Comparison of urinary incontinence following three different prostate apex disconnection techniques in transurethral thulium laser prostatectomy.

OBJECTIVE: This study investigates the incidence of urinary incontinence following transurethral thulium laser prostatectomy with three different prostate apex disconnection techniques: semi-separation, pre-separation, and post-separation. The findings aim to provide references for clinical treatment. PATIENTS AND METHODS: A retrospective analysis was conducted on 74 patients treated with transurethral thulium laser prostatectomy for prostatic hyperplasia from April 2022 to March 2023. Complete clinical and follow-up data were available for 52 patients. Clinical and follow-up data were collected for these patients. A comparison was made of urinary incontinence following the three different types of prostate apex disconnection in transurethral thulium laser prostatectomy. RESULTS: In this study, the immediate postoperative urinary incontinence rate for transurethral thulium laser prostatectomy was 9.62% (5/52), the short-term incontinence rate was 11.54% (5/52), and the long-term incontinence rate was 9.62% (5/52). The immediate postoperative incontinence rates for semi-separation, pre-separation, and post- separation were 8.33% (1/12), 8.33% (2/24), and 12.5% (2/16), respectively. The short-term incontinence rates for semi-separation, pre-separation, and post-separation were 8.33% (1/12), 8.33% (2/24), and 18.75% (3/16), respectively. The long-term incontinence rates for semi-separation, pre-separation, and post-separation were 8.33% (1/12), 8.33% (2/24), and 12.5% (2/16), respectively. CONCLUSIONS: The incidence of urinary incontinence following transurethral thulium laser prostatectomy was lower with semi-separation and pre-separation compared to post-separation.

Patients experience with the use of a penile clamp in post-prostatectomy incontinence - a prospective pilot study.

OBJECTIVES: The aim of this study was to assess the efficacy of a penile clamp in managing urinary incontinence (UI) and its impact on perceived quality of life (QoL) amongst post-prostatectomy patients. MATERIAL AND METHODS: A prospective pilot study was conducted including patients with post-prostatectomy UI treated with a penile clamp. Inclusion criteria consisted of UI after radical prostatectomy, good hand function, full cognitive function and a minimum penile length of 3 cm and a circumference of 5 cm. An appropriately sized penile clamp was selected during the first visit, and patients were given instructions on how to use it. The first follow-up was a scheduled phone call 1 week after the initial visit. Formal evaluations were performed prior to use of the penile clamp and again after 3 months of usage. These consisted of weighing pads during the daytime with evaluation of leakage, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), incontinence-QoL (I-QoL) and a questionnaire specific for the penile clamp. RESULTS: There were 22 patients included, and two were excluded due to reduced hand function and surgery before the study endpoint. The results showed a significant median reduction of urinary leakage of 57% at rest and 58% during physical activity. One complication was observed, as one patient developed a pinching ulcer, after extensive usage. ICIQ-SF showed an increase of 6% for the included patients (n = 20). Ten patients were satisfied with the clamp, and 15 would recommend the clamp to others. CONCLUSION: The penile clamp shows promising results in reducing leakage with minimal risks of complications. It can be used as a treatment for patients awaiting surgery. However, patient selection is important regarding hand function, cognitive function and the penile anatomy.

Association between 3D membranous urethral parameters and urinary continence recovery after RARP.

