膀胱疝氣是一個很少被正確診斷的疾病，本院在民國七十六年五月至七十七年六月冒，共治療七個病患，僅佔同時期腹股溝疝氣患者的0.9%，與一般文獻所估計的10%相去甚遠，除了疝氣本身多半不大之外，臨床醫師的警覺性不夠，也是原因之一。病患主訴多半為非特異性症狀，一例有典型的兩段式排尿。手術前正確診斷的有四例，主要依據立姿經靜脈腎盂攝影或膀胱攝影檢查。三例因疝氣手術中誤傷膀胱而發現。依分類，三例為腹膜側型，二例為腹膜外型，一例無法判斷，一例未接受手術。治療方法為將膀胱疝氣復位，或部分膀胱切除，加上疝氣修補術。

Herniation of urinary bladder is not an uncommon disease. In our series, it occurs in 0.9% of all inguinal hernia in men over 50 years of age. From May 1987 to June 1988 we had treated 7 bladder Hernia, only one patient had the typical “two-stage urination,” the others were nonspecific complaints. According to standing IVP films or cystogram, 4 patients were diagnosed correctly before operation, the other three were found unexpectedly after injury of unrinary bladder during hernioplasty. According to the classification, there were 3 paraperitoneal, 2 extraperitoneal type herniations, one cannot be identified druing operation and one cannot be identified during operation and one patient did not receive surgical intervention. The treatment consists of reduction of herniated bladder. With or without partial cystectomy, and hernioplasty.
