[A Case of Holmium: YAG Laser Resection of Superficial Bladder Tumor (HoLRBT)].

We present a case of holmium : YAG laser resection of superficial bladder tumor (HoLRBT). A 73-year-old male was referred to our hospital with elevated prostatic specific antigen. Due to difficulty of urination, holmium : YAG laser enucleation of the prostate was performed under the diagnosis of benign prostatic hyperplasia.

[Investigation of changes in sexual and ejaculatory functions after holmium laser enucleation of the prostate (HoLEP)].

Changes in sexual function and ejaculatory function in patients who had undergone holmium laser enucleation of the prostate (HoLEP) were investigated using questionnaires. In this study, 77 patients on whom HoLEP was performed at our department from July 2010 to December 2010 were included. Of the 77 patients, the number of patients who could achieve an erection increased from 36 (46.

[Relationship between morcellation efficiency and enucleated tissue weight in holmium laser enucleation of the prostate (HoLEP) for patients with benign prostatic hyperplasia].

Objective: We examined the relationship between morcellation efficiency and enucleated tissue weight in holmium laser enucleation of the prostate (HoLEP) for patients with benign prostatic hyperplasia (BPH) retrospectively.

Methods: From January to December 2010, 140 patients with BPH were treated by HoLEP combined with mechanical morcellation with up side down technique by a single surgeon.

Results: The mean age was 70.

[Holmium laser enucleation of the prostate (HoLEP) in patients with continuous oral anticoagulation: first reported cases in Japan].

Oral anticoagulation (OA) has been considered as a strict contraindication to transurethral resection of the prostate (TURP). In recent years, some studies have shown that holmium laser enucleation of the prostate (HoLEP) has less blood loss compared to TURP. Thus we have performed HoLEP in patients with benign prostatic hyperplasia (BPH) under continuous OA from September 2009, and herein we report our first nine cases.

[An effective method to shorten the learning curve of HoLEP].

Holmium laser enucleation of the prostate (HoLEP) is a safe and effective treatment for patients with symptomatic benign prostatic hyperplasia (BPH), but is a difficult operation. To shorten the learning curve, we evaluated the surgical outcome of successive bilateral lobe enucleations with HoLEP. Performed by an inexperienced endourologist and an expert.

Ammonium acid urate urolithiasis in Japan.

Aim: Ammonium acid urate (AAU) calculi are a rare urolithiasis in developed countries but are endemic in developing countries. We assessed the features of AAU urolithiasis in Japanese patients.

Methods: We reviewed hospital charts of patients with urolithiasis who were treated with extracorporeal shock wave lithotripsy and endourological procedures at Sagamidai Hospital (Kanagawa, Japan) from January 1992 to December 2001.

MOUSE MUSCLE CELL DIFFERENTIATION IN CLONAL CULTURE.

Clonal culture of muscle cells from thigh muscles of the term fetus of the mouse was undertaken. Myoblasts were spherical or spindle-shaped, and proliferated exponentially until day 4 in culture. The generation time of the muscle cells from 2 to 4 days' culture was 9.
