Objective: Recently, holmium laser enucleation of the prostate (HoLEP) has been established as one method of endoscopic surgery for the treatment of benign prostate hyperplasia (BPH). The purpose of our study was to assess initial clinical experiences with HoLEP at our hospital.;Patients and Methods: A retrospective analysis was conducted of 28 patients with obstructive symptoms due to BPH who underwent HoLEP during the 13 months between February 2004 and March 2005.;Results: The mean age of the patients was 67.4 years (range 59 to 78 years). The mean enucleation tissue weight was 24.3 g (range 2 to 95 g), and the average operation time was 94.1 minutes (range 40 to 268 minutes). The mean duration of postoperative catheterization was 3.4 days (range 1 to 6 days). The mean urine flow rate improved, and each patient's satisfaction for voiding, measured on a 5-point scale, was good. There were no major complications during the operations except one case, which was completed with TUR-P because of uncontrollable bleeding. No patients required transfusions. Long-term complications included five cases of stress incontinence (19%), four of urethral stricture (14%), and three temporary retention, two of which required re-catheterization (10%).;Conclusion: HoLEP can be performed without major intraoperative complications. It is an effective treatment for obstructive symptoms due to BPH. However, there are many postoperative problems that must be resolved, including stress incontinence and urethral stricture because of our lack of experience, with HoLEP.

STUDY DESIGN: Retrospective cohort study. PURPOSE: To investigate the effect of spinal correction on respiratory muscle strength in patients with Duchenne muscular dystrophy (DMD). OVERVIEW OF LITERATURE: Several studies have reported that scoliosis correction in patients with DMD does not improve pulmonary function. In these studies, pulmonary function was evaluated using the traditional spirometric values of percent vital capacity (%VC) and percent forced vital capacity (%FVC). However, traditional spirometry may not be suitable for patients with DMD because the results can be influenced by patient fatigue or level of understanding. Therefore, we evaluated respiratory function focusing on respiratory muscle strength using maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and sniff nasal inspiratory pressure (SNIP), in addition to %VC and %FVC. METHODS: We retrospectively reviewed 16 patients with DMD who underwent spinal correction surgery between 2006 and 2011 at Kitasato University Hospital. All patients were males, and the mean age was 13.5 years. Respiratory muscle strength was evaluated using MIP, MEP, and SNIP. Measurements were obtained preoperatively and at 1 and 6 months postoperatively, and %VC and %FVC were obtained preoperatively and within 6 months postoperatively. RESULTS: The mean preoperative and postoperative %VC values were 54.0% and 51.7%, whereas the mean %FVC values were 53.9% and 53.2%, respectively. The mean MIP, MEP, and SNIP values obtained preoperatively and at 1 and 6 months postoperatively were as follows: MIP, 40.5, 42.7 and 47.2 cm H₂O; MEP, 26.0, 28.0, and 29.0 cm H₂O; and SNIP, 33.4, 33.0, and 33.0 cm H₂O; respectively. The mean MIP and MEP values significantly improved postoperatively. There were no significant differences in SNIP, %VC, or %FVC preand postoperatively. CONCLUSIONS: By focusing on respiratory muscle strength, our results suggest that scoliosis correction in patients with DMD might have a favorable effect on respiratory function.
