Background/Objectives: Robot-assisted radical cystectomy (RARC) has become the primary approach for treating bladder cancer, replacing the traditional open procedure. The robotic approach, when combined with ureterocutaneostomy (UCS), offers significant advantages for octogenarians, who are at increased risk for perioperative complications. Methods: This observational, prospective, multicenter analysis is based on data from the Italian Radical Cystectomy Registry (RIC), collected from January 2017 to June 2020 across 28 major urological centers in Italy. We analyzed consecutive male and female patients undergoing radical cystectomy (RC) and urinary diversion via the open, laparoscopic, or robot-assisted technique. Inclusion criteria: patients aged 80 years or older, with a WHO Performance Status (PS) of 2–3, an American Society of Anesthesiologist score ≥3, a Charlson Comorbidity Index (CCI) ≥ 4, and a glomerular filtration rate (GFR) <60 mL/min. Results: A total of 128 consecutive patients were included: 41 underwent RARC with UCS (Group 1), 65 open RC (ORC) with UCS (Group 2), and 22 laparoscopic RC (LRC) with UCS (Group 3). The cystectomy operative time was longer in robotic surgeries, while the lymph node dissection time was shorter. RARC with UCS showed statistically significant advantages in terms of lower median estimated blood loss (EBL), transfusion rate, and length of hospital stay (LOS) compared to open and laparoscopic procedures. Intra- and postoperative complications were also lower in the RARC groups. Conclusions: Robotic cystectomy in high-volume referral centers (≥20 cystectomies per year) provides the best outcome for fragile patients. Beyond addressing the baseline pathology, RARC with UCS may represent a leading option, offering oncological control while reducing complications in this vulnerable age group.

Background: Non-muscle-invasive bladder cancer (NMIBC) represents approximately 70–75% of newly diagnosed bladder cancers and is characterized by high recurrence rates despite guideline-based management. Chronic urinary retention and bladder outlet obstruction (BOO) have been proposed as under-recognized modifiers of NMIBC outcomes through prolonged exposure to urinary carcinogens, inflammation, and altered intravesical pharmacokinetics. This narrative review qualitatively synthesizes biological and clinical evidence linking BOO-related dysfunction with NMIBC behavior and explores the emerging, but preliminary, role of Holmium Laser Enucleation of the Prostate (HoLEP) as a functional adjunct in selected patients. Methods: A narrative review was conducted according to SANRA guidelines. PubMed/MEDLINE, Embase, and Scopus were searched (January 2000–October 2025) using predefined terms for NMIBC, BOO, urinary retention, and HoLEP. Two reviewers independently screened records, with disagreements resolved by consensus. Sixty-one studies met inclusion criteria. Results: Elevated postvoid residual (PVR) (>80–100 mL) and moderate to severe lower urinary tract symptoms (LUTS) were consistently associated with higher NMIBC recurrence rates, independent of tumor stage and grade, in heterogeneous cohorts. Retention correlated with reduced efficacy of Bacillus Calmette–Guérin (BCG) and mitomycin C, likely via uneven drug distribution and a chronically inflamed urothelium. Mechanistic data support a plausible link between BOO-related inflammation, barrier dysfunction, and tumor biology, although direct biomarker correlations with PVR or pharmacokinetic studies are lacking. HoLEP provides durable relief of BOO, reduces PVR, and improves LUTS. Limited retrospective data suggest an association between HoLEP and lower recurrence, but these observations are confounded and should be viewed as hypothesis-generating. Conclusions: Chronic urinary retention and BOO appear to be modifiable functional factors that may influence NMIBC recurrence and intravesical therapy performance. HoLEP is a promising option to optimize bladder emptying in carefully selected patients, but its oncologic impact remains unproven and should be considered hypothesis-generating pending prospective, risk-adjusted studies.

Background/Objectives: Surgical refinements in robot-assisted partial nephrectomy (RAPN) aim to reduce morbidity and optimize renal function preservation, particularly in patients with high-complexity renal tumours. This study describes the no-touch adaptive technique for RAPN and compares its perioperative outcomes, postoperative complications, and resulting early renal function with those of the conventional approach. Methods: A cohort of 72 consecutive patients with high-complexity renal tumours undergoing RAPN was evaluated. The study group included 38 patients treated with the no-touch adaptive technique, while 34 patients underwent the conventional approach. The no-touch adaptive technique consisted of sutureless, off-clamp, simple tumour enucleation with incremental haemostasis and the option to shift to arterial clamping, tumour enucleoresection, or renorrhaphy as needed. The conventional technique involved on-clamp minimal enucleoresection with double-layer renorrhaphy. Outcomes assessed included completion of a fully no-touch procedure, perioperative metrics, 90-day postoperative complications, and 3-month renal function change from baseline. Results: Baseline characteristics were comparable between groups. A fully no-touch RAPN was achieved in 30/38 (79%) patients. Adaptations were required in eight cases: shift to main arterial clamping (n = 2), renorrhaphy (n = 5), or both (n = 1), with one conversion to total nephrectomy due to intractable bleeding. Estimated blood loss was similar between groups (study: 150 mL [IQR 75–250] vs. control: 180 mL [IQR 100–400]). Length of stay was significantly shorter in the study group (3 days [IQR 3–4]) compared with controls (5 days [IQR 6–8]). Any-grade 90-day complications were significantly lower with the no-touch technique (21% vs. 56%, p < 0.01). Clinically significant 3-month eGFR decline occurred in 14% of controls versus 0% of study patients (p = 0.02). Conclusions: The no-touch adaptive RAPN technique is feasible in high-complexity renal tumours and provides reduced morbidity and superior early renal function preservation compared with the conventional approach.

