Ureteroscopy Outcome and Its Determinants in a Resource-Limited Setting.

Background: Ureteroscopy is a major diagnostic and therapeutic technique for lesions of the ureter and intrarenal collecting system. Methods: A retrospective chart review was done at St. Paul's Hospital Millennium Medical College, Ethiopia to determine the outcome of ureteroscopy and factors affecting it. The study period was from January 2018 to April 2018. Multivariate analysis was done to determine factors affecting stone clearance and success rate. Result: One hundred six patients who underwent semirigid ureteroscopy were included in the study. The male-to-female ratio was 1.8:1. The mean age of the patients was 36.4 years (±12.6). Ninety-six (90.6%) patients were found to have ureteric stones, while 9(8.5%) patients had a ureteric stricture. Ureteroscopy therapeutic interventions for stones were successful in 89 (92.7%) patients. The mean procedure time and postoperative hospital stay were 44 minutes (±23.7) and 2.5 days (±2.5) respectively. Intraoperative complications (ureteric avulsion, hemorrhage, and ureteral perforations) occurred in 6(5.7%) patients. The stone clearance rate was 54.7% (52). The site of obstruction was passed in 93 patients making the success rate of the procedure 87.7%. The absence of intraoperative complications was significantly associated with success rate. Patients with intraoperative complications have low success rate (20%) compared to patients without complications (92.3%), p=0.42. Conclusions: Semirigid ureteroscopy had a good success rate, especially for stones in the distal ureter and if there is no flexible ureteroscope, it is an acceptable alternative.

Appendiculo-ileal knot presenting at the third trimester of pregnancy.

Though appendicitis is the most common cause of acute abdomen, the vermiform appendix as a cause of small bowel obstruction is a rarity. The inflamed appendix can cause obstruction by making a knot around the small bowel. There are only few case reports on Appendico-ileal knotting (AIK). We have not found any report on AIK causing small bowel obstruction during pregnancy. The diagnosis of acute abdomen in pregnancy is difficult due to the accompanying anatomic and physiologic changes. Because obstruction due to AIK present like any other cause of obstruction diagnosing the condition pre-operatively is uncommon. Here, we report 30 years old Gravida 9, Para 8 women who presented with cardinal symptoms of small bowel obstruction at term and found to have AIK intra-operatively. The challenge of difficulty in making the diagnosis and management options are discussed.