OBJECTIVES: To evaluate whether the urinary continence (UC) recovery after robotic-assisted radical prostatectomy (RARP) relates to the membranous urethral length (MUL) and the membranous urethral complex volume (MUV). MATERIALS AND METHODS: 120 patients who underwent RARP were enrolled according to the different times of UC recovery and examined using prostate magnetic resonance imaging (MRI) before surgery. The membranous urethral (MU) parameters were measured using the three-Dimensional (3D) model reconstructed by holographic technology, such as total MUV (tMUV), exposed MUV (eMUV), full MUL (fMUL) and exposed MUL (eMUL). Statistical software SPSS 26.0 was used to analyze the data and compare the MU parameters and baseline data in different groups. RESULTS: Patients with larger tMUV (p = 0.038), eMUV (p = 0.003), longer fMUL (p = 0.025), eMUL (p = 0.044) had better UC after removal of the catheter, and eMUV (OR = 1.002, 95%CI = 1.001-1.004, p = 0.004) was a predictor; the patients with younger age (p = 0.021), lower VPSS score (p = 0.004) and larger eMUV (p = 0.012) and longer eMUL (p = 0.049) had better UC recovery one month after RARP while eMUV (OR = 1.002, 95% CI = 1.000-1.003, p = 0.008) and VPSS score (OR = 0.886, 95% CI = 0.806-0.973, p = 0.011) were independent risk factors; The patients with younger age (p = 0.018), larger tMUV (p = 0.029), eMUV (p = 0.016) had better UC recovery three months after RARP. eMUV (OR = 1.002, 95% CI = 1.000-1.004, p = 0.042) and age (OR = 0.904, 95% CI = 0.818-0.998, p = 0.046) were independent risk factors. CONCLUSION: This clinical study shows that patients with larger MUV and longer MUL can return to UC earlier after surgery. Among that, eMUV is a better predictor.

Impacts of Perioperative Comprehensive Nursing Intervention on Postoperative Urinary Incontinence and Quality of Life of Patients Undergoing Laparoscopic Radical Prostatectomy.

To evaluate the impact of perioperative comprehensive nursing intervention on postoperative urinary incontinence, various aspects of patient well-being were assessed. The comprehensive group, that received the nursing intervention, demonstrated significant improvements in self-care skills, health knowledge level, self-care responsibility, and self-concept compared to the standard group. The findings indicate that perioperative comprehensive nursing intervention has a remarkable effect on patients undergoing laparoscopic radical prostatectomy. This nursing intervention not only effectively improves postoperative urinary incontinence and alleviates negative emotions, such as anxiety and depression. Therefore, the implementation of this nursing intervention model is highly recommended for clinical practice and wider application.

Incidence of complications and urinary incontinence following endoscopic enucleation of the prostate in men with a prostate volume of 80 ml and above: results from a multicenter, real-world experience of 2512 patients.

PURPOSE: To evaluate complications and urinary incontinence (UI) after endoscopic enucleation of the prostate (EEP) stratified by prostate volume (PV). METHODS: We retrospectively reviewed patients with benign prostatic hyperplasia who underwent EEP with different energy sources in 14 centers (January 2019-January 2023). INCLUSION CRITERIA: prostate volume ≥ 80 ml. EXCLUSION CRITERIA: prostate cancer, previous prostate/urethral surgery, pelvic radiotherapy. PRIMARY OUTCOME: complication rate. SECONDARY OUTCOMES: incidence of and factors affecting postoperative UI. Patients were divided into 3 groups. Group 1: PV = 80-100 ml; Group 2 PV = 101-200 ml; Group 3 PV > 200 ml. Multivariable logistic regression analysis was performed to evaluate independent predictors of overall incontinence. RESULTS: There were 486 patients in Group 1, 1830 in Group 2, and 196 in Group 3. The most commonly used energy was high-power Holmium laser followed by Thulium fiber laser in all groups. Enucleation, morcellation, and total surgical time were significantly longer in Group 2. There was no significant difference in overall 30-day complications and readmission rates. Incontinence incidence was similar (12.1% in Group 1 vs. 13.2% in Group 2 vs. 11.7% in Group 3, p = 0.72). The rate of stress and mixed incontinence was higher in Group 1. Multivariable regression analysis showed that age (OR 1.019 95% CI 1.003-1.035) was the only factor significantly associated with higher odds of incontinence. CONCLUSIONS: PV has no influence on complication and UI rates following EEP. Age is risk factor of postoperative UI.

Iatrogenic or recurrent bladder neck contracture treated by the Palminteri-Ferrari technique: a new way to approach a frustrating condition.

