To evaluate the performance of a mathematical model to drive preoperative planning between RIRS and MiniPerc (MP) for the treatment of renal stones between 10 and 20 mm. Patients with a renal stone between 10 and 20 mm were enrolled. A mathematical model named Stone Management According to Size-Hardness (SMASH) score was calculated: hounsfield units (HU) χ stone maximum size (cm)/100. Patients were divided into 4 groups: RIRS with score < 15 (Group A), RIRS with score ≥ 15 (Group B), MP with score < 15 (Group C), MP with score ≥ 15 (Group D). Cyber Ho device was always used. Stone free rate (SFR) was assessed after 3 months. Complication rate and need for auxiliary procedures were evaluated. Between January 2019 and December 2021, 350 patients were enrolled (87, 88, 82 and 93 in Groups A, B, C and D). Mean stone size was 13.1 vs 13.3 mm in Group A vs B (p = 0.18) and 16.2 vs 18.1 mm in Group C vs D (p = 0.12). SFR was 82%, 61%, 75% and 85% for Groups A, B, C and D. SFR was comparable between Groups C and D (p = 0.32) and Groups A and C (p = 0.22). SFR was significantly higher in Group A over B (p = 0.03) and in Group D over B (p = 0.02). Complication rate was 2.2%, 3.4%, 12.1%, 12.9% for Groups A, B, C, D. RIRS and MP are both safe and effective. The mathematical model with the proposed cut-off allowed a proper allocation of patients between endoscopic and percutaneous approaches.Registration number of the study ISRCTN55546280.

OBJECTIVE: To compare intra and early postoperative outcomes between pulsed-wave and continuous-wave Thulium Fiber Laser Enucleation of the Prostate (PW-ThuFLEP vs CW-ThuFLEP) for the treatment of benign prostatic hyperplasia. METHODS: 238 patients with lower urinary tract symptoms due to benign prostatic hyperplasia underwent PW-ThuFLEP (118 patients) vs CW-ThuFLEP (120 patients). Preoperative prostate volume, adenoma volume, prostate-specific antigen (PSA), and hemoglobin values were recorded. International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual volume, and International Index of Erectile Function-5 score (IIEF-5) were assessed. Operative time, enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin drop, and postoperative complications were recorded. Micturition improvements and sexual outcomes were evaluated 3months after surgery. RESULTS: CW-ThuFLEP showed shorter operative time (61.5 vs 67.4 minutes, P = .04). Enucleation time (50.2 vs 53.3 minutes, P = .12), enucleation efficiency (0.8 vs 0.7 g/min, P = .38), catheterization time (2.2 vs 2.1days, P = .29), irrigation volume (32.9 vs 32.8L, P = .71), hospital stay (2.8 vs 2.6days, P = .29) and hemoglobin drop (0.38 vs 0.39 g/dL, P = .53) were comparable. No significant difference in complication rate was observed. At 3-month follow-up, the procedures did not show any significant difference in IPSS, Qmax, post-void residual volume, IIEF-5, and PSA value. CONCLUSION: PW-ThuFLEP and CW-ThuFLEP both relieve lower urinary tract symptoms equally, with high efficacy and safety. Operative time was significantly shorter with CW-ThuFLEP, but with a small difference with low clinical impact. Enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin and PSA drop, complication rate, and sexual outcomes showed no differences.

OBJECTIVES: To assess the accuracy of targeted and systematic biopsies for the detection of prostate cancer (PCa) and clinically significant PCa (csPCa) in the everyday practice, evaluating the need for additional systematic biopsies at the time of targeted biopsy. PATIENTS AND METHODS: From our multicentric database gathering data on 2,115 patients who underwent fusion biopsy with Koelis™ system between 2010 and 2017, we selected 1,119 patients who received targeted biopsies (a median of 3 for each target), followed by systematic sampling of the prostate (12 to 14 cores). Overall and clinically significant cancer detection rate (CDR) of Koelis™ fusion biopsies were assessed, comparing target and systematic biopsies. Secondary endpoint was the identification of predictors of PCa detection. RESULTS: The CDR of targeted biopsies only was 48% for all cancers and 33% for csPCa. The performance of additional, systematic prostate sampling improved the CDR of 15% for all cancers and of 12% for csPCa. PCa was detected in 35%, 69%, and 92% of patients with lesions scored as PI-RADS 3, 4 and 5, respectively. Elevated PI-RADS score and positive digital rectal examination were predictors of PCa, whereas biopsy-naïve status was associated with csPCa. CONCLUSION: In the everyday practice target biopsy with Koelis™ achieves a good CDR for all PCa and csPCa, which is significantly improved by subsequent systematic sampling of the prostate. The outstanding outcomes of fusion biopsy are confirmed also in biopsy-naïve patients. Elevated PI-RADS score and positive digital rectal examination are strongly associated with presence of PCa.