Introduction and Objectives: Local recurrence (LR) in patients treated with surgery for renal cell carcinoma (RCC) remains a significant clinical challenge that requires thorough investigation. Our study aimed to identify the relative risk factors and explore the optimal clinical management of LR. Materials and Methods: We conducted a non-randomized, observational, retrospective multicentric registry involving multiple Italian urological centers. We included patients treated with surgery (either nephron-sparing or radical nephrectomy) who later developed LR, defined as recurrence in the ipsilateral kidney or renal fossa. Patients with hereditary syndromes or metastatic disease at the time of LR diagnosis were excluded. Results: We reported 135 cases of LR with the following characteristics: most primary lesions were monofocal (85.7%), with a median size of 42 mm (23–53), the median R.E.N.A.L. score was 7 (6–8), and the median Padua score was 7 (6–9). Patients were treated with robot-assisted techniques in 59% of cases, laparoscopic surgery in 32.4%, and open surgery in 8.6%. Nephron-sparing surgery was performed in 75.2% of cases. Ischemia occurred in 61% of the cases, with a median ischemia time of 21 min (15.5–24). Intraoperative complications occurred in 3.8% of cases, while postoperative complications were reported in 13.8%, all of which were grade ≤3 according to the Clavien–Dindo classification. The primary tumors were pT1a in 43.5% of cases, pT1b in 26.3%, pT2 in 14.7% and pT3 in 15.5%. Histologically, 84% of cases were clear cell, 11.3% papillary type 1 or 2, and 3.7% chromophobe. Sarcomatoid/rhabdoid variants were present in 10.5% of cases. The median rate of LR was 1.3% (range 0.2–3.6), while the median time to LR was 18 months (12–39). LR occurred in the ipsilateral kidney in 70.5% of cases and in the ipsilateral renal fossa in 29.5%. The median rate of PSM in LR cases at initial surgery was 2.4% (range 0–4.3), while the median rate of negative surgical margin (NSM) in LR cases at initial surgery was 0.1 (0–0.3). Following LR diagnosis, most patients (49.2%) underwent surgery, 29.1% received cryoablation or radiotherapy, 17.1% received systemic treatment alone, and 4.6% followed a watchful waiting/active surveillance approach. At a median follow-up of 62 months, the highest oncological control in terms of 5-year cancer-specific survival and overall survival rates was achieved in surgically treated patients. The PSM, the histological variant, and their combination were found to be independent variables correlated with the occurrence of LR, with relative risks of 3.62, 2.71, and 8.12, respectively. Conclusions: LR after nephron-sparing or radical nephrectomy represents a significant clinical dilemma. Known risk factors are not always sufficient to predict recurrence, emphasizing the necessity of consistent radiological follow-up per guideline recommendations. Early detection of recurrence and a multidisciplinary approach involving expert centers are crucial for optimizing patient outcomes.

Neoadjuvant chemotherapy (NAC) followed by radical cystectomy is standard for muscle-invasive bladder cancer (MIBC), yet complete pathological response (ypT0) occurs in only a minority of patients. Its clinical and temporal predictors remain poorly defined, limiting optimized patient selection and treatment timing. We retrospectively analyzed 35 consecutive patients with MIBC (≤cN1M0) who achieved ypT0 after NAC followed by robot-assisted radical cystectomy (RARC) and compared them with 70 consecutive patients with residual disease (≥ypT1) treated at the same institution. Descriptive analyses were performed, followed by multivariable multinomial logistic regression to identify independent clinical and treatment-timing predictors of ypT0. Early initiation of NAC within one month of diagnosis (p=0.004), completion of chemotherapy within two months (p=0.003), completion of all planned cycles (p=0.02), favorable clinical restaging prior to RARC (p<0.001), and surgery within an optimal post-chemotherapy recovery window (p=0.01) were significantly associated with ypT0. On multivariable analysis, independent predictors of ypT0 included age <70 years (OR=10.5), early treatment initiation (OR=51.1), timely completion of NAC (OR=25.5), completion of all cycles (OR=44.4), surgery within the optimal recovery interval (OR=19.1), total treatment-to-surgery interval <6 months (OR=35.6), and lower tumor stage at restaging (OR=9.34). This study identified independent clinical and temporal predictors of complete pathological response following NAC and RARC for MIBC. Modifiable timing-related factors-including early treatment initiation, chemotherapy completion, and optimized surgical scheduling-were key to achieving ypT0, supporting improved patient selection and coordinated perioperative care in future studies.
