluated. 【Results】 The operation time was (142±39) min, estimated intraoperative blood loss was (76±40) mL, and no transfusion was needed. The median postoperative IIEF-5 score was 16 (12-22), hospital stay 3 (2-5)days, and catheter removal time 7(5-14)days. Of all 13 patients, 12(92.3%) achieved immediate urinary continence at the removal of catheter. There were no postoperative complications of Clavien Ⅲ and above. Clavien Ⅰ-Ⅱ complications were observed in 4 patients (30.8%). 【Conclusion】 TvRARP is feasible and safe for selected patients with clinically localized PCa, which can ensure promising postoperative urinary continence and preserve erectile functional.

Cytoreductive radical prostatectomy after chemohormonal therapy in patients with primary metastatic prostate cancer.

OBJECTIVE: Cytoreductive radical prostatectomy (cRP) has been proposed as local treatment option in metastatic hormone-sensitive prostate cancer (mHSPC) to prevent local complications and potentially improve oncological outcomes. In this study, we examined the feasibility of a multimodal concept with primary chemohormonal therapy followed by cRP and analyzed prostate size reduction under systemic treatment, postoperative complication rates, as well as early postoperative continence. METHODS: In this retrospective study, 38 patients with mHSPC underwent cRP after primary chemohormonal therapy (3-monthly luteinising hormone-releasing hormone-analogue + six cycles 3-weekly docetaxel 75 mg/m2) at two centers between September 2015 and December 2018. RESULTS: Overall, 10 (26%) patients had high volume and 28 (74%) patients had low volume disease at diagnosis, according to CHAARTED definition. Median prostate-specific antigen (PSA) decreased from 65 ng/mL (interquartile range [IQR] 35.0-124.5 ng/mL) pre-chemotherapy to 1 ng/mL (IQR 0.3-1.7 ng/mL) post-chemotherapy. Prostate gland volume was significantly reduced by a median of 50% (IQR 29%-56%) under chemohormonal therapy (p = 0.003). Postoperative histopathology showed seminal vesicle invasion in 33 (87%) patients and negative surgical margins in 17 (45%) patients. Severe complications (Grade 3 according to Clavien-Dindo) were observed in 4 (11%) patients within 30 days. Continence was reached in 87% of patients after 1 month and in 92% of patients after 6 months. Median time to castration-resistance from begin of chemohormonal therapy was 41.1 months and from cRP was 35.9 months. Postoperative PSA-nadir ≤1 ng/mL versus >1 ng/mL was a significant predictor of time to castration-resistance after cRP (median not reached versus 5.3 months; p<0.0001). CONCLUSION: We observed a reduction of prostate volume under chemohormonal therapy going along with a low postoperative complication and high early continence rate. However, the oncologic benefit from cRP is still under evaluation.

The therapeutic effect of pelvic floor muscle exercise on urinary incontinence after radical prostatectomy: a meta-analysis.

Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). However, whether the PFME guided by a therapist (G-PFME) can contribute to the recovery of urinary continence for patients after RP is still controversial. We performed this meta-analysis to investigate the effectiveness of G-PFME on UI after RP and to explore whether the additional preoperative G-PFME is superior to postoperative G-PFME alone. Literature search was conducted on Cochrane Library, Embase, Web of Science, and PubMed, to obtain all relevant randomized controlled trials published before March 1, 2018. Outcome data were pooled and analyzed with Review Manager 5.3 to compare the continence rates of G-PFME with control and to compare additional preoperative G-PFME with postoperative G-PFME. Twenty-two articles with 2647 patients were included. The continence rates of G-PFME were all superior to control at different follow-up time points, with the odds ratio (OR) (95% confidence interval [CI]) of 2.79 (1.53-5.07), 2.80 (1.87-4.19), 2.93 (1.19-7.22), 4.11 (2.24-7.55), and 2.41 (1.33-4.36) at 1 month, 3 months, 4 months, 6 months, and 12 months after surgery, respectively. However, there was no difference between additional preoperative G-PFME and postoperative G-PFME, with the OR (95% CI) of 1.70 (0.56-5.11) and 1.35 (0.41-4.40) at 1 month and 3 months after RP, respectively. G-PFME could improve the recovery of urinary continence at both early and long-term stages. Starting the PFME preoperatively might not produce extra benefits for patients at early stage, compared with postoperative PFME.

Tiempo quirúrgico promedio 33 minutos (15-70). Días promedio de hospitalización 1,09 (1-3).Residuo posmiccional promedio 39,3 cc. Complicaciones: Perforación vesical 14 (13 por ciento),retención urinaria 3 (3 por ciento), ITU aguda no complicada 1 (1 por ciento), infección de herida operatoria1 (1 por ciento). La tasa de continencia con pacientes secas sin uso de protectores fue de 83 por ciento. En 12 pacientes (11 por ciento) se desarrolló una urgencia miccional de novo, la que ha sido manejada en forma satisfactoria con anticolinérgicos. Discusión: Podemos concluir que la técnica de sling retropúbico es un procedimiento con buenos resultados a largo plazo, mínimamente invasiva y con una tasa de complicaciones aceptables que pueden habitualmente ser resueltas sin mayores problemas en la práctica clínica habitual del urólogo. Los resultados son además concordantes con otras series tanto nacionales como internaciones.

Introduction: The aim of this paper is to show the long-term results of TVT technique with minimal follow-up of 6 years. Materials and methods: With local manufacturing devices and using the technique of TVT, 108 patients were operated between January2002 and August 2003. The data analyzed were age, parity, previous surgery, nutritional status, surgical time, Foley catheter and hospital stay, post void residual urine, complications and urinary continence. Results: Median age 53 years (27-76). Mean follow-up time 80 months (72-90). Mean body mass index 29, mean parity 3.5. Mean operative time 33 minutes (15-70). Mean hospital days 1.09 (1-3). Mean post void residual urine 39.3 cc. Complications: bladder perforation 14 (13 percent), urinary retention, 3 (3 percent), uncomplicated urinary tract infection 1 (1 percent), wound infection 1 (1 percent). The continence rate with dry patients was 83 percent. 12 patients (11 percent) developed de novo urgency, which has been satisfactorily treated with anticholinergics. Discussion: We conclude that retropubic sling is a procedure with successful long-term results, minimally invasive, with acceptable complications that can usually be resolved without problems in clinical practice by urologist. The results are also consistent with other series both national and international.
