Objective: To evaluate the long-term functional and oncologic outcomes after robotic partial nephrectomy (RAPN) and radical nephrectomy (RARN). Materials and Methods: A retrospective review was performed on 1816 patients who underwent RAPN and RARN at our institution between January 2006 and January 2018. Patients with long-term follow-ups of at least 5 years were selected. Exclusion criteria included patients with a previous history of partial or radical nephrectomy, known genetic mutations, and whose procedures were performed for benign indications. Statistical analysis was performed with results as presented. Results: A total of 769 and 142 patients who underwent RAPN and RARN, respectively, met our inclusion criteria. The duration of follow-up was similar after the two procedures with a median of ∼100 months. The 5- and 10-year chronic kidney disease (CKD) upstaging-free survivals were 74.5% and 65.9% after RAPN and 53% and 46.4% after RARN, respectively. Older age was identified as a potential predictor for CKD progression after RARN, whereas older age, higher body mass index, baseline renal function, and ischemia time were shown to predict CKD progression after RAPN. Renal cell carcinoma–related mortality rates for RAPN and RARN were equally 1.1%. No statistically significant differences were identified in the local recurrence, metastatic, and disease-specific survival between the two procedures. Conclusion: Compared with RARN, RAPN conferred a better CKD progression-free survival. Several factors were identified as potential predictors for clinically significant CKD progression both in the early and late postoperative phase. Long-term oncologic outcomes between the two procedures remained similarly favorable. [ABSTRACT FROM AUTHOR]

Introduction: Prostate cancer diagnosis and treatment is challenging in surgically complex patients. Radical prostatectomy can be performed without peritoneal entry using novel single-port (SP) transperineal (TP) and transvesical (TV) approaches. We sought to examine the outcomes of radical prostatectomy using novel TP and TV approaches in patients with extensive prior abdominal surgeries. Materials and Methods: From 2019 to 2023, 51 patients with extensive prior abdominal surgeries were identified who underwent TP (18) and SP TV (33) robotic radical prostatectomy. Indications included history of various surgeries with open laparotomy, including J-pouch reconstruction (22, 43%), active stoma (14, 27%), and open bowel resection (9, 18%). In all patients, 12/51 (24%) had a history of incisional hernia repair with mesh. A retrospective analysis was performed. Results: All cases were completed without open conversion, bowel injuries, or blood transfusions. Length of stay was 5.6 hours for TV and 22 hours for TP. No opioids were prescribed in 91% of TV vs 56% of TP. One intraoperative complication (ureteral injury) occurred in a patient undergoing the TP approach. Postoperative complications were noted in 14/51 (27%), including 10/18 (56%) TP vs 4/33 (12%) TV. High-grade complications (Clavien 3) occurred in three patients (6%, all TP). Pathologic staging showed pT3 in 26/51 (17 TV vs 9 TP), while the remainder were pT2. Biochemical recurrences were noted in four patients (8%, three TV and one TP). Immediate continence was noted in 30% of TV patients. Long-term continence after 12 months was 92% in TV and 67% in TP. Conclusions: In patients with extensive prior abdominal surgeries, radical prostatectomy is feasible using a TP or TV approach. No bowel injuries or open conversion were observed. The SP TV approach offers advantages of shorter hospital stay, shorter catheter duration, less opioid use, fewer complications, and improved continence recovery. [ABSTRACT FROM AUTHOR]