PURPOSE: Bladder neck stricture (BNS) is a bothersome disease which may affect patients after trauma or prostatic surgery. It is frustrating due to the low durable success rate of currently available surgical techniques. The aim of the study is to explore the efficacy of a novel technique. MATERIALS & METHODS: The surgical protocol was developed by two high case-volume surgeons. The technique consists of Holmium laser incisions at 3-6-9-12 o'clock. Subsequently, triamcinolone acetonide 40 mg is injected. Two months later, the BNS is endoscopically checked in operatory room and re-procedure take place, if necessary (max 3 times). Failure was defined as the need of definitive urinary diversion. Subjective satisfaction was measured through PGI-I Questionnaire. RESULTS: A total of 45 patients were enrolled. Median age was 63 (IQR 59-69) years and BNS developed by different causes. Naïve BNS procedure patients were 12 (26.7%), others 33 (73.3%) underwent median 2 (IQR 1-4) previous urethrotomies, including 16 other surgeries. Suprapubic bladder catheter was present in 34 patients (75.6%). No complications were registered. Re-procedure at control was necessary in 24 patients (53.3%) for a median of 1 (IQR 1-3) procedures. At median follow-up of 18 months, failures were 4 (8.9%) and urinary incontinence was reported in 2 patients (4.5%) who required incontinence surgery. Median PGI-I was 2. CONCLUSIONS: Our technique of BNS treatment allows good outcomes and high rate of subjective improvement amongst patients. Moreover, naïve patients seem to have better results. However, longer follow-up and higher sample size are mandatory to further assess these data.

Improved early continence following laparoscopic radical prostatectomy: the urethral hammock technique.

PURPOSE: To introduce and illustrate a novel urethral reconstruction technique-the 'urethral hammock-technique'-and to assess its impact on early postoperative continence following laparoscopic radical prostatectomy (LRP). METHODS: 119 patients who underwent LRP between January 2020 and May 2022 (hammock group: n = 43, control group: n = 76) were included in the study. The primary outcome was continence (zero pads or max. one security pad) at 1, 3, and 6 months following surgery. Secondary outcomes were operative time, complications, and histological findings. Univariate and multivariate regression analyses were performed to reveal predictors for continence. p values < 0.05 with a two-sided 95%-confidence interval were considered statistically significant. RESULTS: Baseline characteristics were comparable among both groups. The number of patients achieving complete continence in both the hammock and control groups at various time intervals was: 4 weeks 37.2% (16/43) vs. 19.2% (14/73) (p = 0.047); 3 months 60.5% (26/43) vs. 37.3% (28/75) (p = 0.021) and 6 months 72.1% (31/43) vs. 60.3% (44/73) (p = 0.23), respectively. Adjusting for bladder neck preservation status and age, the hammock technique was a significant predictor for continence for the 4-week (OR 0.33, 95% CI 0.13-0.83, p = 0.019) and 3-month (OR 0.28, 95% CI 0.12-0.66, p = 0.004) interval but not for the 6-month interval (OR 0.64, 95% CI 0.27-1.5, p = 0.31). Operative time, complication rates, time till catheter extraction and histological findings were comparable between both groups (all p > 0.05). CONCLUSIONS: The hammock technique is a simple and reproducible technique to improve early postoperative continence for at least 3 months following surgery. However, these promising results warrant confirmation through a randomized controlled trial.

Control4Life: A randomized controlled trial protocol examining the feasibility and efficacy of a combined pelvic health rehabilitation and exercise fitness program for individuals undergoing prostatectomy.

