We identified risk factors for complications of the lower extremities related to high lithotomy positioning during specific urethral reconstruction procedures in male patients.
Records from 185 open urethroplasties were evaluated for position related complications of the lower extremities (the compartmental syndrome, rhabdomyolysis, neurapraxia). Morphometric data (patient height, weight) and surgical details (duration of surgery and lithotomy positioning, types of repair and stirrups, stricture length and location) were assessed.
In the 185 patients 18 position related complications (10%) were identified, 4 of which were severe. Univariate analysis showed length of stricture, and duration of surgery and lithotomy positioning to be statistically significant risk factors (p <0.05). Height, weight, body mass index and type of stirrups did not increase risk. Anterior end-to-end anastomosis and straightforward buccal mucosa patch grafts entailed negligible risk. Longer procedures (prostatomembranous and penile skin flap repairs) had higher complication rates (12% and 22%, respectively). Beginning penile skin flap procedures with patients in the supine position during flap harvesting followed by repositioning into high lithotomy for perineal flap transfer virtually eliminated the risk of severe complications.
The risk of position related complications during urethral reconstruction is directly proportional to the duration of high lithotomy positioning. Procedures of less than 5 hours in duration had minimal risk. For complex flap procedures, we perform penile flap dissection with the patient supine and reposition for perineal flap transfer.
我们确定了男性患者在特定尿道重建手术中与高截石位相关的下肢并发症的危险因素。
评估185例开放式尿道成形术记录中下肢与体位相关的并发症(骨筋膜室综合征、横纹肌溶解、神经失用)。评估形态学数据(患者身高、体重)和手术细节(手术时间和截石位时间、修复类型和脚蹬、狭窄长度和位置)。
185例患者中发现18例与体位相关的并发症(10%),其中4例严重。单因素分析显示狭窄长度、手术时间和截石位时间是具有统计学意义的危险因素(p<0.05)。身高、体重、体重指数和脚蹬类型不会增加风险。端端吻合术和直接颊黏膜补片移植术的风险可忽略不计。较长的手术(前列腺膜部和阴茎皮瓣修复)并发症发生率较高(分别为12%和22%)。在皮瓣采集过程中让患者仰卧位开始阴茎皮瓣手术,然后重新摆放至高截石位进行会阴皮瓣转移,几乎消除了严重并发症的风险。
尿道重建过程中与体位相关的并发症风险与高截石位时间直接成正比。手术时间少于5小时的风险最小。对于复杂的皮瓣手术,我们在患者仰卧位时进行阴茎皮瓣解剖,然后重新摆放体位进行会阴皮瓣转移。
