Eosinophilic cystitis mimicking hemorrhagic cystitis in relapsed follicular lymphoma.

Eosinophilic cystitis (EC) is a rare and non-infectious inflammatory disorder characterized by transmural infiltration of eosinophils in the bladder wall. The diagnosis of EC is made only by the pathophysiological findings. Because the urinary symptoms of EC are quite similar to other urinary tract disorders including hemorrhagic cystitis (HC), it can be misdiagnosed or left undiagnosed. A 49-year-old woman with relapsed and refractory follicular lymphoma presented with sudden-onset gross hematuria after the chemo-immunotherapy. The patient was initially treated as HC with continuous bladder irrigation, resulting in recurrent and refractory hematuria. Corticosteroid dramatically resolved hematuria after the bladder biopsy revealed EC. It is important to suspect EC and perform bladder biopsy in patients with recurrent episodes of hematuria or refractory to conservative treatment for HC.

Eosinophilic funiculitis initially diagnosed as irreducible inguinal hernia: A case report.

BACKGROUND: Most groin masses are first suspected to be groin hernias. More than 80% of bulging groin lesions are reportedly diagnosed as hernias by ultrasonography. Establishment of the correct diagnosis of hernia among all differential diagnoses is not easy. We herein describe a very rare case of groin eosinophilic funiculitis that presented as an irreducible groin hernia. CASE PRESENTATION: A 59-year-old man presented to our hospital with suspicion of a right groin hernia. He had a 1-week history of a painful right groin tumor. The tumor was about 4 cm without skin redness or warmth, irreducible even in the supine position, and associated with mild tenderness. Enhanced computed tomography showed that the mass seemed to be connected to the intra-abdominal structures. With time, the patient's pain did not increase, the inflammatory response did not worsen, and no ischemic signs were observed by enhanced computed tomography. Therefore, we diagnosed the tumor as an irreducible but not incarcerated hernia and performed elective surgery. Intraoperative examination revealed no hernia sac, and a 4-×3-cm tumor was observed around the spermatic cord. A malignant tumor was not completely ruled out. High orchiectomy was performed after consultation with the urologists. Pathological examination of the tumor showed no malignant features, and the final diagnosis was eosinophilic funiculitis with massive inflammatory changes and eosinophil invasion. CONCLUSION: Eosinophilic funiculitis is very rare; only three cases have been reported to date. We should always consider unusual causes of groin masses during a surgical approach to hernia-like lesions.

Annual PSA tests are not necessary for men with a PSA level below 2 ng/mL: findings of the Imari prostate cancer screening program.

BACKGROUND: Annual changes in prostate specific antigen (PSA) levels detected by the Imari prostate cancer screening program were evaluated to establish a more efficient and cost-saving screening system, especially for men with low PSA levels. METHODS: Prostate specific antigen-based annual mass screenings for prostate cancer were conducted for men aged 60-69 in the Imari district, Saga, Japan. Between 1992 and 2000, 1822 men had their PSA levels tested. A total of 4661 PSA tests were conducted. Changes in PSA levels over the following 1 to 5 years were analyzed in men with PSA levels of 3 ng/mL or less, a range in which the detection rate of prostate cancer would seem to be negligibly low. RESULTS: The overall detection rate of prostate cancer between 1992 and 2000 was 0.73%. The detection rate in men with a PSA level between 3.1 and 3.9 ng/mL, and between 4 and 9.9 ng/mL was 1.6% and 8.3%, respectively. Of 4661 determinations of PSA, 2553 (54.8%) were found to be < or = 1 ng/mL, 1273 (27.3%) were between 1.1 and 2 ng/mL, and 401 (8.6%) were between 2.1 and 3 ng/mL. Four hundred and thirty-four men (9.3%) had PSA levels > or = 3.1 ng/mL, with possible indications for prostate biopsy. Of the men tested, 1.4% with an initial PSA level of < or = 2 ng/mL and 22.3% with an initial level between 2.1 and 3 ng/mL had a PSA level of > or = 3.1 ng/mL after 1 year. Almost the same rate of PSA increase was observed between the two PSA tests conducted at 2 to 5-year intervals. Of the men tested, 2.2% with an initial PSA level of < or = 2 ng/mL, and 21.9% with an initial level between 2.1 and 3 ng/mL, had a level of > or = 3.1 ng/mL after 5 years. CONCLUSION: Levels of PSA in men with an initial level below 2 ng/mL remained stable for up to 5 years. Levels of PSA in 97.8- 98.8% of men remained below 3 ng/mL after 1 to 5 years. In contrast, 18-35.3% of men with an initial PSA level between 2.1 and 3 ng/mL showed PSA progression to 3.1 ng/mL or more within 5 years. Our present data suggest that annual PSA testing is not necessary for men with a PSA level below 2 ng/mL. Prostate specific antigen testing could therefore be conducted at longer intervals in such individuals.

Hand-assisted retroperitoneoscopic nephroureterectomy for upper urinary-tract urothelial tumors.

PURPOSE: We report our experience with hand-assisted retroperitoneoscopic nephroureterectomy for upper urinary-tract urothelial cancer. PATIENTS AND METHODS: Our initial 10 cases of clinical stage T(1)N(0)M(0) renal pelvic and ureteral tumors treated with hand-assisted retroperitoneoscopic nephroureterectomy are included in the present report. Nephrectomy was conducted retroperitoneoscopically with hand assistance via a lower-abdominal midline incision. Resection of the lower ureter together with the bladder cuff was performed as open surgery and the specimen was removed en bloc via the same incision. RESULTS: Hand-assisted retroperitoneoscopic nephroureterectomy was completed successfully in all 10 cases. The mean operating time was 456 +/- 90 minutes, and the mean estimated blood loss was 462 +/- 364 mL. The times to oral intake and walking were 1.5 +/- 0.5 days and 2.3 +/- 0.7 days, respectively. One case of renal vein injury, one case of pulmonary embolism, and three cases of wound infection were the complications. CONCLUSION: This is the first report of hand-assisted endoscopic nephroureterectomy using the retroperitoneal approach. The surgical technique seems quite reasonable because the lower-abdominal incision can be utilized, not only as a route for hand assistance, but also as a window for open surgery when resecting the distal ureter as well as for extracting the surgical specimen.
