Influence of holmium laser enucleation of the prostate on erectile function: results of a multicentric analysis of 235 patients.

PURPOSE: Preserved sexual function is one of the endpoints of the surgical management of lower urinary tract symptoms suggestive of benign prostatic hyperplasia. Our aim was to investigate the evolution of erectile function (EF) at 3 and 12 months after holmium laser enucleation of the prostate (HoLEP). METHODS: A multicentric retrospective study was performed including 235 sexually active patients who underwent HoLEP between January 2016 and June 2017. Evaluation of EF was carried out with the five-item version of the International Index of Erectile Function (IIEF-5) completed before surgery and at 3 and 12 months after surgery. A change of more than five points in either direction in the IIEF-5 score compared to baseline was considered as an improvement or impairment of EF. RESULTS: No significant differences were found between median pre-operative IIEF-5 and median scores at 3 and 12 months (p = 0.15 and p = 0.45). At 3 and 12 post-operative months, respectively, 10% and 13% of patients reported an improvement, whereas 15% and 16% reported an impairment. The reduction in IIEF-5 score was only statistically significant within the sub-group of patients with normal pre-operative EF (p < 0.001). In this sub-group, 15% of patients reported a decrease of more than five points in total IIEF-5 score. CONCLUSION: This multicentric evaluation confirmed that median IIEF-5 score was not significantly impaired after HoLEP. However, for patients with normal pre-operative EF, a significant decrease in EF after HoLEP was observed. These results may be taken into account when counselling patients before HoLEP.

Evolution of Day-Case Holmium Laser Enucleation of the Prostate Success Rate Over Time.

Objectives: To describe the evolution of day-case success rate over the years and to identify predictive factors for prolonged hospitalization or readmissions. Methods: Retrospective review of all consecutive day-case holmium laser enucleation of the prostate (HoLEP) performed by a single surgeon between January 2013 and February 2019 using a prospective database. Day-case success was defined as discharge within less than 12 hours from admission without any readmission within 48 hours after discharge. Protocol for day-case treatment included systematic bladder catheter insertion with continuous irrigation for ∼2 hours and catheter removal on postoperative day 1. Patients were reached by phone on postoperative day 1 to ensure voiding. For the descriptive statistics, an analysis of variance was performed. Univariate and multivariate analyses were used to identify risk factors. Results: A total of 266 patients were retrieved and dispatched as follows: group 1 (n = 88) from January 2013 to July 2015, group 2 (n = 89) from August 2015 to June 2017, and group 3 (n = 89) from July 2017 to February 2019. The overall success rate was 80.5% (214/266) over the study period. It significantly improved over time from 70% in group 1 to 84% in group 2 and 87% in group 3 (p = 0.014). In the meantime, the operating time and the total energy delivered to the tissue decreased from 77 minutes in the first group to 60.4 minutes in the second group and 55.4 minutes in the third group (p < 0.001), and from 95.2 kJ in the first group to 84 kJ in the second group and 77.9 kJ in the third group (p = 0.041). On multivariate analysis, the only risk factor significantly associated with day-case failure was prostate volume greater than 90 cc (odds ratio = 2.041, p = 0.047). Conclusion: Day-case HoLEP is a reliable and safe procedure with a high success rate. The surgeon's experience seems to be crucial to improve perioperative outcomes, but prostate volume greater than 90 cc remains associated with higher failure rates.

Total Preperitoneal Robot-Assisted Kidney Transplantation.

To date, kidney transplant recipients have always undergone open surgery. The type and length of the wound vary, but most commonly, a modified Gibson's incision is made in the lower abdomen for the transplantation. Risk factors for wound complications are well defined in general surgery literature. The laparoscopic kidney transplantation (LKT) technique has been developed recently, and several teams have published studies on the intraperitoneal technique. In this case report, we present our technique of total preperitoneal LKT using the Da Vinci robotic surgical system.

Day-Case Holmium Laser Enucleation of the Prostate: Prospective Evaluation of 90 Consecutive Cases.

