Is ureteroscopy first line treatment for pediatric stone disease?

PURPOSE: We report our current outcomes for ureteroscopic management of pediatric stone disease. MATERIALS AND METHODS: We carried out a retrospective review of all ureteroscopic procedures for kidney or ureteral calculi performed between 2001 and 2005. Stone location and size, preoperative and postoperative stenting, intraoperative dilation, use of ureteral access sheath, stone-free rates and complications were noted. RESULTS: A total of 100 patients (58% female, mean age 13.2 years) underwent 115 procedures. Stones were located in the renal pelvis in 6% of patients, upper pole in 10%, mid ureter in 11%, lower pole in 17%, proximal ureter in 19% and distal ureter in 37%. Mean stone size was 8.3 mm (median 7.0), with a mean of 1.5 stones per patient. Preoperative stenting was used in 54% of patients, and a stent was placed postoperatively in 76%. Ureteral coaxial dilators and ureteral access sheaths were used in 70% and 24% of patients, respectively. There were no major intraoperative complications, although 5 patients required stent placement for ureteral perforation or extravasation. One patient had a ureteral stricture requiring ureteral reimplantation. Mean followup was 10.1 months (median 2.6). Stone-free rate was 91% on followup ultrasound, abdominal radiography or computerized tomography. Seven patients required staged ureteroscopic procedures to achieve stone-free status. While the number of percutaneous nephrolithotomy and shock wave lithotripsy cases remained stable, the number of ureteroscopic cases increased 7-fold during this period. CONCLUSIONS: Improved ureteroscopic access to stones throughout the pediatric urinary tract and stone-free rates that are comparable to the adult population have led to the adoption of ureteroscopy as first line therapy in children at our institution.     

Is this patient penicillin-allergic?

Increased claims of hypersensitivity reactions are being reported due to the inability to differentiate between the terms "allergic reaction" and "adverse effect."     

Is mastectomy overtreatment for Paget's disease of the nipple?

The standard local management for Paget's disease of the nipple is currently mastectomy although this may well represent overtreatment. The place of breast conserving surgery is somewhat uncertain. We have reviewed the casenotes of 146 patients with Paget's disease of the nipple, and compared the mortality and recurrence rates between 74 women who had undergone mastectomy and 31 women who had breast conserving surgery. There was no significant difference in either local or overall treatment failure rates between these two treatment groups. We conclude that breast conserving treatment maybe an appropriate alternative to mastectomy for the management of Paget's disease, where clear margins of excision can be achieved. However, a randomized prospective study is needed to confirm this.     

Is thoracoscopic decortication sufficient for the treatment of empyema?

Before thoracoscopy became popular in the 1990s, thoracotomy and decortication was the treatment of choice for empyema thoracis not responding to tube thoracostomy. An Institutional Review Board-approved, retrospective review of all patients treated for empyema between September 1, 2006, and August 31, 2009, at Kern Medical Center was conducted. A total of 37 patients (male=33; female=4) with a mean age of 43.7 years were treated. Empyema developed after community-acquired pneumonia (CAP) in 27, traumatic hemothorax (TH) in nine, and other cause in one. For 34 of 36 patients (91%), a thoracoscopic approach was successful. Two of 36 patients required conversion to thoracotomy, whereas one patient required an initial thoracotomy in each case as a result of tenacious adhesions. Mean duration of the chest tube was 4.1 days in patients with CAP and 4.6 days in patients with TH. Mean length of stay after surgery was 6 days for patients with CAP and 9.1 days for patients with TH. Five of 37(13.5%) had complications and one patient died (2.7%). Follow-up was complete for 81.1 per cent of patients, none of whom required a subsequent intervention. Compared with the literature, it appears that the conversion rate to thoracotomy, length of chest tube duration, and postoperative length of stay have decreased as experience has increased.
