Open prostatectomy versus 180-W XPS GreenLight laser vaporization: Long-term functional outcome for prostatic adenomas>80 g.

INTRODUCTION: GreenLight photoselective vaporisation of the prostate (PVP) offers an endoscopic alternative to open prostatectomy (OP) for treatment of large adenomas. This study compares long-term functional outcome of both techniques in patients with Benign prostatic obstruction (BPO)>80g. MATERIAL AND METHOD: Data from patients who underwent surgical treatment for BPO>80g from January 2010 to February 2015 at our institution were retrospectively collected and compared according to surgical technique. Patient's demographics, surgeon's experience, operative data and long-term functional results were analyzed, using IPSS and International continence society (ICS) male questionnaire associated with Quality of life scores (IPSS-QL and ICS-QL). Predictors of long-term outcome were also assessed. RESULTS: In total, 111 consecutive patients, 57 PVP and 54 OP, were included in the study with a mean follow-up of 24 and 33 month respectively. Patient's age, Charlson score, preoperative IPSS and urinary retention rates were similar. Mean prostatic volume was superior in the OP group (142 versus 103g, P<0.001). Transfusion rate was lower after PVP (P=0.02), despite a more frequent anticoagulant use. Length of hospital stay and urinary catheterization were shorter after PVP (P<0.001), with however a higher rate of recatheterization (RR=4.74) and rehospitalization (RR=10.42). Long-term scores were better after OP for IPSS (1 versus 5, P<0.001), IPSS-QL, ICS, ICS-QL. On multivariate analysis, prostatic residual volume was the only predictor of long-term IPSS but not ICS. CONCLUSION: Long-term functional outcome are better after OP compared to PVP. However, PVP offers good results, allowing to safely operate patients taking anticoagulants, regardless of prostatic volume. Endoscopic enucleation may the compromise between both techniques.

Perioperative and economic analysis of surgical treatments for benign prostatic hyperplasia: A study of the French committee on LUT.

PURPOSE: To evaluate perioperative cost related to surgical treatments of benign prostatic obstruction (BPO): photoselective vaporization of the prostate (pvp), holmium/thullium laser enucleation (HoLEP/ThuLEP), transurethral resection of the prostate (TURP) and open prostatectomy (OP). MATERIAL AND METHODS: We retrospectively collected data from 237 patients who consecutively underwent a surgical treatment for BPH between January 2012 and June 2013 at nine institutions in France. An economic simulation model was constructed to estimate the cost of hospitalization related to surgical procedure from the hospital perspective and a cost minimization analysis was performed. RESULTS: TURP, OP, HoLEP/ThuLEP and PVP were performed in 99 (42%), 23 (10%), 64 (27%) and 51 (21%) patients, respectively. For men with prostate size<80mL: mean operative time was shorter with mTURP and PVP than HoLEP/thuLEP (P<0.001); Mean postoperative length of stay were 1.9, 3 vs. 3.4 days, for HoLEP/Thulep, PVP and TURP respectively (P=0.006); Costs of first hospitalization were comparable between HoLEP/ThuLEP and TURP but higher with PVP (P<0.001). For men with prostate size≥80mL: Compared to PVP and HoLEP/ThuLEP, OP was associated with shorter operative time (P<0.001) but longer length of stay (2.4, 4.2 vs. 7.8 days, respectively, P<0.0001); Costs of first hospitalization were significantly higher with OP than HoLEP/ThuLEP or PVP (P<0.001). CONCLUSIONS: PVP and HoLEP/ThuLEP were associated with a shorter LOS than TURP and OP. This benefit suggests these procedures could be more cost effective than OP, but still not cheaper alternatives to TURP. LEVEL OF EVIDENCE: 5.