OBJECTIVE: To evaluate the accuracy in histologic grading of MRI/US image fusion biopsy by comparing histopathology between systematic biopsies (SB), targeted biopsies (TB) and the combination of both (SB + TB) with the final histopathologic outcomes of radical prostatectomy specimens. MATERIALS AND METHODS: Retrospective, multicentric study of 443 patients who underwent SB and TB using MRI/US fusion technique (Urostation® and Trinity®) prior to radical prostatectomy between 2010 and 2017. Cochran's Q test and McNemar test were conducted as a post hoc test. Uni-multivariable analyses were performed on several clinic-pathological variables to analyze factors predicting histopathological concordance for targeted biopsies. RESULTS: Concordance in ISUP (International Society of Urological Pathology) grade between SB, TB and SB + TB with final histopathology was 49.4%, 51.2%, and 63.2% for overall prostate cancer and 41.2%, 48.3%, and 56.7% for significant prostate cancer (ISUP grade ≥ 2), respectively. Significant difference in terms of concordance, downgrading and upgrading was found between SB and TB (ISUP grade ≥ 2 only), SB and SB + TB, TB and SB + TB (overall ISUP grade and ISUP grade ≥ 2) (p < 0.001). Total number of cores and previous biopsies were significant independent predictive factors for concordance with TB technique. CONCLUSION: In this retrospective study, combination of SB and TB significantly increased concordance with final histopathology despite a limited additional number of cores needed.

OBJECTIVES: To evaluate the feasibility and morbidity and mortality of laparoscopic radical cystectomy for bladder cancer in elderly patients. METHODS: Prospective study conducted between January 2003 and May 2009 in 22 patients, one woman and 21 men, who underwent laparoscopic radical cystectomy for bladder cancer. Mean patient age was 76.2+/-4.3 years. The median preoperative ASA score was 2 (1-3). The indication for surgery was an invasive muscle bladder tumour in 18 cases and noninvasive muscle bladder cancer refractory to conservative treatment (chemotherapy, immunotherapy) in four cases. Ileal conduit was carried out in 15 cases. An ileal neobladder was fashioned in six cases using Camey's technique. One bilateral cutaneous ureterostomy was performed. RESULTS: There was one conversion to open surgery. One intraoperative complication was noted (left obturator nerve injury). Mean blood loss was 377.5+/-341.2ml. No perioperative death was observed. Mean time to resumption of oral fluids was 2.4+/-1.6 days and mean time to resumption of solids was 4.5+/-1.6 days. Mean time to resumption of bowel movements was 3.9+/-1.9 days. Mean critical care unit was 4.2+/-1.4 days. Five patients (22.7 %) had postoperative complications. Postoperative narcotic analgesics were necessary in 60 % of cases. Mean hospital stay was 11.0+/-3.0 days. Mean patient follow-up was 46.4+/-20.8 months. CONCLUSIONS: Laparoscopic radical cystectomy for bladder cancer in elderly patients is associated with low morbidity, and a limited hospital stay.

OBJECTIVE: To determine the survival and prognosis criteria of pT3NxM0 prostate tumours (TNM 2002) after radical retropubic prostatectomy (RRP). MATERIAL AND METHODS: Between 1988 and 2000, 606 consecutive RRP were performed for T1-3 tumours, whose 246 (40.6%) specimens were classified pT3, followed in 53 cases by adjuvant radiotherapy and in 71 cases by salvage radiotherapy. Fifty-five patients received postoperative hormonotherapy at the time of biochemical recurrence. Biochemical recurrence was determined by two PSA values greater than 0.2 ng/ml. RESULTS: Mean age of this group was 65 years at surgery. Mean follow-up was 91.4 months. Mean preoperative PSA was 12.8 ng/ml. Distribution of cases was 170 pT3a (69.1%) and 76 (30,9%). At 10 years, the biochemical progression-free, metastasis-free, specific and overall survival was 54, 86, 92 and 75% respectively. Worse biochemical prognostic factors were lymph node extension, high Gleason score, high preoperative PSA, seminal vesicles involvement, positive surgical margins and adjuvant radiotherapy absence. CONCLUSION: This study shows that pT3 tumours treated with therapeutic associations including RRP presents an excellent specific survival at 10 years. The determination of biochemical recurrence prognostic factors could help to select patients who need complementary treatments after surgery.

Urachus pathologies are very rare but require to be known by urologists. Lack of appropriate treatment exposes the patients to the risks of symptoms recurrence, infectious complications or adenocarcinomatous degeneration. A partial or total defect of obliteration of the urachus channel after the fifth month of gestation can be at the origin of four benign pathologies. The ombilicovesical fistula (47.6%) is diagnosed at the native period. In the adult, the most frequent form is the cyst (30.7%) whereas the external (16.4%) and internal sinus (3.2%) are rarer. Diagnosis depends on the clinical examination and the association of sonography and TDM. The risk of complications must systematically result in proposing a surgical treatment for these benign pathologies. The umbilicus resection is not recommended, but the surgeon has to remove the urachus and its implantation base on the bladder. Laparoscopic surgery seems to be an interesting route for this intervention.
