Introduction. According to several studies, an increased body mass index (BMI) may be one of the unfavorable prognostic factors of prostate cancer (PC) associated with lower oncological and functional outcomes of radical prostatectomy (RP).Purpose of the study. To evaluate pathomorphological characteristics, recurrence-free survival, and restoration of erectile function (EF) after RP with nerve-sparing technique (NST) in obese patients.Materials and methods. The study group consisted of 91 patients with BMI ≥ 30 kg/m2 , the control group consisted of 356 patients with BMI < 30 kg/m2 who underwent RP with unilateral or bilateral NST from January 2012 to December 2019. A comparative analysis of pathomorphological results, the rate of complications, recurrence-free survival, and the dynamics of EF restoration in both groups was performed.Results. Obese patients had a larger prostate volume, a higher score for the International Prostate Symptom Score (IPSS) questionnaire. Unilateral and bilateral NST was used in both groups in equal proportions: 50.5% and 49.5% in the group with BMI ≥ 30 and 51.4% and 48.6% in the group with BMI < 30 (p = 0.88 ) There were no significant differences between the groups in the rate of adverse pathomorphological characteristics, serious postoperative complications and the volume of intraoperative blood loss. The five-year recurrence-free survival after RP was 93.1% in the BMI group ≥ 30 and 95.1% in the BMI group < 30 (p = 0.55). The total rate of EF recovery after RP with NST after 24 months was 75% and 78.5% (p = 0.24). The restoration of EF in obese patients was slower: sufficient for sexual intercourse EF after 6 and 12 months was observed in 17.9% and 32.1% versus 35.4% and 53.8% in the group with BMI < 30, and the meantime to recovery was 10.9 (± 1) and 8.6 (± 0.6) months, respectively (p = 0.04).Conclusions. Obesity does not affect the pathomorphological and oncological results of RP with NST. EF recovery in patients with a BMI of ≥ 30 is slowed down, however, 24 months after surgery, the results are comparable with the potency level in patients with a BMI < 30. The data obtained may be of value in counselling and planning surgical intervention in obese patients with PC.

Objective: To present a retrospective analysis on the oncological and functional outcomes of a single-center experience on a large series of extraperitoneal laparoscopic radical prostatectomies (eLRP) with an extended follow-up. Materials and methods: Herein we present a retrospective review of patients who underwent eLRP. Oncological and functional follow-up data were collected by means of outpatient visits and telephone interviews, assessing overall mortality and biochemical recurrence-free survival. Patients with clinical T4 stage prostate cancer (PCa), previous surgery for benign prostatic hyperplasia (BPH), previous androgen deprivation, radiotherapy, concomitant chemotherapy and/or experimental therapies, and with insufficient follow-up data were excluded. Preoperative data recorded were age, body mass index, ultrasound prostate volume, preoperative PSA and clinical stage of PCa. Operative data (operative time, nerve sparing technique and any perioperative complication) and pathological findings were obtained by consulting the surgical and pathological reports. Oncological and functional follow-up were collected during follow-up visits and telephone interview. Results: Between January 2001 and December 2019, overall 938 eLRP were performed at our Institution. The median follow-up was 132 months. 69.7% of the patients had complete dataset. The estimated overall biochemical recurrence (BCR)-free survival was 71.4% at 5 years and 58.9% at 10 years. Cancer specific survival was 84,5%. Erectile function was preserved in the most of patients as postoperative IIEF-5 score within 12 months after surgery was > 12 in the 82.1%. About the urinary incontinence, 0.76% of the patients presented severe incontinence (continued and persistent loss of urine) and 7.0% were mildly incontinent (using up to one pad per day). Conclusions; eLRP has shown oncological and functional results comparable to other minimally invasive techniques and to open radical prostatectomy (ORP), with favorable perioperative outcomes than the open technique and a reduced complication rate.

