To explore and summarize the reasons why urethral calculi cause a urethral fistula.
We retrospectively studied 1 patient in Xiangya hospital and all relevant literature published in English between 1989 and 2015. The patients (including those reported in the literature) were characterized by age, origin, location of calculus, size of calculus, fistulous track, and etiological factors. Most of urethral calculi associated with a urethral fistula were native generated. Urethral calculi can be formed in various locations of the urethra, and the size of the calculus ranged from small (multiple) calculi to giant stones. The fistula external orifice located at the root of the penis was relatively common, and there were various etiological factors, such as urethral strictures, urethral trauma induced by long-term catheterization, lumbar fractures, and congenital anomaly factors. They were managed by the excision of the fistulous tract, retrieval of the urethral stones, and/or debridement and pus drainage operations.
Some elements, such as trauma, recurrent urinary tract infections, abscess formation induced by long-term catheterization, and urethral calculus, may be the risk factors for a urethral fistula.
探讨并总结尿道结石导致尿道瘘的原因。
我们回顾性研究了湘雅医院的1例患者以及1989年至2015年间发表的所有英文相关文献。对患者（包括文献中报道的患者）按照年龄、结石来源、结石位置、结石大小、瘘管及病因进行分析。大多数与尿道瘘相关的尿道结石为原发性。尿道结石可形成于尿道的不同部位，结石大小从小（多发）结石到巨大结石不等。瘘管外口位于阴茎根部较为常见，病因多种多样，如尿道狭窄、长期留置导尿管所致尿道创伤、腰椎骨折以及先天性异常因素等。治疗方法包括切除瘘管、取出尿道结石和/或清创及引流脓液手术。
创伤、反复尿路感染、长期留置导尿管引起的脓肿形成以及尿道结石等因素可能是尿道瘘的危险因素。
