排尿後尿洩れ(Postmicturition dribble)の研究

Abstract

排尿後尿洩れを訴える16例につき, ビデオ録画システムを用いた排尿時尿道膀胱造影を施行し, 経時的な尿道膀胱の動態を観察した.排尿後洩れの原因は, 排尿終了後に生ずる球部尿道内残尿が座位や体の前屈などで圧迫され, 外尿道口から洩れるためである.治療は排尿終了後, 患者自身が会陰部を手指で圧迫し, 球部尿道内残尿を排出することである

Sixteen patients presenting with a symptom of postmicturition dribble were studied. All the patients were examined by the technique of voiding cysto-urethrography recording on video-tape. The findings of the videocysto -urethrography confirmed that postmicturition dribble resulted from a residue of urine in the bulbar urethra. No urodynamic abnormality was seen in the six patients who had no other symptom or disease. The patient is instructed to compress the bulbar urethra manually in the perineum after micturition and evacuate the bulbar residual urine. Symptomatic relief is usually obtained.
