A congenital bladder diverticulum (CBD) is caused by inherent muscular weakness instead of obstruction of the bladder outlet. The major clinical conditions are recurrent urinary tract infection (UTI) and voiding dysfunction. This report describes a 15-year-old male adolescent who developed sudden visual disturbance resulting from hypertensive retinopathy. The cause of hypertension was bilateral obstructive uropathy caused by enlarged paraureteral bladder diverticula. After the non-functioning right kidney and ureter and the bilateral diverticula were removed, the left ureter was reimplanted in the bladder. Pathologic findings showed chronic pyelonephritis and partial loss of the bladder musculature in the diverticular wall. This observation indicates that dilated CBD can cause latent UTI, ureteral obstruction, hydronephrosis, and secondary hypertension.
先天性膀胱憩室（CBD）是由固有肌肉无力引起的，而不是由膀胱出口梗阻引起的。主要的临床情况是反复尿路感染（UTI）和排尿功能障碍。本报告描述了一名 15 岁男性青少年，他因高血压性视网膜病变而突然出现视力障碍。高血压的原因是双侧输尿管旁膀胱憩室增大导致的梗阻性尿路梗阻。在切除无功能的右肾和输尿管以及双侧憩室后，左侧输尿管被重新植入膀胱。病理检查显示慢性肾盂肾炎和憩室壁部分膀胱肌肉丧失。这一观察结果表明，扩张的 CBD 可导致潜伏性 UTI、输尿管梗阻、肾积水和继发性高血压。
