[Primary abscess of the psoas]. / Abscesos primarios de psoas.

We present in this paper a series of cases from our Service of primary abscesses in psoas. We consider the appearance of immunosuppressed patients as a relevant factor of its etiopathogenicity. We believe that a C.A.T. is the best diagnostic method. All three patients that underwent open surgery have had complications. The patients treated with percutaneous puncture has shown a favourable evolution.

[Laparoscopic radical prostatectomy. Preliminary experience]. / Prostatectomía radical laparoscópica: experiencia preliminar.

OBJECTIVE: Laparoscopic technique has been developed with the aim to decrease the morbidity of the open radical prostatectomy. MATERIAL AND METHODS: From january 2002 to may 2002, 8 patients were treated for prostate cancer with laparoscopic radical prostatectomy. Unilateral linfadenectomy has been carried out in only one patient. We usually employ the transperitoneal technique published by the Montsouris Institute, with some modifications. RESULTS: The main surgical time was 356 minutes (540-240). Transfusion wasn't needed in any case. Intraoperative complications were: 2 bladder injuries, 1 bleeding of the epigastric artery. Postoperative complications were: 1 ileus, 2 compressive neurapraxia, 4 anastomotic fistutas. All complications were treated conservatively. No patient were converted to open surgery. Surgical limits were negatifs in all cases, and the PSA rate was less than 0.1 ng/ml in the first month follow up. CONCLUSION: Laparoscopic radical prostatectomy is a difficult technique, but we think that, the learning curve is getting lower and lower than in the first series. Oncologic results with this technique is similar to the open one. However, laparoscopic approach shows us some benefits such as less bleeding, less time catheterisation, less hospital stay, better continence, better sexual function, better stetic result, less postoperative pain, and finally an earlier back to work.

[Ileal ureteroplasties]. / Ureteroplastias ileales.

When the ureter is extensively compromised, preservation of the kidney without recurring to external diversion may be attempted by a psoas bladder procedure, transureteroureterostomy, renal autotransplantation or ureteral substitution using the intestine. The first two are not always possible and transplantation is perhaps extremely disproportionate. We therefore recur to ureteral substitution using the intestine. Ureteral substitution may be partial or total, although it is recommended to preserve the upper segment of the lumbar ureter whenever possible. The procedure can be performed using the entire ileal segment with or without modelling to the appropriate thickness. Reducing the diameter of the ileal graft will enhance urine propulsion, reduce mucus secretion and improve antireflux dynamics. Nine cases of ureteral substitution are described herein. Treatment depended on the underlying pathology, extent of ureteral compromise and location. The techniques employed were ureteral substitution with or without modelling and ureteral substitution combined with a bladder repair procedure.
