Although cystolitholapaxy is possible in children, the instruments are not available everywhere. For tiny impacted urethral stone, an alternate technique is described.
A 3-year-old boy came with retention of urine and dysuria. On examination: bladder was full, suprapubic region was tender, and a stone could be felt at posterior urethra. We planned push back and suprapubic cystolithotomy. After general anesthesia, the stone was pushed back by instillation of lignocaine jelly into the urethra. Then, a cystoscope was introduced, and a stone was found inside the urinary bladder. Under cystoscopic view, a 5 mm laparoscopic port was inserted into the bladder just above the pubic symphysis in the midline. A 5 mm tissue holding forceps was introduced through this port, and the tiny stone was grasped and brought out along with the port. The port site was closed by a single stitch. A penile catheter was kept for 5 days.
The boy did well in the postoperative period, and voiding was normal after removal of the catheter.
Impacted posterior urethral stone can be retrieved by simple percutaneous technique.
尽管小儿膀胱结石碎石术可行,但并非各地都有相应器械。对于微小嵌顿性尿道结石,本文描述了一种替代技术。
一名3岁男孩因尿潴留和排尿困难前来就诊。检查发现:膀胱充盈,耻骨上区压痛,后尿道可触及结石。我们计划将结石推回并进行耻骨上膀胱切开取石术。全身麻醉后,通过向尿道内注入利多卡因凝胶将结石推回。然后,插入膀胱镜,在膀胱内发现结石。在膀胱镜直视下,于耻骨联合上方中线处将一个5毫米的腹腔镜端口插入膀胱。通过该端口插入一把5毫米的组织钳,夹住微小结石并随端口一起取出。端口部位用单针缝合关闭。留置阴茎导尿管5天。
该男孩术后恢复良好,拔除导尿管后排尿正常。
嵌顿性后尿道结石可通过简单的经皮技术取出。
