[Catheters in urology: Indications and management in daily practice for the nurse]. / Les sondes en urologie : indications et prise en charge infirmière.

The urology nurse cares for patients wearing many different types of urinary catheters. Her role in the management of these devices in external care, clinical units, operating room or at home is fundamental. We performed a state of the art of good practices and of the up to date knowledge regarding the indication, placement, and specific care of these devices, which are every day more numerous on the market. Indwelling bladder catheter are placed, daily managed and removed by nurses, depending on an initial medical indication. The type of catheter must be adapted to the patient and to the clinical situation. Its daily care and management should allow not only the best comfort for the patient, but also an efficient management of the associated infectious risk. The placement of ureteral catheters (simple monoJ, double J or nephrostomy), are mainly of surgical initial indication. We developed what we thought was compulsory knowledge about them for an operating theater's nurse. The associated care for urology's nurses is also detailed. This inventory of available urinary catheter's, of their indications and management, aims to be a help for the urology nurse in her daily practice. Her/his role is essential in the choice of the adequate catheter and in its correct management, not only for the urologist but also for the patient himself.

Long-term renal outcome in infants with congenital lower urinary tract obstruction.

INTRODUCTION: Congenital Lower Urinary Tract Obstructions (LUTO) is a heterogeneous group of diseases in which urine elimination is obstructed at the level of bladder neck or urethra. The aim of the study is to evaluate the long-term renal outcome of patients suffering of congenital LUTO. PATIENTS AND METHOD: We retrospectively reviewed patients with congenital LUTO. All patients had at least 1 year follow-up. Data on surgery, renal imaging and Schwartz estimate creatinine clearance were collected. Incidence of Chronic Renal Disease (CRD) is presented with Kaplan-Meier method. RESULTS: 40 patients were included, 23 patients with Posterior Urethral Valve (PUVs) and 17 patients with other aetiologies: anterior urethral valve (2), urethral atresia (2), urethral stenosis (2), cloacal malformations (2), obstructive ureterocele (1), bladder trigone malformation (1) and neonatal bladder-sphincter dysfunction without neurological abnormalities (7). Incidence of CRD at age 10 years was 37% in congenital LUTO, 42% in PUVs and 30% in other aetiologies, and was significantly higher in PUVs (P=0.032). Renal prognosis was significantly worsened by discover of retentional bladder wall changes in initial cystoscopy, and by loss of parenchymal differentiation or cortical microcysts in first ultrasonography. The use of urinary diversion was significantly higher in LUTO of other aetiologies. CONCLUSION: A high incidence of CRD is observed in patients with congenital LUTO, significantly higher in patients with PUV. LUTO of other aetiologies require step by step surgical management and higher use of urinary diversion. Precise initial evaluation in cystoscopy and ultrasonography is required and participate to evaluate future renal outcome. LEVEL OF INCIDENCE: 4.