<b><i>Introduction:</i></b> A history of transurethral surgery of the prostate is generally considered as a risk factor of adverse functional outcomes after radical prostatectomy (RP). We tested whether the risk of postoperative urinary incontinence (UIC) and erectile dysfunction (ED) after RP could be further substantiated in such patients. <b><i>Materials and Methods:</i></b> We tested the effect of the following variables on UIC and ED rates 1 year after RP: residual prostate volume after transurethral desobstruction, the time from transurethral desobstruction to RP, the type of transurethral desobstruction (TURP vs. laser enucleation), age, and nerve-sparing surgery (yes vs. no). UIC was defined as usage of any pad except a safety pad. ED was defined as no sexual intercourse possible. <b><i>Results:</i></b> Overall, 216 patients treated with RP between 2010 and 2019 in a tertiary care center were evaluated. All patients had previously undergone transurethral desobstruction. Regarding UIC analyses, only time from transurethral desobstruction to RP significantly influenced UIC rates (<i>p</i> = 0.003). Regarding ED rates, none of the tested variables reached statistical significance. <b><i>Conclusion:</i></b> The risk of UIC and ED after RP is substantial in men who had previously undergone transurethral desobstruction. The time from transurethral desobstruction to RP significantly impacts on the postoperative UIC rates. This observation should be further explored in future studies.

Partial nephrectomy has become a treatment of choice for clinical T1a renal masses. Some international guidelines suggest that partial nephrectomy can be applied also in clinical T1b tumors. The aim of this study was to evaluate the feasibility of partial nephrectomy for tumors larger than 4 cm. We reviewed the medical records of 1280 patients who underwent partial nephrectomy and had pathologically confirmed malignancy. Patients were categorized into two groups by the size of tumors on computed tomography image, with a cutoff value of 4 cm. The oncologic and functional outcomes were compared between the two groups. Recurrence-free survival after surgery was estimated using the Kaplan-Meier method. Of the 1280 patients, 203 patients (15.9%) had renal tumors larger than 4 cm. There were significantly more exophytic tumors (P &lt; 0.001) and the R.E.N.A.L. scores were significantly higher (P &lt; 0.001) in partial nephrectomy &gt;4 cm. Mean ischemic times were significantly different (P &lt; 0.001). After 24 months, mean creatinine level between partial nephrectomy &gt;4 cm and partial nephrectomy ≤4 cm was not different significantly (P = 0.554). And the percent changes of glomerular filtration rate after partial nephrectomy were not different at last follow-up (P = 0.082). The 5-year recurrence-free survival rates were 96.6% in partial nephrectomy ≤4 cm, and 94.5% in partial nephrectomy &gt;4 cm (P = 0.416). Based on the present findings, partial nephrectomy for tumors larger than 4 cm showed comparable feasibility and safety to partial nephrectomy for tumors ≤4 cm considering oncologic and functional outcomes, despite longer operative and ischemic time.

Objective: To appraise the outcomes on the Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) learning curve of a surgeon with previous experience of anterior (standard) RARP. Materials and methods: The first 50 cases during the Rs-RARP learning curve (group 1) and 50 cases after the second 100 cases with the standard approach (group 2) were comprised in the study. Patients who used zero or one safety pads were considered continent. Erectile function recuperation was characterized as the competence to achieve penetrative intercourse without receiving any medication. All patients were reevaluated at two weeks, first, third, sixth, and 12th months after surgery using IIEF-5, PSA level, and continence status. Results: Immediate continence rates following catheter removal were 32/50 (64%) in Rs-RARP group and 26/50 (52%) in S-RARP group (p = 0.224). The continence recovery rate was 48/50 (96%) in Rs-RARP group and 46/50 (92%) in the S-RARP group at 12 months follow-up (p = 0.400). Total nerve-sparing surgery was enforced in 36/50 (72%) patients for group 1 and 35/50 (70%) patients for group 2. Potency recovery was 27/43 (62.8%) in Rs-RARP and 30/44 (68.2%) for S-RARP at 12 months follow up (p = 0.597). Surgical margin positivity was detected in 6/50 (12%) cases in the Rs-RARP group and in 4/50 (8%) cases in the S-RARP (p = 0.444). Conclusions: Functional and oncological results are not negatively affected in the first 50 cases for a surgeon who is experienced in S-RARP before transition to the Rs-RARP method.
