Abstract

In a difficult environment like surgery with continuous exposure to stress, surgeon's health and well-being is affected. The heart rate variability (HRV) is a valid stress indicator. This study aims to provide descriptive data regarding stress during urological intervention using HRV.

Abstract

International audience; INTRODUCTION: Urinary stones are relatively frequent in pregnant women and raise specific diagnostic and therapeutic problems. The authors conducted a retrospective review of the management of this disease in their establishment. PATIENTS AND METHODS: Between January 1999 and December 2003, out of a total of 10,398 parturients, 48 pregnant women were hospitalised for renal colic, that is, incidence of 0.04%. The medical records of these patients were retrospectively reviewed and clinical, laboratory, treatment and outcome data were analysed. RESULTS: Standard analgesic treatment, comprising paracetamol and an antispasmodic, achieved pain relief in 84% of cases. A concomitant short course of corticosteroid therapy in cases of renal colic refractory to standard treatment was effective in 71% of patients and allowed deferral of surgical management in five out of seven cases. A double J stent was placed in all patients requiring urinary diversion, followed by closer ultrasound and bacteriological monitoring throughout pregnancy. Only two patients required surgical management of their stone after delivery. The only obstetric event related to renal colic was induction of labour at term in two cases because of foetal distress. CONCLUSION: The authors propose a two-stage management plan for renal colic in pregnant women resulting in a low maternal and foetal complication rate.

Abstract

International audience; OBJECTIVE: To evaluate the complications, the morbidity and mortality of renal transplantation in patients with a vascular prosthesis inserted either prior to or at the same time as renal transplantation. PATIENTS AND METHOD: Between January 2001 and January 2006, six renal transplantations were performed in patients with arterial vascular prostheses or requiring concomitant insertion of a vascular prosthesis during renal transplantation. The mean age was 58 years [range: 47-69 years]. In each case, we evaluated operative difficulties, complications and postoperative course (morbidity, mortality) and the renal functional result. RESULTS: The mean operating time was 230 minutes [range: 130-380 minutes] with a mean blood loss of 390 ml [175-750 ml]. Three patients required another surgical operation for femoral thrombosis, iliofemoral thrombosis and compressive haematoma. The median length of hospital stay was 21 days [range: 9-78 days]. Graft function was restored immediately in all six patients, and one case of graft loss was observed. The morbidity was higher than that usually observed after renal transplantation. With a mean follow-up of 26 months, the vascular and renal results are satisfactory. CONCLUSION: Renal transplantation in patients with a history of vascular prosthesis or requiring replacement of the vascular prosthesis at the same time as renal transplantation can be performed with satisfactory results but with an increased morbidity. The vascular treatment must be part of a multidisciplinary strategy in the context of transplantation.

Abstract

Purpose: The aim of the study was to analyze results and morbidity after flexible ureterorenoscopy in patients with a body mass index (BMI) >30 kg/m2 and to compare with results obtained in a large cohort of nonobese patients. Patients and Methods: We conducted a retrospective study including all flexible ureterorenoscopy performed for stone retrieval in our institution between January 2004 and December 2008. During the study period, 224 procedures were performed, of which 18 had to be excluded because of missing BMI data. Thus, a total of 206 procedures were included in the final analysis (34 in 29 obese patients, 172 in 149 nonobese patients). Characteristics of the patients (age, BMI, previous treatment), stones (nature, location, number), and procedures (operating time, morbidity, outcome) were analyzed. Success was defined as clear imaging (completely stone free) on renal tomography and ultrasonography at 1, 3, and 6 months follow-up. Results: Mean BMI was 34±0.6 kg/m2 in obese patients (OP) and 24±0.2 kg/m2 in nonobese patients (NOP). Mean stone size, location, and composition were not significantly different between groups. Operative time was also similar in OP and NOP (102.5±6.1 min vs 103±3.4 min, P=NS). The rate of minor complications (fever, hematuria, flank pain) was similar in OP (11.8%) and NOP (11.4%). No major complication necessitating prolonged hospital stay or new surgical procedure was observed. The overall stone-free rate was not significantly different between OP (79.4%) and NOP (70%). Conclusion: Flexible ureterorenoscopy is an appropriate treatment for use in obese patients and achieves excellent stone-free rates with low morbidity. [ABSTRACT FROM AUTHOR]

Abstract

Priapism is a rare disease that can be secondary to a clotting disorder. The authors report the first published case of priapism due to a heterozygous mutation of factor V Leiden responsible for activated protein C resistance in a patient treated with low molecular weight heparin. A similar case has already been reported, but with a homozygous mutation. Priapism must therefore be considered to be a thromboembolic event and the presence of a clotting disorder should be systematically investigated in the absence of an obvious aetiology.
