Spontaneous rupture of ileal neobladder: a case report.

A 63-year-old male patient suffered from diabetes, hypertension, and a bladder tumor. He had undergone radical cystectomy and ileal neobladder construction 1 year prior to this admission. He came to our emergency room complaining of abdominal pain after recent alcohol consumption. Muscle guarding and abdominal rebounding pain developed after conservative treatment for 1 day. The next day, emergency laparotomy for acute peritonitis revealed two small perforations in the neobladder and calculus formation within it. In addition, severe intraperitoneal adhesion was noted. After removing the neobladder stone and repairing the neobladder, a Foley catheter was inserted for urine drainage. The patient's postoperative recovery was excellent.

Relationships between American Urological Association symptom index, prostate volume, and disease-specific quality of life question in patients with benign prostatic hyperplasia.

The American Urological Association (AUA) symptom index is both valid and reliable in identifying the need to treat patients with benign prostatic hyperplasia (BPH) and in monitoring their response to therapy. We evaluated the relationships between AUA symptom index, disease-specific quality of life question, and prostate volume in patients with BPH. A total of 100 patients who came to Kaohsiung Medical University Hospital, Taiwan, for help due to lower urinary tract symptoms (LUTS) and who were diagnosed with BPH between October 2002 and June 2003 were included in the study. All patients were evaluated using transrectal ultrasonography, AUA symptom index, and disease-specific quality of life question. The disease-specific quality of life question showed good correlation with AUA symptom score (r = 0.815, p < 0.01), but weak correlation with prostate volume (r = 0.225, p < 0.05) and age (r = 0.274, p < 0.05). Prostate volume had weak correlation with AUA symptom score (r = 0.251, p < 0.05) and age (r = 0.472, p < 0.01), but good correlation with prostate specific antigen (r = 0.638, p < 0.01). In addition to AUA symptom index, we suggest using the disease-specific quality of life question to evaluate the influence on quality of life and response to treatment in clinical practice. Moreover, we should assess the impact of BPH symptoms rather than the increase in prostate volume during the management of BPH.

Current indications for transurethral resection of the prostate and associated complications.

Transurethral resection of the prostate (TURP) is the most common surgical procedure for relieving symptoms of benign prostatic hyperplasia. Here, we report our experience of current indications for TURP and their associated outcomes at Kaohsiung Medical University Hospital (KMUH). A total of 111 patients who underwent TURP at KMUH between May 2000 and December 2001 were included in this retrospective review. For each patient, the surgical indication was categorized into acute urinary retention, chronic complications (including renal impairment, recurrent urinary infection, bladder stone/diverticulum, post-void residue, and recurrent hematuria), and symptomatic prostatism. Thirty-five patients (31%) had acute urinary retention, 28 (27%) had chronic complications, and 48 (42%) had symptomatic prostatism. Most patients chose TURP only when medical treatment had failed to relieve symptoms, no matter what category they belonged to. Patients with acute urinary retention and chronic complications had larger prostates (p = 0.002) and more tissue resected (p = 0.05) than those with symptomatic prostatism. Patients with acute urinary retention seemed to be at greater risk of postoperative complications such as recurrent urinary retention and urinary tract infection. We suggest that urodynamic study may be necessary to rule out concomitant bladder dysfunction before surgery and that adequate prophylactic antibiotic treatment be used to decrease the risk of urinary tract infection during or after TURP, especially when pyuria is noted preoperatively in patients with acute urinary retention.

Giant extrarenal retroperitoneal angiomyolipoma: a case report and literature review.

Extrarenal angiomyolipoma is an uncommon disease entity and is rare in the retroperitoneum. We report a case of giant extrarenal retroperitoneal angiomyolipoma mimicking liposarcoma. A 35-year-old woman presented with a history of increased abdominal circumference and urinary frequency. Abdominal computerized tomography demonstrated a 24 x 21 x 16 cm retroperitoneal fatty tumor displacing the right kidney to the left upper quadrant of the abdomen. At laparotomy, the tumor was widely excised and the right kidney was successfully preserved. Final histologic examination identified the tumor as an angiomyolipoma. At 4-month postoperative follow-up, no evidence of tumor recurrence was found and the right kidney was fully functional.

Spontaneous renal hemorrhage associated with idiopathic thrombocytopenic purpura--a case report.

Spontaneous renal hemorrhage is a rare and complicated clinical condition. We report a case of spontaneous renal hemorrhage associated with idiopathic thrombocytopenic purpura (ITP). To our knowledge, this is a second case associated with ITP in the literature. The main treatment of our case included absolute bed rest, platelet transfusion, steroid therapy and prevention of infection. The platelet count increased gradually and returned to the safe level greater than 50,000/microliter from the 10th day. The patient was discharged after 2 weeks due to stable condition and received further follow-up in the outpatient department. We suggest that conservative treatment for spontaneous renal hemorrhage caused by blood dyscrasias like ITP is appropriate because immediate surgical intervention may pose a higher risk due to the tendency for severe bleeding. However, long term follow-up by serial CT should be performed to rule out the possibility of concomitant diseases especially small renal cell carcinoma, which is the most common cause of spontaneous renal hemorrhage.

Matrix stone.

Matrix stone is a rare form of renal calculi, and it is often difficult to make an exact preoperative diagnosis. To our knowledge, we reported the first case of matrix stones which received magnetic resonance imaging (MRI) for image study. They showed hypointense signal in T1-weighted images and slight hyperintense signal in T2-weighted images. No obvious contrast enhancement was found after gadolinium administration in T1-weighted images. Besides, postoperative study of computerized tomography (CT) for matrix stones also showed the characteristic of soft tissue densities by measuring the Hounsfield units. We think our experiences may provide some help for the diagnosis of matrix stones when someone encounters the same situation and may prevent overtreatment due to misdiagnosis as malignancy.
