Follow-Up of Testicular Microlithiasis for Subsequent Testicular Cancer Development

Introduction: To demonstrate the relationship between testicular microlithiasis and testicular tumor development. Patients and Methods: Between January 1996 and March 2004, bilateral testicular microlithiasis was found in 40 of the 5,263 patients who underwent scrotal ultrasonography yielding a prevalence of 0.76%. Of the 40 patients, 4 patients with concomitant testicular tumors were excluded from the study. The remaining 36 patients were enrolled into the study and followed by ultrasonography at 6-month intervals. Results: Patient ages ranged between 1 and 69 years (mean 31 ± 14 years). The median ultrasonography follow-up was 34 months (range, 1–96). Testicular tumor development was not observed in any of these 36 patients during the follow-up period. Conclusions: Extensive evaluation including computerized tomography, testicular tumor markers and testicular biopsyof patients with testicular microlithiasis is unnecessary and also increases patient anxiety. Yet annual ultrasonography and physical examination should be performed if ever until testicular microlithiasis is completely accepted as a nonpremalignant disease.

Emphysematous pyelonephritis and renal amoebiasis in a patient with diabetes mellitus

Emphysematous pyelonephritis is an uncommon and life‐threatening infection of the kidney that is characterized by gas formation within or around the kidney and is associated with diabetes mellitus and urinary tract infection. Amoebiasis is a protozoal infection caused by Entamoeba histolytica. In its invasive forms, the disease is characterized by visceral abscess formations. We present a case of concomitant emphysematous pyelonephritis and renal amoebiasis in a 42‐year‐old female with uncontrolled diabetes mellitus. The patient did not respond well to initial supportive treatment and antibiotherapy. Therefore, nephrectomy was performed. She did extremely well after the operation and was discharged with antidiabetics and antibiotics.

Primary Renal Lymphoma: Report of Four Cases

Background: Although secondary renal involvement from systemic lymphoma is very frequent, primary renal lymphoma is a rare entity. It is characterized by aggressive histopathology, very early extra-renal infiltration and poor prognosis. Case Reports: Here, we report 4 cases of primary renal lymphoma presenting with unilateral renal masses, which after radiological and clinical examination were assumed to be renal cell carcinoma. 3 patients were diagnosed with Non-Hodgkin’s lymphoma by nephrectomy and one patient was diagnosed by open renal biopsy. Histopathological subtypes were diffuse large B cell lymphoma in 2 cases and non-Hodgkin’s lymphoma of small B cell type in the others. While 3 of the patients were treated with systemic chemotherapy, the fourth patient refused chemotherapy. 2 patients (no. 2 and 3) were still in complete remission and were followed regularly in the second and first year after diagnosis, respectively. Conclusions: Since it is difficult to diagnose primary renal lymphoma, most patients with this kind of tumor undergo radical nephrectomy, and diagnosis of primary renal lymphoma is delayed. The authors believe that both the delayed diagnosis due to anatomical difficulties and the histological aggressive characteristics of this disease are equally responsible for the poor outcome in the case of primary renal lymphoma.

Effects of Selective Alpha-1-Adrenergic Receptor Blockers on Bladder Weight

Introduction: This study was undertaken to investigate the effects of two different α1-adrenergic blockers on bladder hypertrophy using ultrasound-estimated bladder weight (UEBW) and to assess the relation between changes in UEBW and other objective and subjective parameters of disease severity in patients with benign prostatic hyperplasia (BPH). Materials and Methods: 41 men were enrolled in the study and they were subjected to either watchful waiting (group 1) or α1-adrenergic receptor blocker therapy (group 2 with alfuzosin; group 3 with tamsulosin). The patients were investigated by symptom evaluation using the International Prostate Symptom Score (IPSS) and quality of life score (QOL), uroflowmetry and UEBW. The parameters were assessed again 3 months after initiation of treatment and compared with the initial values. Results: While the mean UEBW increased in group 1 (42.2 ± 10.3 to 52.5 ± 12.2 g), it decreased in both the other groups that received α-blocker therapy (61.3 ± 18.7 to 41.1 ± 13.2 and 59.4 ± 17.2 to 43.5 ± 17.6 g, respectively). In groups 2 and 3, the mean UEBW, post-void residual urine, IPSS and QOL values decreased, and the mean maximum flow rate increased. All of the changes in group 2 and all except QOL in group 3 were statistically significant (p < 0.05). The changes correlated well with each other with regard to treatment success. The highest decreases in UEBW were encountered in patients with heavier bladders. Conclusions: UEBW decreases with α1-adrenergic receptor blockers. When used together with the other objective and subjective parameters, UEBW is a promising quantitative parameter as a follow-up tool and can be useful in monitoring the therapeutic effects of α1-adrenergic receptor blockers.

