Serial renal transplant surgery: technical reflections concerning third transplants.
From 1972 to 1993, we carried out 803 consecutive renal transplants including 8 third transplants. Exclusively cadaveric, these third renal transplants were implanted by intraperitoneal approach in right iliac position, without previous homolateral transplantectomy in 5 cases. The arterial anastomoses were common (7) or external iliac and hypogastric (1), and the venous anastomoses external (1) and common iliac (3), or inferior vena cava (4). Restoration of urinary continuity was by ureteronecystostomy (Politano-Leadbetter = 4, Grégoir-Lich = 3) or ureteroureteric anastomosis (1). The level of HLA compatibility varied from 2 to 5 identities (mean 3.1) and 4 of the 7 patients explored were hyperimmunized with lymphocytotoxic antibody levels > or = 80%. With the exception of the first of these third transplants, the immunosuppressive protocol associated azathioprine, prednisolone, antilymphocytic serum and cyclosporin. Postoperative sequels were marked by 3 vascular rejections and 1 death from hyperkalemia. Moreover, 1 urinary fistula on ureteroureteric anastomosis settled after percutaneous nephrostomy and placing of an uteric stent endoprosthesis. With a postoperative follow-up of 8-32 months (mean 24), 5 of the transplanted patients (62.5%) have a functional renal transplant with a serum creatinine from 120 to 180 microM/l (mean 140). This brief series, whose failures are exclusively immunological, reveals the remarkable technical reliability for these third renal transplants in right iliac implantation, by median transabdominal approach and above a former transplant site.

[Treatment of sexual impotency by intra-cavernous injections of prostaglandin E1. Report of 180 patients].
As already reported, PGE1 induces a valid erection, when administered intracavernously, without causing prolonged erection or general side effects. We have tested PGE1 (< 20 micrograms) in 180 patients suffering from organic erectile impotence, a complete erection was observed in 130 (72.2%), while incomplete erection was noted in 37 (20.5%). In both groups (92.7%) erection was sufficient for sexual intercourse. Among the best results, 41 patients had previously received high doses intracavernous injection of papaverine, without any benefit, and 15 patients have cavernosal venous leakage documented by cavernosometry and cavernosography before prostaglandin E1 test. Tumescence without rigidity was noted in 13 (7.2%). Of these 167 patients, 95 entered an autoinjection protocol for treatment of erectile dysfunction, using special device. In our series neither systemic reaction nor prolonged erection occurred. No fibrosis of cavernous tissue or scar formation was observed after up to 125 injections. However, 19 patients (10.5%) reported burning sensations during the entire period of erection and one patient (0.5%) had an haematoma at the site of the injection. PGE1 is effective in inducing artificial penile erection and it has a role in the diagnosis and treatment of erectile dysfunction, it is considered to be a more suitable agent than other vasoactive drugs.

Timing of antibiotic prophylaxis with cefotaxime for prostatic resection: better in the operative period or at urethral catheter removal?
There are two critical moments for the development of severe infectious complications following transurethral prostatectomy (TURP): the operative and immediate postoperative periods, and the day that the postoperative drainage catheter is removed. To optimize the timing of antibiotic prophylaxis with cefotaxime, two prospective randomized studies were conducted in patients with preoperatively sterile urine. In Study 1, all patients (n = 50) received cefotaxime 1 g intramuscular (i.m.) 1 hour preoperatively and were then randomized to receive either a second identical dose of cefotaxime 1 hour before catheter removal 24 hours later, or no further antibiotic treatment. In Study 2, patients (n = 89) were randomized to receive either cefotaxime 1 g i.m. 1 hour preoperatively or no preoperative antibiotic, after which all received cefotaxime 1 g i.m. 1 hour before catheter removal. Results were compared using identical evaluation criteria for infection in both studies: incidence of fever (temperature > 38 degrees C), bacteriuria (10(5) organisms/mL) and positive blood cultures, and duration of hospital stay (days). In Study 1, infection was significantly reduced with respect to all parameters in the group receiving two doses of cefotaxime, and total drug treatment costs were halved. In Study 2, the groups did not differ with respect to any parameter. We conclude that a single dose of cefotaxime 1 g i.m. 1 hour preoperatively provides inadequate cover for urethral catheter removal 24 hours later, and that prophylaxis with a single dose of cefotaxime 1 g i.m. 1 hour before catheter removal is just as effective as two doses given 1 hour preoperatively and 1 hour before catheter removal. Prophylactic coverage is essential during the action of removing the catheter and the time immediately following the operation. Long-term antibiotic coverage (24 hours or more) is not necessary. Thus, following TURP in patients with preoperatively sterile urine undergoing continuous bladder irrigation for 24 hours postoperatively, the optimal dose schedule for antibiotic prophylaxis with cefotaxime is a single 1-g dose given i.m. 1 hour before catheter removal.

[Conversion laparatomies during cholecystectomies under laparoscopy. Apropos of 285 consecutive cholecystectomies].
Retrospective analysis of a consecutive series of 285 cholecystectomies carried out by laparoscopy showed that 47 patients (17.5%) required conversion laparotomy. In 55% of these cases the conversion was due to difficulty in dissecting the gallbladder or cystic duct. Peri-operative cholangiography should be performed routinely, not only to verify the vacuity of the common bile duct (13% of the conversions) but, more particularly, to ensure the integrity of the principal biliary pathway during the dissection (8.5% of the conversions). Cholecystectomy under celioscopy is a proven and safe technique, on the condition that all stages of classical surgery can be carried out under good conditions.
