[Spontaneous rupture of endo-ureteral catheter]. / Rotura espontánea de catéter endourológico.

A patient with bilateral staghorn calculi treated by ESWL and endourologic placement of a double-J catheter is described. The patient was lost to follow-up for 18 months after catheter placement. When the patient was seen again, examination revealed a fractured catheter which warranted retrieval by combined nephrectomy and URS.

[Endoscopic injection of autologous adipose tissue in the treatment of female incontinence]. / Inyección endoscópica de tejido graso autólogo en el tratamiento de la incontinencia femenina.

We describe a new procedure utilizing autologous fat instead of teflon injection in the treatment of female urinary incontinence that is equally useful in correcting postadenomectomy incontinence in the male and vesicoureteral reflux. We have used this new procedure over the past 4 months in 10 patients with urinary stress incontinence and no concomitant cystocele. The procedure is performed under spinal anesthesia. Small cylinders of subcutaneous abdominal fatty tissue are obtained by microliposuction. The fat graft in the form of four 10 ml. wheals is then injected in the vesical neck. We emphasize that this technique is simple and there are no complications. The low cost of this technique requiring a 24 h stay at the hospital affords additional advantages. Likewise, the procedure can be repeated or subsequent surgical procedures can be performed without difficulty in the event correction is unachieved.