BACKGROUND: Urinary incontinence (UI), erectile dysfunction and cardiometabolic conditions are common after prostatectomy for prostate cancer (PCa). Although physical activity could improve overall survival and quality of survivorship, fear of UI can restrict participation in exercise. Individuals with PCa could benefit from therapeutic exercise programming to support continence recovery and cardiometabolic health. AIM: The main objective of this study is to determine the feasibility and the effects of a combined pelvic health rehabilitation and exercise fitness program on UI after prostatectomy. The combined exercise program will be delivered both in-person and virtually. METHODS: This study follows a modified Zelen, two-arm parallel randomized controlled trial design. A total of 106 individuals with PCa will be recruited before prostatectomy surgery. Participants will be randomized between two groups: one receiving usual care and one receiving a combined exercise fitness and intensive pelvic floor muscle training program. Exercise programming will begin 6-8 weeks after prostatectomy and will last 12 weeks. Outcomes include: the 24-h pad test (primary outcome for UI); physical fitness, metabolic indicators, and patient-reported outcomes on erectile function, self-efficacy, severity of cancer symptoms and quality of life. Important timepoints for assessments include before surgery (T0), after surgery (T1), after intervention (T3) and at one-year after surgery (T4). CONCLUSION: This study will inform the feasibility of offering comprehensive exercise programming that has the potential to positively impact urinary continence, erectile function and cardiometabolic health of individuals undergoing prostatectomy for prostate cancer.

Retzius-sparing vs. posterior urethral suspension: similar early-phase post-robotic radical prostatectomy continence outcomes.

Stress urinary incontinence (SUI) is a risk of robotic-assisted radical prostatectomy (RP) which can be a frustrating problem for both surgeons and patients. We aim to compare short-term continence outcomes between patients undergoing Retzius Sparing RP (RS-RP) and those undergoing standard RP with the inclusion of a PUS suture technique and suprapubic tube (PUS-RP). A retrospective review of 105 consecutive patients who underwent RP was performed, comparing patients who underwent RS-RP and PUS-RP. Our main outcome was pad usage as a surrogate for SUI. Patients were evaluated 4 weeks following RP and again at approximately 3 months. Continence was defined as no pad usage or up to one safety pad per day. Risk factors associated with not being continent were identified using univariate and multivariate analyses. In our cohort, 52 patients underwent RS-RP and 53 patients underwent PUS-RP. The two groups had similar patient demographics. Although not statistically significant, there was a higher rate of a positive surgical margin in the RS-RP compared to PUS-RP (25% vs 15%, p = 0.204). At one month follow-up for PUS-RP and RS-RP, there was no significant difference in the frequency of continent men (69.2% vs. 76.9%, p = 0.302). At 3-month follow-up for the two groups of patients, again, there was no significant difference in the frequency of continence for PUS-RP and RS-RP (86.2% vs 88%, p = 0.824). Patients who underwent RS-RP had similar rates of continence to those patients undergoing PUS-RP in the short-term post-operative period.

Plant-based diet associated with better quality of life in prostate cancer survivors.

BACKGROUND: Plant-based diets have many health benefits, including a lower risk of fatal prostate cancer, and greater environmental sustainability. However, less is known regarding the impact of plant-based diets on quality of life among individuals diagnosed with prostate cancer. The authors' objective was to examine the relationship between plant-based diet indices postdiagnosis with quality of life. METHODS: This prospective cohort study included 3505 participants in the Health Professionals Follow-Up Study (1986-2016) with nonmetastatic prostate cancer. Food-frequency questionnaires were used to calculate overall and healthful plant-based diet indices. Quality-of-life scores were calculated using the Expanded Prostate Cancer Index Composite. Generalized estimating equations were used to examine associations over time between plant-based diet indices and quality-of-life domains (sexual functioning, urinary irritation/obstruction, urinary incontinence, bowel functioning, hormonal/vitality), adjusted for demographics, oncologic history, body mass index, caloric intake, health-related behaviors, and comorbidities. RESULTS: The median age at prostate cancer diagnosis was 68 years; 48% of patients underwent radical prostatectomy, and 35% received radiation as primary therapy. The median time from diagnosis/treatment to first the quality-of-life questionnaire was 7.0 years. A higher plant-based diet index was associated with better scores for sexual function, urinary irritation/obstruction, urinary incontinence, and hormonal/vitality. Consuming more healthful plant-based foods was also associated with better sexual and bowel function, as well as urinary incontinence and hormonal/vitality scores in the age-adjusted analysis, but not in the multivariable analysis. CONCLUSIONS: This prospective study provides supportive evidence that greater consumption of healthful plant-based foods is associated with modestly higher scores in quality-of-life domains among patients with prostate cancer.

