Complications of laser prostatectomy: a review of recent data

Introduction: Laser techniques for the treatment of bladder outlet obstruction (BOO) due to benign prostate enlargement (BPE) have emerged as an alternative to transurethral resection of the prostate (TURP) and open prostatectomy (OP). Materials and methods: A Medline search over the past 4years was performed to assess the safety, intra- and postoperative morbidity of various laser techniques. Results: Data on holmium laser enucleation of the prostate (HoLEP) show the highest grade of evidence with two meta-analyses available and prove the low intra- and postoperative morbidity with reproducible long-term results. Photoselective vaporization of the prostate (PVP) with the Greenlightlaser (potassium titanyl phosphate, KTP or lithium borate, LBO) is characterized by excellent haemostatic properties in patients with or without oral anticoagulation. Long-term results show a reoperation rate comparable with TURP; however, there is a lack of randomized trials. Various types of diode lasers with different wavelengths are available for laser vaporization; despite their favourable haemostatic properties, a higher invasion depth seems to result in necrosis of the tissue leading to a higher rate of reoperation. Thulium-laser resection of the prostate shows promising intra- and postoperative morbidity, but data are limited and initial results need to be confirmed in large-scale trials. Conclusion: In summary, HoLEP- and KTP-, or LBO-laser vaporization of the prostate are the most mature techniques of laser prostatectomy and treatment alternatives to TURP and OP, whereas the clinical value and durability of procedures with diode laser systems and the thulium laser need to be confirmed in high-quality prospective RCT

Patients' perception of surgical outcomes and quality of life after retroperitoneoscopic and open pyeloplasty

PURPOSE To report postoperative health-related quality of life (HRQoL) and patients' subjective evaluations of open pyeloplasty (OP) and retroperitoneoscopic pyeloplasty (RP) and influences on preoperative counselling. METHODS 107 patients (age 16-80 years, mean 31.5) with symptomatic primary ureteropelvic junction obstruction who underwent OP (32) or RP (75) were evaluated prospectively. HRQoL was evaluated using Short Form 36 (SF-36) questionnaires with 1 year follow-up. Operative outcomes were evaluated using a self-designed questionnaire regarding cosmetic outcomes, objective postoperative/current pain, convalescence and return to work. RESULTS The mean operative time was 174.4 vs. 161.4 min for RP versus OP, respectively, without intraoperative complications/conversions. There was an advantage for RP--except for two domains--without significance in any of the eight SF-36 domain scores. An advantage favouring RP in all aspects of the second questionnaire with significance in four aspects (cosmetic results, scar length, pain and convalescence) was found. Five weeks postoperatively, 58.7% (RP) vs. 25.8% (OP) were fully convalescent compared to 87.0% (RP) vs. 71.0% (OP) at 8 weeks. Similarly, 58.7 vs. 45.1% returned work 5 weeks postoperatively while 93.5 vs. 74.2% did so after 8 weeks, respectively. The small sample size, more questions on satisfaction/regret and mixed design are the main study limitations. CONCLUSION RP provides the same functional results beside earlier convalescence, better HRQoL and patients' convenience with surgery, which favours its inclusion in preoperative counselling providing patients with realistic postoperative expectations
