A case of diverticular stones in the male anterior urethra with retrocaval ureter is reported. A 26-year-old man visited our hospital for examination, who had experienced spontaneous stone discharge a few days earlier. Computed tomographic (CT) scan with ureteral catheterization and urethrography revealed a retrocaval ureter and urethral diverticular stones. Resection of urethral diverticulum with 7 stones and right ureteroplasty were performed. The urethrography and drip infusion pyelography (DIP) 9 months after operation showed no abnormal findings. The largest stone was 28 x 22 x 20 mm in size and 20 g in weight. The main components were ammonium dihydrogen-urate (70%), carbonate apatite and struvite. Histological feature of the epithelium of the urethral diverticulum indicated normal skin with hairs. Pathological diagnosis was para-urethral dermoid cyst. Our case is the 67th case of the male urethral diverticular stones and the first case of those with retrocaval ureter in Japan.

A case of a 45-year old woman with an ovarian dermoid cyst causing ureteric colic secondary to distal ureteral obstruction is reported. The dermoid cyst was observed on computed tomography to be adjacent to and compressing the distal left ureter and this was confirmed at surgical exploration. Following oophorectomy, the patient's symptoms completely resolved and the excised ovarian cyst was confirmed on pathological evaluation to be a dermoid cyst. This appears to be the first reported case of ureteral obstruction caused by an ovarian dermoid cyst in the English medical literature.
