Outcomes of outpatient ureteral stenting without fluoroscopy at Groote Schuur Hospital, Cape Town, South Africa.

BACKGROUND: Ureteral stenting is generally a theatre-based procedure that requires a multidisciplinary team and on-table imaging. Limited hospital bed numbers and theatre time in our centre in Cape Town, South Africa, have led us to explore an alternative approach. OBJECTIVES: To see whether outpatient insertion of ureteric stents under local anaesthesia without fluoroscopy was a possible and acceptable alternative to theatre-based ureteral stenting. METHODS: Ureteral stenting (double-J stents and ureteric catheters) was performed with flexible cystoscopy under local anaesthesia and chemoprophylaxis, but without fluoroscopic guidance, in an outpatient setting. Every patient had an abdominal radiograph and an ultrasound scan of the kidney after the procedure to confirm stent position. RESULTS: Three hundred and sixteen procedures (276 double-J stents and 40 ureteric catheters) were performed in 161 men and 155 women. The overall success rate for the procedures was 85.4%, independent of gender (p=0.87), age (p=0.13), type of device inserted (p=0.81) or unilateral/bilateral nature of the procedure (p=1.0). Procedures with a successful outcome were performed in a significantly (p<0.0001) shorter median time (10 minutes (interquartile range (IQR) 5 - 15)) than failed procedures (20 minutes (IQR 10 - 30)). Patients with a pain score of >5 experienced a significantly (p=0.02) greater proportion of failure (27.3%) than patients with a pain score of ≤5 (12.5%). Difficulties were encountered in 23.7% of procedures, with a significantly higher proportion being registered in failed interventions compared with successful ones (82.6% v. 13.7%; p<0.0001). CONCLUSIONS: The procedure was easily mastered and technically simple, and represents savings in cost, time and human resources in our setting.

Nonoperative management of penetrating kidney injuries: a prospective audit.

PURPOSE: The role of nonoperative management for penetrating kidney injuries is unknown. Therefore, we review the management and outcome of penetrating kidney injuries at a center with a high incidence of penetrating trauma. MATERIALS AND METHODS: Data from all patients presenting with hematuria and/or kidney injury discovered on imaging or at surgery admitted to the trauma center at Groote Schuur Hospital in Cape Town, South Africa during a 19-month period (January 2007 to July 2008) were prospectively collected and reviewed. These data were analyzed for demographics, injury mechanism, perioperative management, nephrectomy rate and nonoperative success. Patients presenting with hematuria and with an acute abdomen underwent a single shot excretory urogram. Those presenting with hematuria without an indication for laparotomy underwent computerized tomography with contrast material. RESULTS: A total of 92 patients presented with hematuria following penetrating abdominal trauma. There were 75 (80.4%) proven renal injuries. Of the patients 84 were men and the median age was 26 years (range 14 to 51). There were 50 stab wounds and 42 gunshot renal injuries. Imaging modalities included computerized tomography in 60 cases and single shot excretory urography in 18. There were 9 patients brought directly to the operating room without further imaging. A total of 47 patients with 49 proven renal injuries were treated nonoperatively. In this group 4 patients presented with delayed hematuria, of whom 1 had a normal angiogram and 3 underwent successful angioembolization of arteriovenous fistula (2) and false aneurysm (1). All nonoperatively managed renal injuries were successfully treated without surgery. There were 18 nephrectomies performed for uncontrollable bleeding (11), hilar injuries (2) and shattered kidney (3). Post-nephrectomy complications included 1 infected renal bed hematoma requiring percutaneous drainage. Of the injuries found at laparotomy 12 were not explored, 2 were drained and 5 were treated with renorrhaphy. CONCLUSIONS: Penetrating trauma is associated with a high nephrectomy rate (24.3%). However, a high nonoperative success rate (100%) is achievable with minimal morbidity (9%).

Potential victim's role in the prevention of rape.

The 'It can't happen to me' attitude of women towards rape results in their ignorance concerning the action to take when confronted by a rapist. They can either resist, hoping to repel the rapist, or they can obey his commands, hoping he will depart without maiming or killing them. The view is put forward that a woman's best strategy is to resist. Intimidation is the rapist's best weapon, a necessary procondition to rape. The potential victim should refuse to be intimidated. Rapists are on the lookout for women who are vulnerable to attack. The perception of vulnerability differs from one rapist to another. Rapists test, then threaten. Testing is crucial for the rapist, for if he guesses wrongly about whether a woman can be intimidated he will lose his opportunity to rape her. Most rapists are not murderers. It is important that the potential victim should resist at the beginning of the attack and should not look vulnerable on the street. The potential victim should be advised to know her own strength, to be prudent, prepared and to have the necessary knowledge that will enable her to protect herself.
