During a twelve-month period, 416 children with acute abdominal pain required emergency admission to Southampton General Hospital; 46% had operations. Appendicitis was the commonest organic cause of acute abdominal pain identified (31%). Constipation (9%) can present as acute abdominal pain simulating appendicitis. All children should have a urine sample examined microscopically and the finding of significant pyuria is suggestive, but not diagnostic, of a urinary tract infection (7%). Mesenteric adenitis, which can only be diagnosed with certainty at laparotomy, was less common (4%). Despite careful clinical assessment and follow up, 45% of children in this series remained undiagnosed. Sedation but not analgesia may assist in the diagnosis of the acute abdomen in children.

Presentation of two clinical cases of spontaneous vesical rupture secondary to bacterial cystitis in elderly patients. One corresponds to an intraperitoneal perforation while the second case was extraperitoneal. The patients were, in both cases, diabetic women admitted in emergency due to acute abdomen. We considered that although vesical perforation secondary to bacterial cystitis is a very uncommon process, it should be taken into account in the differential diagnosis of acute abdomen in predisposed patients (diabetic elderly patients with pyuria). In such instances, a retrograde cystography would provide the diagnosis. Although extraperitoneal vesical perforations can be resolved with a vesical catheter or cystostomy, extravasation of the infected urine may result in a perivesical abscess and septic shock. Early surgical management should be considered in these cases.

Managing acute abdomen is a challenge for physicians in the emergency department. An immediate surgery is sometimes required for the hemorrhagic uropathy of renal angiomyolipoma. We present a case with left flank pain and findings of hematuria and pyuria. Abdominal and pelvic computed tomographic scans showed a 3 x 5-cm, fat-containing tumor at the left lower pole of the kidney and a bleeding and perirenal hematoma in the left perirenal space. An urgent left nephrectomy was lifesaving for the postoperative finding of renal angiomyolipoma. It is important to consider the possibility of the presence of such a tumor when spontaneous retroperitoneal hemorrhage and hypovolemic shock are encountered.
