Pro-inflammatory cytokine response of the fluid contents of spermatoceles and epididymal cysts.

The aim of the study was to determine the cellular contents and concentrations of interleukin 6 (IL-6), interleukin 8 (IL-8) and tumour necrosis factor alpha (TNF-alpha) in fluids of patients with spermatocele or epididymal cyst. Twenty-five symptomatic patients, 14 with epididymal cysts and 11 with spermatoceles, were included in the study. Fluids were obtained during surgical excision of the cysts and cytological smears were stained with May-Gruenwald-Giemsa to establish cell components. The concentrations of IL-6, IL-8 and TNF-alpha were measured by chemiluminescent immunometric assay. Cytological analysis of the fluids demonstrated various sperm forms ranging from immature germ cells to degenerated spermatozoa without inflammatory cells such as neutrophils and macrophages. The concentrations (mean+/- SEM, pg/mg protein) of IL-6, IL-8 and TNF-alpha were 13.52 +/- 1.40, 22.20 +/- 2.43, 3.51 +/- 1.43 in spermatocele fluids and 5.76 +/- 0.48, 11.57 +/- 1.89, 2.53 +/- 0.41 in epididymal cyst fluids. Both IL-6 and IL-8 concentrations in the spermatocele group were higher than in the epididymal cyst group (P < 0.0001). There were no differences in TNF-alpha concentrations between the groups (P > 0.05). These findings indicate that local production of pro-inflammatory cytokines is involved in cyst formation. The presence of immunologic activation in these fluids advocates a policy of selective surgical intervention in patients with spermatocele or epididymal cyst.

Intracavernosal adrenalin injection in priapism.

Prolonged erection is a rare problem in urology but it must be treated effectively. The most common etiological factor is intracavernosal vasoactive agent injection for diagnosis or treatment of erectile dysfunction. The aim of this study was to evaluate the efficacy of intracavernosal adrenalin injection alone in the treatment of priapism. Nineteen patients with prolonged erection were evaluated. Seventeen out of the 19 prolonged erections were due to intracavernosal vasoactive agent injection and the remaining two were idiopathic. In all cases 2 ml adrenalin (1/100 000) was injected in each cavernosal body. In the patients who did not respond to the first injection, repeated adrenalin injections were performed at 20 min intervals. Blood pressure and heart rate were monitored during the injections. Detumescence was achieved in ten (53%) patients after the first injection. Repeated adrenalin injections (2-5 injections) were required in nine patients and eight (42%) of them achieved detumescence. Only one (5%) patient who had 26-h prolonged erection could not achieve detumescence. There was no significant difference in blood pressure and heart rate during the monitoring of the patients when compared to the initial values. No standard treatment method has yet been described for prolonged erection. Repeated aspirations and irrigations for treatment of prolonged erection are problematical applications both for patients and urologist. Intracavernosal adrenalin injection alone can be used with high efficacy and safety for the treatment of prolonged erection especially in patients with a short duration of erection.

Results of extracorporeal shock wave lithotripsy in the pediatric age group.

OBJECTIVE: In this study we aimed to show the efficacy of extracorporeal shock wave lithotripsy (ESWL) for urinary stone disease in the pediatric age group and to evaluate the complications encountered after the treatment. METHODS: 67 children with 109 stones underwent ESWL, using a Dornier MPL 9000 lithotriptor. Styrofoam boards were used to protect the lungs. KUB and chest radiographs were taken on the day after treatment. If stone-free status was achieved, the patient was followed with ultrasonography and urine analysis every 6 months for 2 years. If fragments < 4 mm were present, follow-up was repeated every 3 months. RESULTS: Stone size ranged from 0.5 to 3.5 cm. 71 renoureteral units underwent a total of 129 ESWL sessions. Retreatment was required in 28 patients. The mean number of sessions per unit was 1.8. A stone-free status was achieved in 60 renoureteral units. The overall success rate was 88.6%. The composition of the stone was mixed calcium oxalate and phosphate in the majority of the patients. Auxiliary procedures used were push-back, ureteroscopic stone removal, and open surgery. Hematuria, colics and fever over 38 degrees C were the complications encountered after the treatment. CONCLUSIONS: ESWL is the first-line treatment for renal and upper ureteral calculi. However, larger stones which will require several ESWL sessions and consecutively increased number of shock waves are best treated with percutaneous nephrolithotomy plus ESWL. Patients with congenital anomalies necessitating surgical reconstruction are the best candidates for operation.

Detection of metastatic bone lesions in patients with prostate carcinoma: 99Tcm-monoclonal antibody imaging.

Bone scintigraphy has been shown to be sensitive in determining bone involvement in patients with malignancy, but it does not allow the assessment of bone marrow lesions in early disease. The aim of this study was to detect bone marrow invasion using 99Tcm-labelled monoclonal antigranulocyte antibody (AgMoAb) in patients with prostate carcinoma. We studied 56 patients whose mean (+/- S.D.) age was 67 +/- 7 years. The mean prostate-specific antigen level was 6.1 ng ml-1 (normal range 0-5 ng ml-1). Twelve patients were in stage A, 16 in stage B, 17 in stage C and 11 in stage D. Six patients had been receiving chemotherapy and four patients radiotherapy before scanning. Bone scans were obtained 2 h after the intravenous injection of 555 MBq 99Tcm-methylene diphosphonate (99Tcm-MDP). Within a week, bone marrow imaging was performed 4 and 24 h after the injection of 555 MBq 99Tcm-AgMoAb. Metastatic bone lesions were detected on the 99Tcm-MDP scans of 14/56 (25%) patients, of whom one was in stage A, two in stage B, four in stage C and seven in stage D. Hypoactive lesions in bone marrow were detected in 25/56 (45%) patients, of whom two were in stage A, five in stage B, seven in stage C and 11 in stage D. Bone marrow metastases were confirmed in six patients by computed tomography (CT) and magnetic resonance imaging (MRI) and in two patients by marrow aspiration biopsy. A false-positive immune scintigram was found in three patients previously receiving radiotherapy or chemotherapy. We suggest that 99Tcm-AgMoAb scintigraphy is a sensitive procedure for the detection of bone marrow lesions. However, the reason for false-positive and false-negative results should be considered and CT, MRI and marrow biopsy should be performed when clinically necessary.

Anti-bacterial activity of the fluid contents of spermatoceles and epididymal cysts.

OBJECTIVE: To show that the fluids obtained from spermatoceles and epididymal cysts are not infected, even though they may be present for long periods, and that these fluids have bactericidal activity. MATERIALS AND METHODS: Sixteen patients, 13 with a spermatocele and three with an epididymal cyst, were included in the study. Protein, glucose, chloride, inorganic phosphorus, calcium and magnesium contents were measured and cultures of the fluids were carried out. Bactericidal activity against the Escherichia coli NTCC 10418 clone was tested in different dilutions. RESULTS: Biochemical analysis showed that the protein, glucose and ionic content of the fluids was lower than that of serum, except for chloride. Microbiological cultures were negative for all samples. A significant bactericidal effect was obtained with 1/1 dilution and no reproduction was seen with this dilution. CONCLUSION: These findings indicate that the fluids within spermatoceles and epididymal cysts do not become infected under normal circumstances.
