Percutaneous large-bore suprapubic cystostomy catheters were placed under fluoroscopic guidance in 60 patients as an alternative to surgical cystostomy. Foley catheters (16-20 F) were placed in 57 of the patients in a one-stage procedure. Ten-French catheters were initially placed in three patients because of difficulty in dilating percutaneous tracks because of obesity (one patient) or dense scar tissue (two patients).

Preliminary data are presented of a clinically feasible pilot study to select a significant subgroup of patients among those with muscle-invading bladder tumors for local cure and bladder preservation, while also to offer all patients the possibility of preventing the development of distant metastases. Transurethral debulking surgical resection was combined with neoadjuvant methotrexate, cisplatin and vinblastine chemotherapy plus 2 additional courses of cisplatin and 4,000 cGy. If tumor was found on cystoscopic re-evaluation by biopsy and for cytology after cisplatin and partial irradiation (4,000 cGy.

A technique to insert large-bore suprapubic cystostomy catheters (18-French or larger) percutaneously, under radiologic imaging guidance, is described in 15 men who required long-term drainage of the bladder. This single-stage procedure is carried out under local anesthesia with optional IV sedation. It consists of rapid enlargement of the percutaneous track by means of a balloon dilatation catheter followed by insertion of a self-retaining Foley cystostomy catheter through a peel-away sheath.
