  ABSTRACT: The aim of this study was to find out on an unselected patient group whether crossing vessels have an influence on the width of the renal pelvis and what independent predictors of these target variables exist. In this cross-sectional study, 1072 patients with arterially contrasted CT scans were included. The 2132 kidneys were supplied by 2736 arteries. On the right side, there were 293 additional and accessory arteries in 286 patients, and on the left side there were 304 in 271 patients. 154 renal pelves were more than 15 mm wide. The greatest independent factor for hydronephrosis on one side was hydronephrosis on the contralateral side (p<0.0001 each). Independent predictors for the width of the renal pelvis on the right side were the width of the renal pelvis on the left, female gender, increasing age and height; for the left side, predictors were the width of the renal pelvis on the right, concrements, parapelvic cysts and great rotation of the upper pole of the kidney to dorsal. Crossing vessels had no influence on the development of hydronephrosis. Only anterior crossing vessels on the right side are associated with widening of the renal pelvis by 1 mm, without making it possible to identify the vessel as an independent factor in multivariate regression models. The width of the renal pelvis on the contralateral side is the strongest independent predictor for hydronephrosis and the width of the renal pelvis. There is no link between crossing vessels and the width of the renal pelvis.

• Article: [Functional retrourethral sling. A change of paradigm in the treatment of stress incontinence after radical prostatectomy].

  ABSTRACT: The ever rising number of radical prostatectomies entails an increasing number of patients suffering from postoperative stress incontinence. Several minimally invasive techniques exist as surgical intervention options. All these procedures are based on an obstruction of the urethra. The functional retrourethral sling is a new and innovative sling suspension, which offers for the first time a non-obstructive functional therapeutic approach. The sling adjusts the changed anatomy after radical prostatectomy and exerts its effect by repositioning the lax and descended supporting structures of the sphincter in the former preoperative position. Thus continence can be achieved again. The success rate of this new technique is very good, yielding good results regarding both improving incontinence and continence rate. This new technique is secure and the results are reproducible.

  ABSTRACT: Objective: The incidence of urethral injuries in children is rare due to the fact that the urethra is short, mobile and protected by the pubic bone. The management of urethral trauma in childhood remains controversial because of the limited expertise of most urologists. Material and Methods: We performed a literature review by searching the Medline database for articles published between 1975 and 2010 based on clinical relevance. Electronic searches were limited to the keywords 'pediatric', 'urethral injury', 'trauma' and 'reconstruction'. Results: Retrograde urethrography is considered the gold standard for diagnosis of urethral injuries. The initial management should ensure drainage of the bladder either by suprapubic cystostomy or urethral realignment if possible: in complete anterior urethral disruption as well as in children with life-threatening pelvic and intra-abdominal injuries after posterior urethral injuries, a deferred repair after 3 months is necessary. Immediate primary suturing of disrupted and dislocated urethral ends should be avoided because of high complication rates. Primary repair, however, of the defect is possible in girls avoiding a 2-stage approach. Conclusion: The aim of therapy is minimizing remote damages such as urethrocutaneous fistulae, periurethral diverticulae, strictures, incontinence and impotence with different therapeutic management depending on classification of the injury and the presence of life-threatening injuries.

  ABSTRACT: We evaluated whether unilateral low-dose spinal anesthesia may reduce the likelihood of postoperative urinary retention. Forty patients scheduled for knee arthroscopy randomly received bilateral (n = 20) or unilateral (n = 20) spinal anesthesia with 6-mg hyperbaric bupivacaine 0.5%. The incidence of urinary retention (>500 mL) assessed with an ultrasound device (Bladderscan) and subsequent temporary catherization was 7/20 patients in the bilateral versus 6/20 in the unilateral group (not significant). We concluded that unilateral low-dose spinal anesthesia does not further decrease the likelihood of urinary retention. Our results demonstrate the value and necessity of monitoring bladder volume postoperatively.
