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.

Long-Term Renal Function and Stone Recurrence After Percutaneous Nephrolithotomy in Patients with Renal Insufficiency

PURPOSE We analyzed long-term results after percutaneous nephrolithotomy (PCNL) in patients with impaired renal function. PATIENTS AND METHODS Nineteen (6.3%) of 300 patients who underwent PCNL had serum creatinine values above 1.4 mg/dL before surgery and were considered to have impaired renal function. Success rate of operation, recurrence rate, and renal functional status were evaluated. RESULTS Mean follow-up time was 51.1 +/- 10.1 months. Sixteen patients completed the study, but three patients were lost to follow-up. The results of the operation were as follows: stone free in 50%, clinically insignificant residual fragments in 25%, and clinically significant residual fragments in 25% of the patients. Mean serum creatinine value was 2.30 +/- 0.56 mg/dL before surgery and 2.67 +/- 1.41 mg/dL at the end of follow-up (p = 0.386). Creatinine values decreased to normal range in six patients (37.5%). Six patients (37.5%) had stable renal function (creatinine: 1.4-4 mg/dL). Creatinine values increased (>4 mg/dL) in four patients (25%) who required renal replacement therapy. Three new patients progressed to end-stage renal failure. These three had insulin-dependent type II diabetes mellitus and one also had solitary kidney and atherosclerosis. Two patients (12.5%) had recurrences, one of these had hypercalciuria, and the other had infection stone. CONCLUSION Our results indicated that most patients presenting with kidney-stone disease and renal insufficiency experience improvement or stabilization of renal function after PCNL. The patients with solitary kidney and those with conditions such as diabetes and atherosclerosis might be at greater risk for deterioration of renal function. Patients with metabolic abnormalities and infection stones might be at higher risk for recurrence.

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.

Carcinosarcoma and squamous cell carcinoma of the renal pelvis associated with nephrolithiasis: a case report of each tumor type.

Both squamous cell carcinoma and carcinosarcoma of the renal pelvis are uncommon. We report on two cases, one carcinosarcoma and one squamous cell carcinoma of the renal pelvis. In the patient with squamous cell carcinoma of the left kidney, the tumor was neither detectable on preoperative radiological evaluation nor grossly visible in the surgical specimen. This patient, a 56-year-old man, presented with left lumbar pain, hematuria, fever, 4-5 kg weight loss, and untreated nephrolithiasis of the left kidney that had been diagnosed 20 years earlier. The second patient, an 87-year-old woman, also had a long history of left kidney nephrolithiasis and presented with left lumbar pain and hematuria. Both patients underwent nephrectomy for removal of the non-functioning hydronephrotic left kidney. In both cases, microscopic examination of the surgical specimen revealed squamous metaplasia and dysplasia in the pelvicalyceal mucosa, and islands of atypical squamous cells in the renal parenchyma. In the second case, the kidney also showed sarcomatous changes in the pelvis.

Management of complete ureteral obstructions with a transluminal puncture technique

INTRODUCTION The traditional delayed treatment of iatrogenic complete ureteral obstruction is open surgery. An easy endourological technique, transluminal re-canalization of the ureter by guide-wire puncture under fluoro-endoscopic control, which has been performed on 4 patients, is described. SURGICAL TECHNIQUE With the guidance of C-arm fluoroscopy, by moving the C-arm to different planes, the tip of the ureteroscope is directed to the correct plane to meet the obliterated proximal end of the ureter and under direct vision, transluminal puncture is performed using the stiff end of a 0.035-inch guide wire. Once the stiff end of the guide-wire is in the lumen of the proximal ureter, an ureteral catheter is introduced over the guide wire, the guide wire is then removed and reinserted through the ureteral catheter with its soft end leading and a double J catheter is inserted. Ureteral stricture, if later encountered, is treated with balloon dilatation. RESULTS Continuity of the ureter was restored in all 4 patients. The double J stents were removed 6 weeks later and a retrograde pyelography revealed resolution of the hydronephrosis without extravasation of urine. CONCLUSION Although a very satisfactory result was achieved in our cases, more cases are needed to show if it can be an alternative to conventional surgical repair. However, we believe that this minimally invasive technique can be used for short obliterated ureteral segments and neither delays nor does it preclude further management using open surgery.
