The relationship between clinical stage, natural killer activity and related immunological parameters in adenocarcinoma of the prostate.
Several immunological in vitro tests were performed on peripheral blood mononuclear cells of patients with adenocarcinoma of the prostate, stages A, B, C, D. The cytotoxicity of effector natural killer cells towards K-562 targets decreased with increasing disease spread, while their percentage was not significantly changed. The proportion of CD4 (helper/inducer) cells tended to fall with tumor advance, but the proportion of CD8 (suppressor/cytotoxic) cells remained almost constant. Secretion of interleukin-2 from peripheral blood mononuclear cells was diminished with disease progression. Pretreatment of a patient's lymphocytes with cimetidine (antagonist of H-2-bearing suppressor T cells) or indomethacin (inhibitor of prostaglandin synthesis) enhanced natural killer activity. Our data point to the existence of aberrant immune functions in early stages of carcinoma of the prostate and to aggravation of these immune abnormalities in advanced disease.

Absence of peripheral-type benzodiazepine binding sites in renal carcinoma: a potential biochemical marker.
In an attempt to identify a tumour marker, we investigated peripheral-type benzodiazepine binding sites (PBS) in kidney specimens obtained from patients who underwent nephrectomy due to a renal mass. [3H]PK 11195, an isoquinoline carboxamide derivative, was used as a ligand. Binding assays were conducted on samples of membrane homogenate taken from both the healthy portion and the tumour site of the kidney. It was found that binding characteristics of benign tumours and normal kidney tissues were not significantly different, i.e. equilibrium dissociation constants of 2.20 +/- 0.73 and 2.38 +/- 0.98 nM, respectively, and maximal number of binding sites of 3190 +/- 1081 and 4189 +/- 998 fmol/mg protein, respectively. In contrast, no PBS were detectable in renal carcinoma. The absence of PBS in malignant renal tissues may serve as a biochemical marker for tumours of the kidney.

Induction of anesthesia with propofol in urological outpatient surgery.
Propofol (Diprivan) in a new formulation, a short-acting intravenous anesthetic, was used as an induction agent for short urological procedures. Forty unpremedicated patients were treated with either propofol or thiopental in a randomized study. The onset of anesthesia and duration of apneic period were prolonged and the decrease in systolic blood pressure was more profound in the propofol group. Heart rate was less stable and recovery time was longer in the thiopental group. Other parameters, such as quality of anesthesia, acceptability of the drug or rate of side effects, were similar in both groups. These results suggest that propofol in a new formulation is a suitable agent for short urological procedures in outpatient surgery.

Adrenal myelolipoma simulating virilizing adrenal tumor.
We describe a case of adrenal myelolipoma that simulated clinically and biochemically a virilizing adrenal tumor. The tumor was removed surgically. The preoperative diagnosis of adrenal myelolipoma can be made by the characteristic appearance on ultrasonography, computerized tomography and in equivocal cases by guided needle biopsy.

Fracture of double-J ureteric stents: a report of two cases.
Two cases are reported of fracture of the double-J ureteric stent during its prolonged placement for extracorporeal ultrasound shock wave lithotripsy (ESWL). The causation of such fracturing is discussed and it is recommended that double-J stents employed in long-term ESWL be renewed within 5 months of their initial placement.

A safe surgical technique for the infradiaphragmatic removal of caval tumor thrombus complicating renal cell carcinoma.
The management of patients with renal cell cancer extending to the vena cava is controversial and challenging. Careful planning of the operative procedure, adequate exposure, complete mobilization of the retrohepatic vena cava and control of the hepatic venous effluence will allow patients with retrohepatic vena caval occlusions to be managed safely and successfully. The major advantage of this technique is the minimizing of both peroperative bleeding and circulatory and biochemical disturbances of the liver due to the interruption of the blood flow.

Preoperative prediction of results of prostatectomy by a symptom score and radionuclide uroflowmetry.
A review of preoperative and postoperative symptom scores and radionuclide uroflowmetry in patients undergoing prostatectomy for benign prostatic hyperplasia indicates that there may be certain findings that can help to predict postoperative results. A statistically significant difference was obtained comparing the postoperative results of the symptom score and radionuclide uroflowmetry with the results obtained preoperatively. The correlation between the preoperative ejection fraction and the postoperative total symptom score and irritative score showed a good correlation.

