Prostatic-type polyps are uncommon lesions in the urinary tract. They are sometimes found in the lower urinary tract, particularly on the posterior urethra, but are rarely found in the bladder. We report a case of 15-year-old boy who presented with dysuria. Routine ultrasonography showed a mass in the bladder arising near the internal orifice of urethra. Further inspection with cystoscopy followed by transurethral resection and pathology confirmed the lesion to be a prostatic-type polyp. An overview of other similar case studies showed that the pathogenesis of this condition is controversial, haematuria and dysuria are common clinical symptoms and endoscopic transurethral resection is the best treatment option. Since the polyp is benign, recurrence and progression of this disorder is unlikely to occur.
前列腺型息肉是泌尿道中少见的病变。它们有时出现在下泌尿道，特别是后尿道，但很少见于膀胱。我们报告一例15岁男孩，他因排尿困难就诊。常规超声检查显示膀胱内靠近尿道内口处有一肿物。随后经膀胱镜进一步检查，接着行经尿道切除术及病理检查，证实该病变为前列腺型息肉。对其他类似病例研究的综述表明，这种疾病的发病机制存在争议，血尿和排尿困难是常见的临床症状，内镜下经尿道切除术是最佳治疗选择。由于息肉是良性的，这种疾病不太可能复发和进展。
