[Retroperitoneal laparoscopic pyeloplasty: retrospective study of 45 consecutive adult cases].

Prog Urol 2006 Sep;16(4):439-44

Service d'Urologie-Andrologie, CHU de Saint-Etienne, France.

Objective: To evaluate the results of retroperitoneal laparoscopic surgical repair of ureteropelvic junction (UPJ) syndrome.

Material And Methods: Retrospective study of 45 consecutive Küss-Anderson-Hynes laparoscopic pyeloplasties performed over a 4-year period (December 1998-November 2002) in adults (26 women, 19 men) with a mean age of 44.8 years (range: 16-83 years).

Results: The mean operating time was 138 minutes (range: 75-250 minutes). Open conversion was necessary in 3 cases: necrotic pyelitis, ectopic renal artery, posterior pelvic tear. The mean hospital stay was 6.1 days. With a mean follow-up of 19 months (range: 3-58 months), the clinical success rate was 97.6% and the success rate on IVU or scintigraphy was 83.3%.

Conclusion: This series confirms that laparoscopic pyeloplasty is a minimally invasive technique that gives better results than those of the various endopyelotomy techniques and equivalent results to those of open pyeloplasty with decreased morbidity.

[Management of blunt trauma of the kidney].

Prog Urol 2004 Sep;14(4):461-71

Service d'Urologie et de la Transplantation renale, Centre Hospitalierm Universitaire de Grenoble, France.

The current management of blunt trauma of the kidney is based on the 5-grade classification of lesions established by the ASST (American Society of the Surgery of Trauma). The indications for imaging are now clearly defined and spiral CT represents the reference examination. Over the last decade, the debate concerning the management of severe trauma has divided the supporters of surgical treatment from those who recommended conservative management. The contribution of interventional radiology and endourological treatments and the efficacy of intensive care now limit the complications related to trauma and reduce the need for surgery. However, the morbidity related to trauma is considerable in the presence of fragments of devascularized renal parenchyma, urine extravasation and associated lesions. These complications can be anticipated by a better definition of the traumatic lesions. The American classification presents certain limitations in relation to these combinations of poor prognostic factors. This review was designed to define the most recent biomechanical considerations, the place of imaging and finally the indications and results of management of blunt trauma of the kidney, in the light of the data of the literature.

[Use of MEOPA (nitrogen monoxide-oxygen mixture) as analgesic for prostate biopsies].

Prog Urol 2004 Dec;14(6):1167-70

Service de Chirurgie Urologique et de la Transplantation rénale, CHU de Grenoble, France.

Objective: To determine the tolerance of prostate biopsies in the case of co-administration of an analgesic gas composed of a ready for use mixture of nitrogen monoxide and oxygen (MEOPA) (marketed under the trade name of Kalinox), and intrarectal instillation of xylocaine gel by comparing the results with those obtained in a control group only receiving intrarectal xylocaine instillation.

Material And Methods: Non-randomized, prospective study conducted on 100 cases, with a control group composed of the first 22 patients (before availability of MEOPA in the department), followed by 78 patients treated with MEOPA. A questionnaire was completed by the patient and by the outpatient nurse caring for the patient.

Results: A very significant reduction (p=0.003) of the VAS pain score (from 3.86 to 2.38) and a highly significant improvement (p<0.001) of global tolerance of the procedure based on the nurse's estimation of pain (VAS scale) were observed. The MEOPA group also presented a significant improvement of pain in patients who had previously undergone a series of prostate biopsies (p=0.043). The satisfaction rate was higher in patients receiving MEOPA, although 28.2% of patients experienced adverse effects, all minor and bothersome in only 3.81% of cases.

Conclusion: The MEOPA analgesic method as a complement to intrarectal xylocaine instillation considerably improved tolerance of the procedure with no major adverse effects and without prolonging the procedure or the surveillance. It is simple to use, safe and effective.
