Percutaneous balloon dilatation of a mid-ureteric obstruction caused by retroperitoneal fibrosis

Follow-up of a case of retroperitoneal fibroses treated sequencially via right side autotransplant and left uterolysis with wrapper of posterior preperitoneal fat

We present a case of retroperitoneal fibrosis treated with a renal autotransplantation in a patient inicially treated with endourologic measures and corticotherapy without success. The extense ureteral affectation was the indication to carry out an autotransplant. The follow-up is of nine years, with the function of the renal unity still preserved. We checked the literature for the therapeutic possibilities, medical as much as surgical, of the retroperitoneal fibrosis with special attention to the usage of the refractory IRF to other treatments.

Idiopathic retroperitoneal fibrosis revisited

We have evaluated 21 patients, ranging in age from 44 to 71 years (mean: 55 years), who presented to our department with the radiologic characteristics of retroperitoneal fibrosis. Ureterolysis was performed in all cases. Intraperitoneal placement of the ureter was performed in 9, and placement of the ureter in a lateral extraperitoneal position in 12 cases. We found no difference in the postoperative course and radiological and clinical improvement to favour the first or the second method, and therefore we consider the intraperitoneal approach as an unnecessary manoeuvre.

La fibrosi retroperitoneale idiopatica. Presidi mini-invasivi: Idiopathic retroperitoneal fibrosis. Minimally invasive devices

Some endoscopic percutaneous techniques are described that are useful both in the diagnosis and therapy of retroperitoneal fibrosis. These techniques allow urinary drainage, easily resolving an acute episode, and may be a temporary solution in patients who should respond to medical therapy. They may be considered a final therapy in patients who cannot be operated.

Ureterolysis for extrinsic ureteral obstruction: a comparison of laparoscopic and open surgical techniques

PURPOSE

We evaluated the role of laparoscopy in the management of extrinsic ureteral obstruction due to benign retroperitoneal fibrosis or ovarian pathology. The results of laparoscopic ureterolysis were compared to those of a contemporary series of open ureterolysis performed for the same pathological conditions.

MATERIALS AND METHODS

We compared 6 patients undergoing unilateral laparoscopic ureterolysis for extrinsic ureteral obstruction to 7 undergoing open unilateral ureterolysis for similar pathological conditions. Patient demographic, operative, and early and late postoperative data were collected.

RESULTS

Laparoscopic ureterolysis was associated with less intraoperative blood loss and need for parenteral pain medications, and significantly shorter hospital stay and convalescence than open surgery. Although there were no intraoperative or postoperative complications in the laparoscopy group, 1 patient in the open surgery group had an intraoperative ureteral avulsion and 4 had minor postoperative complications (blood transfusion, ileus and/or wound cellulitis). Operative time was longer in the laparoscopy group (255 versus 232 minutes). Subjective followup with an analog pain scale and/or telephone interview showed improvement in all patients in the laparoscopy group and all 6 contacted in the open surgery group. Likewise, excretory urography and/or renal scan showed improved renal function and relief of obstruction in all patients.

CONCLUSIONS

Laparoscopic unilateral ureterolysis for extrinsic ureteral obstruction is a less morbid, yet equally effective procedure with several clinical advantages over conventional open surgical ureterolysis.
