Secondary urethral stone although rare, commonly arises from the kidneys, bladder or are seen in patients with urethral stricture. These stones are either found in the posterior or anterior urethra and do result in acute urinary retention. We report urethral obstruction from dislodged bladder diverticulum stones. This to our knowledge is the first report from Nigeria and in English literature.
A 69 year old, male, Nigerian with clinical and radiological features of acute urinary retention, benign prostate enlargement and bladder diverticulum. He had a transurethral resection of the prostate (TURP) and was lost to follow up. He re-presented with retained urethral catheter of 4 months duration. The catheter was removed but attempt at re-passing the catheter failed and a suprapubic cystostomy was performed. Clinical examination and plain radiograph of the penis confirmed anterior and posterior urethral stones. He had meatotomy and antegrade manual stone extraction with no urethra injury.
Urethral obstruction can result from inadequate treatment of patient with benign prostate enlargement and bladder diverticulum stones. Surgeons in resource limited environment should be conversant with transurethral resection of the prostate and cystolithotripsy or open prostatectomy and diverticulectomy.
继发性尿道结石虽然罕见,但通常源于肾脏、膀胱,或见于尿道狭窄患者。这些结石位于后尿道或前尿道,可导致急性尿潴留。我们报告了由膀胱憩室结石移位引起的尿道梗阻。据我们所知,这是尼日利亚和英文文献中的首例报告。
一名 69 岁的尼日利亚男性,具有急性尿潴留、良性前列腺增生和膀胱憩室的临床和影像学特征。他曾接受经尿道前列腺切除术(TURP),但失访。他再次出现留置导尿管 4 个月。导尿管被取出,但再次尝试导尿失败,随后进行耻骨上膀胱造口术。阴茎的临床检查和普通 X 线片证实存在前尿道和后尿道结石。他接受了尿道切开术和逆行手动取石术,没有尿道损伤。
对患有良性前列腺增生和膀胱憩室结石的患者治疗不充分可能导致尿道梗阻。资源有限环境中的外科医生应熟悉经尿道前列腺切除术和膀胱碎石术,或开放性前列腺切除术和憩室切除术。
