ABSTRACT

OBJECTIVE: To evaluate the safety and efficacy of a procedure using surgeon-tailored polypropylene mesh (STM) through a needle-less single-incision technique for treating stress urinary incontinence (SUI), aiming to decrease the cost of treatment, which is important in developing countries. PATIENTS AND METHODS: In all, 43 women diagnosed using a cough stress test were treated from January 2011 to June 2013 at the Urology and Gynaecology Departments (dual-centre), Cairo University Hospitals. Previous surgery was not a contra-indication. Patients with a postvoid residual urine volume of >100 mL, a bladder capacity of <300 mL, impaired compliance or neurological lesions were excluded. The Stress and Urge incontinence Quality of life Questionnaire (SUIQQ) and urodynamic variables were compared before and after surgery. The variables were compared between the baseline and postoperative follow-up values using a paired t-test, a Wilcoxon signed-rank test or McNemar's test. RESULTS: The mean age was 42.7 years and 20 (47%) patients had associated urgency UI (UUI), whilst 21 (49%) had intrinsic sphincter deficiency. The median (range) operative duration was 14 (5-35) min. There were no complications during surgery. The mean (SD, range) follow-up was 28.1 (5.1, 18-36) months. Postoperative complications were vaginal discharge (5%), failure of wound healing (5%), dyspareunia (5%) and UTI (5%). The sling was removed in one case. SUI, UUI and quality-of-life indices improved significantly after surgery. There were no significant differences in pressure-flow studies before and after surgery. In all, 38 (88%) patients were cured, four (9%) improved and in one only the treatment failed (2%). CONCLUSION: This technique is simple, safe, effective, reproducible and economical for treating SUI. The STM was easy to insert in a short operation.

ABSTRACT

PURPOSE: To assess the impact of multiple access tracts during percutaneous nephrolithotomy (PCNL) on short- and midterm renal function, and to determine risk factors predicting renal function deterioration and/or recoverability. PATIENTS AND METHODS: Patients undergoing PCNL with multiple punctures were prospectively enrolled. Preoperative evaluation included dimercaptosuccinic acid and diethylenetriaminepentaacetic acid renography. Patients were classified according to baseline renal function into patients with normal (<1.4 mg/dL) serum creatinine (group A) and patients with elevated (≥1.4 mg/dL) serum creatinine (group B). Patients were followed with serial serum creatinine evaluations and a repeated renography at 12 months. Factors evaluated for possible impact on renal function changes included preoperative renal function, number of access tracts, hypertension, and diabetes mellitus. RESULTS: There were 102 patients 21 to 65 (mean 39.9) years who completed the study. Fifty patients (group A) had normal preoperative serum creatinine levels and glomerular filtration rate (GFR), which showed no statistically significant change 12 months after PCNL. Fifty-two patients had baseline renal impairment (group B), and they experienced statistically significant worsening of the serum creatinine level and GFR at 12 months postoperatively (P<0.001). Ten (19.23%) patients in group B had a significant deterioration of GFR more than 25%. Independent risk factors for this poor outcome were elevated (≥1.4 mg/dL) preoperative serum creatinine level, diabetes, and hypertension. CONCLUSION: PCNL with multiple tracts carries a risk of adversely affecting renal function. Preoperative baseline renal impairment, diabetes, and hypertension are risk factors for significant renal function deterioration after the procedure.