Is there any difference in urinary continence between bilateral and unilateral nerve sparing during radical prostatectomy? A systematic review and meta-analysis.

CONTEXT: In men with prostate cancer, urinary incontinence is one of the most common long-term side effects of radical prostatectomy (RP). The recovery of urinary continence in patients is positively influenced by preserving the integrity of the neurovascular bundles (NVBs). However, it is still unclear if bilateral nerve sparing (BNS) is superior to unilateral nerve sparing (UNS) in terms of post-RP urinary continence. The aim of this study is to systematically compare the differences in post-RP urinary continence outcomes between BNS and UNS. METHODS: The electronic databases of PubMed and Web of Science were comprehensively searched. The search period was up to May 31, 2023. English language articles comparing urinary continence outcomes of patients undergoing BNS and UNS radical prostatectomy were included. Meta-analyses were performed to calculate pooled relative risk (RR) estimates with 95% confidence intervals for urinary continence in BNS and UNS groups at selected follow-up intervals using a random-effects model. Sensitivity analyses were performed in prospective studies and robotic-assisted RP studies. RESULTS: A meta-analysis was conducted using data from 26,961 participants in fifty-seven studies. A meta-analysis demonstrated that BNS improved the urinary continence rate compared to UNS at all selected follow-up points. RRs were 1.36 (1.14-1.63; p = 0.0007) at ≤ 1.5 months (mo), 1.28 (1.08-1.51; p = 0.005) at 3-4 mo, 1.12 (1.03-1.22; p = 0.01) at 6 mo, 1.08 (1.05-1.12; p < 0.00001) at 12 mo, and 1.07 (1.00-1.13; p = 0.03) at ≥ 24 mo, respectively. With the extension of the follow-up time, RRs decreased from 1.36 to 1.07, showing a gradual downward trend. Pooled estimates were largely heterogeneous. Similar findings were obtained through sensitivity analyses of prospective studies and robotic-assisted RP studies. CONCLUSION: The findings of this meta-analysis demonstrate that BNS yields superior outcomes in terms of urinary continence compared to UNS, with these advantages being sustained for a minimum duration of 24 months. It may be due to the real effect of saving the nerves involved. Future high-quality studies are needed to confirm these findings.

Simple versus Radical Hysterectomy in Women with Low-Risk Cervical Cancer.

BACKGROUND: Retrospective data suggest that the incidence of parametrial infiltration is low in patients with early-stage low-risk cervical cancer, which raises questions regarding the need for radical hysterectomy in these patients. However, data from large, randomized trials comparing outcomes of radical and simple hysterectomy are lacking. METHODS: We conducted a multicenter, randomized, noninferiority trial comparing radical hysterectomy with simple hysterectomy including lymph-node assessment in patients with low-risk cervical cancer (lesions of ≤2 cm with limited stromal invasion). The primary outcome was cancer recurrence in the pelvic area (pelvic recurrence) at 3 years. The prespecified noninferiority margin for the between-group difference in pelvic recurrence at 3 years was 4 percentage points. RESULTS: Among 700 patients who underwent randomization (350 in each group), the majority had tumors that were stage IB1 according to the 2009 International Federation of Gynecology and Obstetrics (FIGO) criteria (91.7%), that had squamous-cell histologic features (61.7%), and that were grade 1 or 2 (59.3%). With a median follow-up time of 4.5 years, the incidence of pelvic recurrence at 3 years was 2.17% in the radical hysterectomy group and 2.52% in the simple hysterectomy group (an absolute difference of 0.35 percentage points; 90% confidence interval, -1.62 to 2.32). Results were similar in a per-protocol analysis. The incidence of urinary incontinence was lower in the simple hysterectomy group than in the radical hysterectomy group within 4 weeks after surgery (2.4% vs. 5.5%; P = 0.048) and beyond 4 weeks (4.7% vs. 11.0%; P = 0.003). The incidence of urinary retention in the simple hysterectomy group was also lower than that in the radical hysterectomy group within 4 weeks after surgery (0.6% vs. 11.0%; P<0.001) and beyond 4 weeks (0.6% vs. 9.9%; P<0.001). CONCLUSIONS: In patients with low-risk cervical cancer, simple hysterectomy was not inferior to radical hysterectomy with respect to the 3-year incidence of pelvic recurrence and was associated with a lower risk of urinary incontinence or retention.

