INTRODUCTION: We tried a complete detachment of the whole prostate lobes for benign prostate hyperplasia (BPH) by transurethral enucleation of the prostate (TUE). The feasibility of a new modified TUE technique (transurethral detaching prostatectomy = TUDP) was assessed by retrospective analysis. MATERIALS AND METHODS: For 46 BPH cases the whole prostate lobes were detached from the surgical capsule completely by a prostate-detaching blade and resectoscope beak, and dropped into the bladder. The detached prostate lobes were removed by a soft tissue morcellator. The preoperative total prostate and adenoma volume by transabdominal ultrasound measurement (TAUS) were 47.75 +/- 25.63 and 27.8 +/- 17.33 ml. RESULTS: In all 46 BPH cases, the whole prostate lobes could be detached completely without a perforation. Transurethral resection (TUR) syndrome and blood transfusion were not seen. Operation time was 54.28 min. The mean of removed tissue weight, that of hemoglobin loss and that of decrease of serum sodium was 37.11 g, 1.65 mg/dl and 1.56 mEq/l, respectively. Postoperative prostate volume and PSA were decreased to 9.56 ml and 0.8 ng/ml with complete removal of an adenoma. CONCLUSIONS: TUDP could achieve complete removal of even a large adenoma without perforation, transurethral resection syndromes and blood transfusion safety.