The use of distilled water as an irrigating fluid in patients undergoing transurethral resection of the prostate.
Thirty patients undergoing transurethral resection of the prostate using distilled water as an irrigating fluid were studied. There was no significant change in the serum concentration of the variables studied (preoperatively compared to postoperatively) as possible indicators of haemolysis or absorption of irrigating water such as sodium, potassium, albumin, total protein, creatinine, uric acid, urea, haemoglobin, haematocrit and haptoglobin. The mean value of plasma haemoglobin (P-Hb), observed immediately postoperatively and reflecting the magnitude of haemolysis, was delta 294.8 mg/l. There was a good correlation between P-Hb and the inflowing irrigating distilled water (r = 0.69). The P-Hb variation (delta) correlated with resection time and with the weight of the resected prostate (r = 0.54 and r = 0.52, respectively). A good correlation was also found between resection time and delta body weight which reflects the amount of water absorbed (r = 0.67) and between delta body weight and the inflowing irrigating water (r = 0.61). Our study shows that distilled water can be used as an irrigating fluid quite safely. The advantages of distilled water outweigh the disadvantages which can be avoided easily if proper attention is given.

Quantitation of renal uptake of technetium-99m DMSA using SPECT.
Quantitative single photon emission computed tomography (SPECT) methodology based on calibration with kidney phantoms has been applied for the assessment of renal uptake of [99mTc]DMSA in 25 normals; 16 patients with a single normal kidney; 30 patients with unilateral nephropathy; and 17 patients with bilateral nephropathy. An excellent correlation (r = 0.99, s.e.e. = 152) was found between SPECT measured concentration and actual concentration in kidney phantoms. Kidney uptake at 6 hr after injection in normals was 20.0% +/- 4.6% for the left and 20.8% +/- 4.4% for the right. Patients with unilateral nephropathy had a statistically significant (p less than 0.001) low uptake in the diseased kidney (7.0% +/- 4.7%), but the contralateral kidney uptake did not differ from the normal group (20.0% +/- 7.0%). The method was especially useful in patients with bilateral nephropathy. Significantly (p less than 0.001) decreased uptake was found in both kidneys (5.1% +/- 3.4% for the left and 6.7% +/- 4.2% for the right). The total kidney uptake (right and left) in this group showed to be inversely correlated (r = 0.83) with serum creatinine. The uptake of [99mTc]DMSA in single normal kidney was higher (p less than 0.001) than in a normal kidney (34.7% +/- 11.9%), however, it was lower than the total absolute uptake (RT + LT = 41.5% +/- 8.8%) in the normal group. The results indicate that SPECT is a reliable and reproducible technique to quantitate absolute kidney uptake of [99mTc]DMSA.

Effect of diclofenac sodium (Voltaren) on spermatogenesis of infertile oligospermic patients.
The effect of the prostaglandin synthesis inhibitor diclofenac sodium (Voltaren) on spermatogenesis in infertile oligospermic patients has been studied. Diclofenac sodium was given orally at a daily dose of 100 mg for 30 days. Seminal fluid parameters were evaluated. Group II with high levels of seminal prostaglandin showed a statistically significant increase in the number and motility of spermatozoa (p less than 0.01), whilst no significant variations were observed in patients of group I with normal values of seminal prostaglandin.

Cancer of the prostate: is there a need for aggressive treatment?
Adenocarcinoma of the prostate constitutes 18% of all cancers in men, and is a major cause of neoplastic death second only to carcinoma of lungs and large bowel. In spite of the high incidence of the disease, there is still disagreement as to the right treatment. In our study we reviewed 101 patients in stages T0b, T1 + T2, T3 (N0M0) who were treated by nonradical prostatectomy and no other treatment. The follow-up of these patients was 58 months. The actuarial 5- and 10-year survival according to stage was respectively: 91.30 and 64.62% in stage T0b; 60.61 and 34.11% in stage T1 + T2, and 41.67% in stage T3. Survival rates resembled those quoted in the literature. Our results justify a less aggressive approach to carcinoma of the prostate.