Long-term outcomes of pelvic-fascia sparing robotic-assisted radical prostatectomy versus standard technique: Superior urinary function and quality of life without compromising oncologic efficacy in a single-surgeon series.

BACKGROUND: Prostatic fascia-sparing robotic-assisted radical prostatectomy (PFS-RARP) has improved short-term postoperative continence compared to standard prostatectomy (S-RARP) but long-term differences remain unclear. MATERIALS AND METHODS: One hundred two S-RARP followed by 239 PFS-RARPs were performed by a single surgeon. Univariate analyses were performed with t-test, χ2, Wilcoxon rank sum, Fisher exact, and analysis of variance (ANOVA). Regression models analyzed associates of EPIC-CP scores and oncologic outcomes. Cox proportional hazards modeling assessed postoperative continence. Primary outcomes included patient-reported urinary incontinence (UI) via EPIC-CP and continence rates. Secondary outcomes included EPIC-CP scores, positive surgical margins (PSM), and biochemical recurrence (BCR). Perioperative outcomes and time to continence were measured. RESULTS: Median follow-up for PFS-RARP vs. S-RARP was 26 vs. 65 months. PFS-RARP demonstrated improved EPIC-CP UI and total scores at 24 months. On multivariate analysis, PFS-RARP was associated with improved EPIC-CP UI and total scores through 18 months, but not with PSM or BCR. PFS-RARP had a 39% and 66% reduced risk of incontinence using 0 and 0 to 1 pad-use definitions (HR 0.61, 95% CI 0.39 - 0.95; HR:0.34, 95% CI 0.16 - 0.76). Continence returned faster with PFS-RARP (0 PPD: 91.0 days vs. 261 days, P < 0.001; 0-1 PPD: 32.7 days vs. 171 days, P < 0.001). There were no differences in PSM (35% vs. 25%, P = 0.064). There were more anterior PSM in PFS-RARP vs. S-RARP (47% vs. 26% P = 0.035), but no differences in BCR (16% vs. 22% P = 0.241). CONCLUSIONS: PFS-RARP improves continence and patient-reported QOL up to 24 months postoperatively without compromising oncologic outcomes.

Placement of an artificial urethral sphincter for treatment of passive urinary incontinence after inadvertent prostatectomy and balloon dilation treatment for stricture formation in a 5-month-old dog.

