Purpose
After Endoscopic Enucleation of the Prostate (EEP) for benign prostatic obstruction (BPO), men remain at risk for prostate cancer (PCa). Significant PSA changes occur after enucleation, which ...interfere with later screening for PCa. It remains unclear which patients need further diagnostic investigations for PCa after EEP. The goal of this study was to identify an independent predictor for PCa diagnosis after Holmium Laser Enucleation of the Prostate (HoLEP) in patients whose HoLEP resection specimen did not show PCa.
Methods
Data of 773 patients who underwent HoLEP for BPO between 2010 and 2018 in a referral center were analyzed. Exclusion criteria were PCa detection in the HoLEP specimen or absence of post-operative PSA values. Patients were divided in a PCa group and Control group depending on whether or not PCa was detected during follow-up after HoLEP. The predictive value for future diagnosis of PCa of different forms of PSA-change after HoLEP was analyzed by multivariate Cox regression and ROC analysis.
Results
Overall, 24 (4.2%) patients developed PCa after HoLEP. At 5 year follow-up, the PCa-free survival rate was 85%. First post-operative PSA was an independent predictor of PCa diagnosis after HoLEP (HR 1.106, 95% CI 1.074–1.139,
p
< 0.001, ROC AUC 0.903) with an optimal cut-off value of 1.73 ng/ml (sensitivity 83.3%, specificity 82.3%).
Conclusions
For patients who underwent HoLEP for BPO, post-operative PSA after HoLEP is an independent predictor for future PCa diagnosis. When PSA is > 1.73 ng/ml within the first year after HoLEP, rigorous follow-up and diagnostic investigations for PCa are indicated.
Robot-Assisted Simple Prostatectomy (RASP) has emerged as a promising alternative in the treatment of benign prostatic obstruction (BPO). However, there is currently a lack of comparative studies ...evaluating different robotic platforms for performing RASP. Therefore, we aimed to compare perioperative and functional outcomes of RASP performed using the HUGO™ RAS System versus the DaVinci® Xi System.
Forty consecutive cases of RASP performed between May 2021 and March 2023 with the HUGO™ RAS and the DaVinci® Xi at OLV Hospital (Aalst, Belgium) were included in this retrospective study. All surgeries were performed by three experienced surgeons using the same approach. Baseline characteristics, peri-operative and functional outcomes were collected and compared between the two groups.
The population was equally divided between the two groups with 20 patients in each group. There were no significant differences in preoperative patient characteristics between the two groups, except for the presence of bladder stones prior to the surgery (p = 0.03). No significant differences in total operative time and console time between the two groups were reported (p = 0.3). No cases required conversion to open surgery or additional port placement. During one case performed with the HUGO™ RAS, a malfunctioning monopolar curved shear had to be replaced. However, there was no statistically significant differences in terms of technical robotic problems between the groups (p = 0.3). There was no significant difference between the two groups in perioperative and functional outcomes (all p ≥ 0.2).
We did not observe any statistically significant difference in perioperative and functional outcomes in case of RASP performed with the HUGO™ RAS System and with the DaVinci® Xi System. These findings provide compelling support for considering the HUGO™ RAS as a promising tool for robot-assisted procedures, thereby expanding the utilization of robotics for benign conditions.
Robot-Assisted NephroUreterectomy (RANU) represents a minimally invasive alternative to open NephroUreterectomy (NU) for management of Upper Tract Urothelial Carcinoma (UTUC) but its oncologic safety ...is still controversial. The objective of this study was to investigate the peri-operative, pathologic and oncologic outcomes of RANU for UTUC. From 2008 to 2017, 78 patients diagnosed with UTUC and elected for RANU at 3 high-volume robotic surgery centres were retrospectively assessed. Surgery was performed using da Vinci Si
®
and Xi
®
systems. RANU was done adhering to oncological principles as in open surgery. The outcomes of the study were: (1) peri-operative morbidity, namely intra- and post-operative complications, blood loss, length of hospital stay and operative time; (2) oncologic outcomes, namely overall survival (OS) and recurrence-free survival (RFS). Peri-operative overall complication rate was 24.4% and high-grade complication rate was 2.6%. Median blood loss, length of hospital stay and operative time were 124 ml, 4 days and 167 min. Lymphadenectomy was performed in 31 (41%) patients. Lymph-node involvement was present in 9 (29%) patients. At median follow-up of 15 months, 2- and 4-year OS were 79% and 66%, respectively, and RFS was 63% and 53%. Peritoneal dissemination was recorded in 1 (1.3%) patient with pT4N2R1 UTUC. Our study is limited by the relatively small cohort of patients and its retrospective character. RANU as minimally invasive treatment for patients with UTUC is safe and feasible. Post-operative morbidity is low and major complications are rare. Oncologic outcomes are acceptable and no evidence of increased risk of peritoneal dissemination is recorded. Long-term data are needed. RANU should be regarded as an alternative to open surgery for UTUC that can offer good peri-operative and oncologic results.