Does Ischemia-Induced Prostate Damage during Cardiac Surgery Involving Cardiopulmonary Bypass Cause Bladder Outlet Obstruction?

Objective: This study sought to investigate whether ischemia-induced prostate damage during cardiac surgery involving cardiopulmonary bypass causes bladder outlet obstruction. Materials and Methods: The study involved 37 men who underwent elective cardiac surgery involving cardiopulmonary bypass. Prostate-specific antigen (PSA) levels were determined preoperatively (baseline) and on postoperative days 1, 5, and 30. In 4 cases, the PSA level after the operation was unchanged from the preoperative level, so these 4 men were excluded from the study. In the remaining 33 patients, symptoms of bladder outlet obstruction were assessed using the International Prostate Symptom Score. Each subject completed this test preoperatively and 3, 6 and 9 months postoperatively, and the means scores at these time points were compared. The effects of patient age, operative time, CPB time, and aortic clamping time on postoperative increases in PSA levels were investigated. Results: Thirty-three (89.2%) of the 37 men exhibited increased postoperative PSA levels compared to baseline. The mean PSA level for the 33 cases on day 5 was significantly higher than the baseline mean, but the mean levels on postoperative days 1 and 30 were comparable to baseline. Nine (24.3%) of the 33 men had postoperative PSA levels greater than 4.0 ng/dl (the upper normal limit). There was no significant difference between preoperative and postoperative International Prostate Symptom Scores. Conclusion: The study indicates that men’s PSA levels are, indeed, increased after cardiac surgery with cardiopulmonary bypass. However, in 9 months of follow-up, there was no association between this PSA rise and development of BOO, according to International Prostate Symptom Scores.

Intratesticular varicocele: Report of two cases

Intratesticular varicocele is a rare entity and describes dilated intratesticular veins radiating from the mediastinum testis into the testicular parenchyma. Scrotal ultrasonography of two patients who presented to our urology clinic due to left scrotal pain revealed multiple tubular structures in the testes with diameters of more than 2 mm. Duplex spectral analysis showed a reversed flow response to Valsalvas maneuver. Apropos of two cases, intratesticular varicocele is reviewed.

Sarcomatoid Carcinoma of the Urinary Bladder Treated with Adjuvant Radiotherapy: A Case Report

Sarcomatoid carcinoma is a rare tumor of the urinary bladder accounting for less than 0.5% of all primary urinary bladder tumors. Since the patients were presented with large tumor with extended stages, outcome was found to be poor. In order to improve local control, adjuvant local treatment may be practical. We report a rare case with sarcomatoid carcinoma of the urinary bladder diagnosed with immunuhistochemical (IHC) study and treated with 3D-conformal radiotherapy (3DCRT) post-operatively. A 55-year old female patient complained about painless hematuria for 2 months. Computed tomography of the pelvic region revealed tumor and wall thickening at the left posterolateral side of the bladder. Total cystectomy with lymph node dissection and total abdominal hysterectomy and bilateral salphingo-oopherectomy was performed and histopathological and immunohistochemical findings strongly correlate with sarcomatoid carcinoma. The patient was treated with 3D conformal radiotherapy (3DCRT) with a total dose of 59.4 Gy with 1.8 Gy fractional daily doses. Patient was alive without any local recurrence and distant metastasis 10 months after surgery.