OBJECTIVE: Describe the management of incontinence with several therapies, culminating with the apparently successful treatment utilizing artificial sphincter placement following an inadvertent prostatectomy. ANIMAL: 5-month-old 7.5-kg male neutered Miniature Schnauzer. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The patient was referred for dysuria and persistent stranguria following an iatrogenic total prostatectomy and urethrectomy. An extra pelvic urethral anastomosis was performed, followed by hospitalization for 2 weeks with a urinary catheter. The patient was further investigated for persistent stranguria, and a contrast urethrogram revealed a urethral stricture at the anastomosis site, which was treated with fluoroscopic balloon dilation. The stranguria resolved, but an acute nocturnal grade 3 passive urinary incontinence occurred, which was nonresponsive to medical management of phenylpropanolamine hydrochloride and estriol. An artificial urethral sphincter was placed, leading to continence after 5 top-ups to a total volume of 0.9 mL. The patient remained continent for 5.5 weeks before abrupt incontinence recurred, which was resolved by another 0.1-mL top-up. No further signs of incontinence occurred in the 11 months following. TREATMENT AND OUTCOME: The placement of an artificial urethral sphincter successfully managed urinary incontinence in this patient. Continence was achieved with no significant complications other than a transient loss of continence. Long-term follow-up 14 months after sphincter placement revealed that the patient had remained continent since the final sphincter top-up. The owner reported a significant improvement in the patient's quality of life following successful incontinence management. CLINICAL RELEVANCE: This case highlighted the benefits of placing an artificial urethral sphincter in managing urinary incontinence after select cases of prostatectomy in dogs that are unresponsive to medical management.

Detrusor underactivity after radical prostatectomy: A prospective observational study.

OBJECTIVE: To evaluate the impact of radical prostatectomy (RP) on bladder function with special interest in detrusor underactivity (DU) and to appraise clinical significance of DU in postprostatectomy patients. MATERIAL AND METHODS: This was a prospective, observational study conducted on male patients subjected to laparoscopic RP (LPR). Urodynamic studies were performed at the day before surgery (visit 1), 3-6 months postoperatively (visit 2) and more than 12 months after surgery (visit 3). Incidence of DU that occurred after LPR (de novo DU), incidence of persisting de novo DU after 12 months, clinical relevance of DU after LPR and predictive factors of de novo DU were assessed. RESULTS: 99 of 100 patients underwent preoperative urodynamic study (visit 1) and those were included in further analysis. 84 and 76 patients were available for follow-up at second and third visit respectively. De novo DU occurred after LPR in 25 (29.7%) patients at visit 2 (p < 0.001). Sixteen from 24 patients (66,7%) who developed de novo DU after RP (visit 2) continued to have DU 1 year after surgery (visit 3) (p = 0.04). On the multivariate analysis, urinary incontinence requiring more than 1 pad per day (odds ratio [OR] 5.11; confidence interval [CI] 1.69-17.19; p = 0.005) and preoperative IPSS storage sub-score (OR 1.25; CI 1.03-1.63; p = 0.030) were significantly associated with de novo DU. Postprostatectomy patients with DU had significantly lower Urinary Assessment of the Expanded Prostate Cancer Index Composite (EPIC) total score (819 vs. 911, p = 0.02), EPIC Function domain score (300 vs. 357, p = 0.002) and EPIC Urinary incontinence domain (137 vs. 224, p = 0.002) when compared to their counterparts without DU. CONCLUSIONS: RP substantially influences bladder function, causing de novo DU, which persists in substantial number of patients 1 year postoperatively. Furthermore, significant correlation between DU and postprostatectomy urinary incontinence may play a role when anti-incontinence surgery is considered.

Outcomes of lateral approach in robot-assisted radical prostatectomy: insights from a single-surgeon experience.

In the era of robotic prostate surgery, various techniques have been developed to improve functional outcomes. Urinary continence has shown satisfactory results, but the preservation of lateral nerves to the periprostatic capsule is only achievable by sparing the pubovesical complex. This study aims to present the first cases of lateral-approach robot-assisted radical prostatectomy (LRRP) performed by a novice surgeon. We conducted a retrospective analysis of 70 prostate cancer patients who underwent LRRP between October 2019 and September 2021, analyzing the perioperative and functional outcomes. The median operative time and intraoperative blood loss were 102 (92-108) minutes and 150 (130-180) mL, respectively. Five minor postoperative complications were reported, and the median hospital stay was 2 (1-2) days. Eleven positive surgical margins occurred. Potency and urinary continence recovery were achieved in 59 (84%) and 66 (94%) patients, respectively, 12 months after surgery. Our analysis shows that LRRP is a safe and effective procedure for prostate cancer surgery. Continence and potency recovery required a short learning curve, with an acceptable recovery rate even in the initial cases.

