Urodynamic parameters in preoperative evaluation of patients with bladder tumours.

Urodynamic evaluation was done in 28 patients with various staged bladder tumours. In 12 patients with superficial bladder tumours all urodynamic parameters were in normal range. Thirteen patients of 16 with invasive bladder tumours had low capacity of bladder and 5 of them also had involuntary contractions. In this study we suggest that urodynamic parameters in patients with bladder tumour became significantly abnormal when the first tumour invasion is seen at the muscular layer of the bladder (p < 0.05); so compliance significantly decreased and the other pathological conditions were followed (p < 0.05).

A urodynamic evaluation of patients with renal, upper and lower ureteric stones.

OBJECTIVE: To investigate the urodynamic variables of the patients with renal, upper and lower ureteric stones and compare the results according to the location of the stone. PATIENTS AND METHODS: Pre-operatively, 49 patients with kidney, upper and lower ureteric stones were evaluated to determine bladder capacity, compliance and urine volume at first sensation. Patients with urinary tract infection, neurogenic pathology and bladder outlet obstruction were excluded. The patients were divided into two groups; 20 patients with kidney and upper ureteric stones and 29 patients with lower ureteric stones. RESULTS: The mean bladder compliance, bladder capacity and volume at first sensation were all significantly lower in patients with lower ureteric stones (P = 0.026, P = 0.005 and P = 0.042, respectively). These patients also had more prominent irritative symptoms, urgency and frequency. However, the mean values of bladder capacity, compliance and volume at first sensation were within normal limits in both groups. CONCLUSION: Lower ureteric stones cause more irritative bladder symptoms than do renal and upper ureteric stones and lower ureteric stones should be considered as a possible cause of sensory urgency.

Comparative early results of transurethral electroresection and transurethral electrovaporization in benign prostatic hyperplasia.

OBJECTIVE: To compare the results of conventional transurethral electroresection of the prostate (TURP) and transurethral electrovaporization (TUEP) in patients with symptomatic benign prostatic hyperplasia. PATIENTS AND METHODS: The study comprised 46 patients with moderate or severe symptoms of prostatism and a maximal flow rate of < 15 mL/s. Pre-operatively, all patients underwent a digital rectal examination and the determination of prostatic volume by ultrasonography, and a symptom score, the maximal flow rate, post-void residual urine, routine biochemical variables and serum prostate specific antigen were measured. The haematocrit and blood Na+ levels were also determined pre-operatively and again 24 h after the operation. Patients were divided randomly into two groups: the first underwent a conventional TURP and the second TUEP using 240-300 W of cutting current. Three months after operation, all the variables were remeasured and the values compared with those before treatment and between the groups. RESULTS: The improvements in symptom score, maximum flow rate and residual urine were slightly better after TURP than after TUEP but the differences between treatments were not statistically significantly different. However, TUEP used slightly less irrigant solution, allowed earlier removal of the urethral catheter, required no blood transfusions and was easier to perform. CONCLUSION: Although the improvements in the objective variables 3 months after TUEP were almost the same as after TURP, there were advantages in using less resources: further studies with more patients and a longer follow-up are required to determine the efficacy and safety of this procedure.

Evaluation of impotent men with intracorporeal injection of papaverine and colour Doppler ultrasound.

Fifty impotent patients have been evaluated with intracorporeal injection of papaverine and colour Doppler ultrasound. The papaverine tests were negative in 34 of 50 patients. Nineteen of 34 patients with negative papaverine results showed normal colour Doppler findings. In 14 of 16 patients with positive papaverine results the colour Doppler analysis revealed normal structure and functions. Correlation between intracorporeal papaverine injection and colour Doppler ultrasound results was found in 59% (p < 0.01). We concluded that intracorporeal papaverine injection is an effective, simple diagnostic test for beginning evaluation of impotent men. However, this screening test should be supported by colour Doppler ultrasound.

Treatment of renal hydatid disease by pedicled omentoplasty.

Renal hydatid disease is uncommon and accounts for only 2 to 3% of all hydatid diseases. The treatment of choice is surgical. Medical therapy is not always satisfactory and radical cure depends mostly on removal of all affected tissue. There is controversy concerning the treatment of residual cavity after evacuation of the cyst. For this problem we performed the pedicled omentoplasty in 4 patients with renal hydatid disease. To our knowledge, this method has not been described previously for renal hydatid disease. Cystectomy with pedicled omentoplasty appears to be safe and effective in the management of renal hydatid disease.

Antispermatozoal antibody values after varicocelectomy.

Although there are many causes of the production of antispermatozoal antibodies, there are still unknown aetiological factors. Antispermatozoal antibodies were investigated in the postoperative period in 25 infertile men with varicocele whose antispermatozoal antibody tests were negative in the preoperative period. Antispermatozoal antibodies were found in the serum in 4 of the 25 (16%) infertile men after varicocele operation. Postoperative genital infections were detected in 6 patients and antispermatozoal antibodies were present in only 2 of them. The correlation between these antibodies and varicocele has been demonstrated but there is no report on the association of antibodies with varicocelectomy in the literature to date.

Two serious complications of circumcision. Case report.

Twins aged 19 years presented having been circumcised by an unqualified "itinerant circumciser" at the age of 2 1/2. In one the glans penis and corpus cavernosum were invisible, and the external urethral meatus was at the level of the mons pubis; the other had defects of the glans and corpus, iatrogenic hypospadias, and the end of the penis was protruding only 1.5 cm from the mons pubis. Both underwent successful reconstruction, and are normally sexually active.

Persistent müllerian duct syndrome.

Persistent müllerian duct syndrome is a rare form of pseudohermaphroditism, in which well developed müllerian structures are present in an otherwise normal male, possibly resulting from absence of müllerian duct inhibiting factor. Two cases of the syndrome are presented. The diagnosis, as in most cases, was confirmed at herniorrhaphy or exploration for undescended testis.

[Organochlorine pesticide residues in raw and roasted coffee and their degradation during the roasting process].

An analysis method for determination of organochloro pesticides in green and roasted coffees was developed. 17 Arabica and 2 Robusta coffees originating from 11 countries were investigated. With the exception of two samples the amounts of pesticide residues found in the green coffees were considerably lower than the amounts permitted, according to the "Höchstmengenverordnung". In 2 coffees no residues were detectable. The residues were reduced to insignificant amounts during the roasting process. The degradation rates ranged from 85% to 100%. Since the residues detected in all of the roasted coffees were insignificant, no further investigation of the corresponding beverages was necessary.

Metastatic carcinoma of the gallbladder due to renal cell carcinoma in the ectopic kidney.

We report a rare case of secondary involvement of the gallbladder by metastatic renal cell carcinoma originating from ectopic kidney. The first diagnosis of the patient is a gallbladder carcinoma due to a polypoid mass within the gallbladder. The preoperative examinations revealed that there was also a synchronous renal cell carcinoma. The histopathologic examination of the polypoid mass and kidney after operation revealed the resected polypoid mass to be metastasis of renal cell carcinoma.
