There have been few reported cases of ureteral diverticula less than 4 mm in diameter; these are best described as pseudodiverticula based on their appearance in specimens obtained for pathologic study. An additional 23 patients are reported, 15 of whom were examined by urinalysis, urine culture, cystoscopy, and cytologic studies of the urine. Cytologic findings are of interest because of previous reports suggesting an association between ureteral diverticula and transitional cell carcinoma in the urinary tract. Hematuria, transitional cell carcinoma, and benign prostatic hyperplasia were the most common presenting conditions. Infection was found in only three. Diverticula were multiple in 91%, bilateral in 69%, and were predominantly upper and midureteral in location. Urine cytologic studies failed to detect early uroepithelial malignancy, but nonspecific cellular atypia and an association with malignancy in 30% of these patients suggests that close follow-up of patients with ureteral pseudodiverticulosis is prudent.
据报道，直径小于4毫米的输尿管憩室病例很少；根据病理研究标本中的表现，这些最好被描述为假性憩室。本文报告了另外23例患者，其中15例接受了尿液分析、尿培养、膀胱镜检查和尿液细胞学研究。由于之前有报道提示输尿管憩室与泌尿道移行细胞癌之间存在关联，因此细胞学检查结果备受关注。血尿、移行细胞癌和良性前列腺增生是最常见的临床表现。仅3例发现有感染。憩室多发的占91%，双侧的占69%，主要位于输尿管上段和中段。尿液细胞学检查未能检测出早期尿路上皮恶性肿瘤，但这些患者中有30%出现非特异性细胞异型性且与恶性肿瘤有关联，这表明对输尿管假性憩室病患者进行密切随访是明智的。