External validation of predictive models of sexual, urinary, bowel and hormonal function after surgery in prostate cancer subjects.

BACKGROUND: In 2020, a research group published five linear longitudinal models, predict Expanded Prostate Cancer Index Composite-26 (EPIC-26) scores post-treatment for radical prostatectomy, external beam radiotherapy and active surveillance collectively in US patients with localized prostate cancer. METHODS: Our study externally validates the five prediction models for patient reported outcomes post-surgery for localised prostate cancer. The models' calibration, fit, variance explained and discrimination (concordance-indices) were assessed. Two Australian validation cohorts 1 and 2 years post-prostatectomy were constructed, consisting of 669 and 439 subjects, respectively (750 in total). Patient reported function in five domains post-prostatectomy: sexual, bowel, hormonal, urinary incontinence and other urinary dysfunction (irritation/obstruction). Domain function was assessed using the EPIC-26 questionnaire. RESULTS: 1 year post-surgery, R2 was highest for the sexual domain (35%, SD = 0.02), lower for the bowel (21%, SD = 0.03) and hormone (15%, SD = 0.03) domains, and close to zero for urinary incontinence (1%, SD = 0.01) and irritation/obstruction (- 5%, SD = 0.04). Calibration slopes for these five models were 1.04 (SD = 0.04), 0.84 (SD = 0.06), 0.85 (SD = 0.06), 1.16 (SD = 0.13) and 0.45 (SD = 0.04), respectively. Calibration-in-the-large values were - 2.2 (SD = 0.6), 2.1 (SD = 0.01), 5.1 (SD = 0.1), 9.6 (SD = 0.9) and 4.0 (SD = 0.2), respectively. Concordance-indices were 0.73, 0.70, 0.70, 0.58 and 0.62, respectively (all had SD = 0.01). Mean absolute error and root mean square error were similar across the validation and development cohorts. The validation measures were largely similar at 2 years post-surgery. CONCLUSIONS: The sexual, bowel and hormone domain models validated well and show promise for accurately predicting patient reported outcomes in a non-US surgical population. The urinary domain models validated poorly and may require recalibration or revision.

Incidence of urinary incontinence after hip fracture surgery and associated risk factors: a prospective study.

BACKGROUND: The contribution of the postoperative process to developing or worsening urinary incontinence (UI) after hip fracture surgery (HFS) remains unclear. We aimed to evaluate UI incidence and worsening among older patients undergoing HFS, and explore associated risk factors. METHODS: This prospective cohort study included patients ≥ 75 years admitted between October 2019 and October 2021 to the Traumatology Service of three hospitals in the Consorci Sanitari de Alt-Penedès i Garraf (Barcelona, Spain) with hip fracture requiring surgical treatment. UI was assessed using the first two questions of the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) at baseline and at days 30 (± 3 days) and 90 (± 3 days) after HFS. Surgery-related data and post-surgical complications were recorded. RESULTS: A total of 248 patients with a mean (SD) age of 85.8 (6.78) years were included; 77.8% were female and 154 (62.1%) had UI at baseline. After HFS, 3.24% experienced urinary tract infections (UTIs), 3.64%, acute urinary retention (AUR), 8.57%, constipation, and 53.9%, prolonged catheterization (> 24 h). Fifty-eight patients without baseline UI developed UI at 30 days, resulting in a UI incidence of 61.7% (95% CI 51.1-71.54) between days 0 and 30. Of the 248 patients, 146 (59.1%) experienced worsening of UI. AUR and UTIs were identified as risk factors for UI development and worsening after HFS, respectively. CONCLUSION: The incidence of UI in older patients after HFS is significant. Patient management protocols should consider AUR and UTIs to reduce or eliminate the incidence of UI in older patients undergoing HFS.