PURPOSE: To prospectively assess the feasibility and safety of holmium laser enucleation of the prostate (HoLEP) as day-case surgery for the treatment of benign prostatic hyperplasia. MATERIALS AND METHODS: A prospective observational study was conducted by a single surgeon between June 2012 and October 2015. Except for patients ineligible for day-case surgery due to unstable cardiovascular disease, all patients with lower urinary tract symptoms presumably due to benign prostatic hyperplasia were consecutively included. HoLEP procedures were performed at 8AM, and patients were discharged before 8PM. The urinary catheter was removed at home the following morning. The monitoring of complications related with surgery included systematic assessment of perioperative complications, phone call within 48 hours after surgery, and follow-up visits after 1 and 3 months. Intent-to-treat univariate and multivariate analysis was performed to identify risk factors for day-case surgery failure. RESULTS: Ninety among 211 HoLEP performed by the surgeon were selected for day-case surgery (43%). Hospital stay was <12 hours in 83.4% of them. Prolonged hospitalization was necessary in 15 patients mainly due to gross hematuria requiring continuous bladder irrigation (n = 13). Day-case surgery failure rate (including prolonged hospitalization and readmissions within 48 hours) was 20.0% (18/90). The overall complication rate was 36.7%, with a Clavien III complication rate of only 3.3%. Monocentric design and limited number of patients are the main limitations of this work. CONCLUSIONS: This prospective evaluation shows that day-case HoLEP may be performed by a trained surgeon with an appropriate patient selection.

Partial nephrectomy versus ablative therapy for the treatment of renal tumors in an imperative setting.

PURPOSE: To compare partial nephrectomy (PN) and percutaneous ablative therapy (AT) for renal tumor in imperative indication of nephron-sparing technique (NST). MATERIALS AND METHODS: Between 2000 and 2015, 284 consecutive patients with a kidney tumor in an imperative indication of NST were retrospectively included in a multicenter study. PN [open (n = 146), laparoscopic (n = 9), or robotic approach (n = 17)] and AT [radiofrequency ablation (n = 104) or cryoablation (n = 8)] were performed for solitary kidney (n = 146), bilateral tumor (n = 78), or chronic kidney disease (CKD) (n = 60). RESULTS: Patients in the PN group had larger tumors and a higher RENAL score. There were no differences between the two groups with respect to age, reasons for imperative indication, and preoperative eGFR. Patients in the AT group had a higher ASA and CCI. PN had worse outcomes than AT in terms of transfusion rate, length of stay, and complication rate. Local radiological recurrence-free survival was better for PN, but metastatic recurrence was similar. Percentage of eGFR decrease was similar in the two groups. Temporary or permanent dialysis was not significantly different. On multivariate analysis, PN and AT had a similar eGFR change when adjusted for tumor complexity, reason of imperative indication and CCI. CONCLUSION: In imperative indication of nephron-sparing treatment for a kidney tumor, either PN or AT can be proposed. PN offers the ability to manage larger and more complex tumors while providing a better local control and a similar renal function loss.

Learning curves and perioperative outcomes after endoscopic enucleation of the prostate: a comparison between GreenLight 532-nm and holmium lasers.

PURPOSE: To compare the learning curves, perioperative and early functional outcomes after HoLEP and GreenLEP. METHODS: Data from the first 100 consecutive cases treated by GreenLEP and HoLEP by two surgeons were prospectively collected from dedicated databases and analysed retrospectively. En-bloc GreenLEP and two-lobar HoLEP enucleations were conducted using the GreenLight HPS™ 2090 laser and Lumenis™ holmium laser. Patients' characteristics, perioperative outcomes and functional outcomes after 1, 3 and 6 months were compared between groups. RESULTS: Total energy delivered and operative times were significantly shorter for GreenLEP (58 vs. 110 kJ, p < 0.0001; 60 vs. 90 min, p < 0.0001). Operative time reached a plateau after 30 procedures in each group. Length of catheterization and hospital stay were significantly shorter in the HoLEP group (2 vs. 1 day, p < 0.0001; 2 vs. 1 day, p < 0.0001). Postoperative complications were comparable between GreenLEP and HoLEP (19 vs. 25 %; p = 0.13). There was a greater increase of Q max at 3 months and a greater IPSS decrease at 1 month for GreenLEP, whereas decreases in IPSS and IPSS-Q8 at 6 months were greater for HoLEP. Transient stress urinary incontinence was comparable between both groups (6 vs. 9 % at 3 months; p = 0.42). Pentafecta was achieved in four consecutive patients after the 18th and the 40th procedure in the GreenLEP and HoLEP group, respectively. Learning curves ranged from 14 to 30 cases for GreenLEP and 22 to 40 cases for HoLEP. CONCLUSION: Learning curves of GreenLEP and HoLEP provided roughly similar peri-operative and short-term functional outcomes.
