摘要

手术切除是治疗局限性阴茎癌的标准治疗方法,通常在阴茎残端或会阴处建立新尿道道。新尿道经常狭窄,需要反复经尿道操作,如扩张和尿道切开术。这些手术通常是徒劳的,并且与生活质量差有关。在此,我们报告一例阴茎癌患者在全阴茎切除术后出现新金属狭窄,随后使用Blandy技术进行会阴尿道造口术。一位72岁男性被诊断为局部阴茎癌,接受了全阴茎切除术和会阴新道的创造。患者出现新尿道口狭窄,多次行尿道扩张术均未成功。最后,当患者无法排空时,他被转介给我们,通过放置耻骨上导管来改善金属狭窄。由于残余球尿道状况良好且长度足够,我们计划采用Blandy技术进行会阴非横断尿道造口术。在会阴处做一个倒u形切口,并创建一个皮瓣。完全切除球尿道远端瘢痕新道及海绵状纤维化。暴露残余球尿道,在腹侧纵切4cm。用4-0 PDS缝合裸露尿道粘膜边缘和海绵体白膜止血。将u型皮瓣的顶端引至尿道切开术的近缘,皮瓣与尿道板之间建立无张力吻合。然后,将会阴皮肤缝合到开放的纵向尿道切开术上。术后第5天患者开始排空。手术后16周,受试者可以在没有任何干预的情况下进行排尿,也不需要任何器械。

[A CASE OF NEO-MEATAL STENOSIS AFTER PENECTOMY FOR PENILE CANCER, REPAIRED BY BLANDY PERINEAL URETHROSTOMY].

Surgical resection is the standard treatment for the management of localized penile cancer and a neo-urethral meatus is generally created on the penile stump or perineum. Neo-urethral meatus is often stenosed and requires repeated transurethral manipulations such as dilation and urethrotomy. These procedures are generally futile and are associated with poor quality of life. Here, we report a case of penile cancer that developed a neo-meatal stenosis after total penectomy, which was subsequently salvaged by perineal urethrostomy using Blandy technique. A 72-year-old male who was diagnosed with localized penile cancer, underwent total penectomy and creation of neo-meatus on the perineum. Neo-meatus stenosis had developed in the patient and he received repeated urethral dilations without any success. Finally, when the patient was unable to void, he was referred to us for the amelioration of meatal stenosis through the placement of a suprapubic catheter. Because the condition of the residual bulbar urethra was adequate and its length was enough, we planned to create a non-transecting perineal urethrostomy by Blandy technique. An inverted U-shaped perineal incision was made, and a skin flap was created. The scarred neo-meatus and spongiofibrosis at the distal bulbar urethra were completely excised. The residual bulbar urethra was exposed, and a longitudinal ventral incision of 4 cm was made. The edge of the bare urethral mucosa and tunica albuginea of the corpus spongiosum were sutured by 4-0 PDS for hemostasis. The apex of the U-shaped skin flap was brought to the proximal margin of the urethrotomy and a tension-free anastomosis was created between the skin flap and the urethral plate. Thereafter, the skin of the perineum was sutured to the open longitudinal urethrotomy. The patient started to void on the 5th day post-surgery. The subject could void without the help of any intervention and did not require any instrument, sixteen weeks after the surgery.
