[Bladder neck sclerosis after transurethral resection of the prostate. "Study Group of the Puigvert Foundation"].
We reviewed 623 patients who underwent trans-urethral resection of the prostate (TURP) and 18 (2.8%) developed bladder neck contracture (BNC), in most cases symptomatic. Sclerosis appeared between 2 and 100 months after TURP (mean 9 months, median 19 months). Most were small prostates at the time of resection, with a mean resected weight of 10.5 g (SD 5.9), although there were no statistically significant differences between patients with and without contracture. Patients have been followed for a mean of 44.5 months. Three patients were not operated: two were asymptomatic and another one died one month postoperatively due to unrelated causes. The overall success rate was 75% and cold knife incision of the bladder neck accounted for a 90% success rate. Cold knife incision provides good long term satisfaction in patients with post-operative BNC. The difficulties in the study of this complication are analyzed.

[Clinical impact of idiopathic bladder instability].
Idiopathic vesical instability (I.V.I.), defined as the detrusor's spontaneous contraction during vesical filling or at its end, with a pressure higher than 15 cm H2O, is a urodynamic concept of unknown origin related to clinical disorders such as urinary incontinence, urgency-frequency syndrome, vesicoureteral reflux, repeat urinary infections, upper urological diseases due to pseudo-obstruction and morphological changes in vesicourethral X-rays. From January 1988 to January 1994, 2500 patients have been urodynamically examined. In 24% cases the diagnosis arrived at was vesical instability, 72% of them being I.V.I. I.V.I. was present as single diagnosis in 53% of prostate post-surgical incontinence, 71% of enuresis, 11% of clinically labelled stress incontinence, 46% of non-subsidiary incontinence, 16% of patients examined for prostatism, 55% of vesicoureteral reflux and 59% of repeat urinary infections.

[Intraprostatic prostheses].
Intraprostatic stents appeared as an alternative to surgery in high surgical risk obstructed patients. A critical review of the different types of endoprostatic prostheses is made. Finally we tried to establish the true cost/effectiveness ratio in our country, comparing the temporary prostheses with the indwelling catheter and the permanent prostheses with prostatic surgery.

Upper tract urothelial tumor after transurethral resection for bladder tumor.
We present a retrospective review of 30 patients who developed upper urinary tract tumors (UUTT) after having been diagnosed and treated for a bladder neoplasm. The mean patient age was 63 years (range 54-72). An average of 4.8 (range 1-10) transurethral resections (TUR) had been performed for bladder cancer prior to the appearance of UUTT. The length of time elapsed between the initial bladder TUR and the subsequent diagnosis of UUTT was variable, with increased incidence in the first 24-72 months (63.3% of the cases). In 21 cases (70%) the bladder tumor was multiple and in 28 (93.3%) the tumor was recurrent. In those patients with unilateral vesicoureteral reflux, an increased incidence of UUTT was found in the refluxing renal unit. In patients with poorly differentiated (grade 3 and grade 2-3) bladder tumors, UUTT was of the similar grade of anaplasia in 75% of cases. These observations, together with those previously published in the literature, allow us to recommend the use of excretory urography (IVP) every 2 years during the first 6 years of follow-up in patients treated for recurrent and/or multiple bladder tumor. Thereafter, follow-up would depend upon the individual clinical situation.

Value of electrical dispersion as a cause of urethral stenosis after endoscopic surgery.
We have evaluated the incidence of iatrogenic urethral strictures in a prospective study of 125 patients with a diagnosis of initial, superficial bladder tumors (without prior urethral instrumentation) and who were treated with endoscopic surgery. A global incidence of 12% was found after 24 months of follow-up with the strictures detected a mean of 9.5 months after the endoscopic procedure. These patients were divided into two groups. Group 1 was treated using standard transurethral resection (TUR) and group 2 underwent Nd:YAG laser photocoagulation. Both populations of patients underwent cystoscopic controls every 4 months as part of our standard follow-up protocol in bladder tumors. In the group of patients who underwent diathermy using a 24-F sheath (85 patients), the percentage of stenosis was 16.4%. In the patients treated with laser via a 21-F panendoscope (40 patients), the incidence of postoperative urethral stenosis was only 2.5%. We believe that the electrical dispersion generated by the unipolar electric current as well as the caliber of the operating instruments are factors which may influence the development of iatrogenic endoscopic urethral strictures.

Microscopic rice bodies in rheumatoid synovial fluid sediments.
To determine the clinical significance of the microscopic study of the synovial fluid (SF) sediment, 306 sediments were examined from 216 patients with the most frequently occurring acute and chronic arthropathies. The SF was obtained using a fine gauge needle. Microscopic rice bodies were seen in 53 (17.3%) of the samples studied. Forty-five (84.9%) of the samples in which rice bodies were observed were from patients with rheumatoid arthritis (RA) (p < 0.001); 34.9% of the 129 RA samples were found to contain rice bodies. The specificity of finding rice bodies in RA was 95.5%. Most rice bodies were composed of partly or totally hyalinized fibrinous material; in their interior, mononuclear cells were predominantly observed--most of them macrophagic in appearance. With less frequency the rice bodies exhibited central areas of fibrosis. Our results suggest that microscopic rice bodies are fibrinous particles derived from the entrapping of cells in the dense fibrin network present in inflammatory SF.

[Castleman's disease. A multifactorial study].
A case of Castleman's disease (hialino-vascular subtype) in a female patient 15-years-old is considered. Clinically there were isolated lymphadenopathies which relapsed after surgery and absence of general syndrome. Histoimmunological and electron microscopic studies were performed as DNA rearrangement and cytogenetics in order to exclude genetic abnormalities and monoclonality of this disorder. The role of follicular dendritic component in discussed.

[A nephrogenic adenoma during treatment with intravesical BCG].
Two patients who had undergone resection of a transitional cell bladder tumor presented with nephrogenic adenoma of the bladder during treatment with BCG. Nephrogenic adenoma presenting in the course of intravesical chemotherapy has been previously reported in 5 cases and can mimic tumor recurrence. Thus, we consider the present case to be of special interest.

[Renal hemangiomas: a clinical case and review of the literature].
Renal haemangiomas, an unusual cause of renal haematuria, are benign vascular dysplasias of uncertain etiology. Usually asymptomatic, their clinical manifestation is a unilateral renal haematuria associated or not to obstructive urological disease through accumulation of clots in the urinary tract and arterial hypertension when associated to a major arteriovenous shunt. Arteriographic diagnosis is based on the size of the vascular malformation but the absence of findings in the arteriography does not eliminate the presence of small-sized haemangiomas or microhaemangiomas responsible for the renal chronic haematuria, also labelled as "essential haematuria", which sometimes can be diagnosed through endoscopic examination of the renal cavities. This report presents one case of renal haemangioma which appeared as a massive, sudden haematuria and prompted haemodynamic instability requiring haemotherapy. Following arteriographic diagnosis, selective transarterial embolization was undertaken with three modified Gianturco's metal helicoids, to which the patient responded favourably. The report includes a review of the clinical, pathological, diagnostic and therapeutical features of renal haemangiomas.

Carcinoma in situ as a prognostic factor for G3pT1 bladder tumours.
G3pT1 bladder cancer has traditionally been regarded as a superficial tumour with a high risk of progression. We have studied 37 patients with initial G3pT1 bladder tumours treated between January 1981 and December 1985. They were divided into 2 groups according to the association with carcinoma in situ (Cis) at the time of diagnosis. Clinical behaviour was analysed at 5 years. The first group (without Cis) showed progression and recurrence rates similar to those of low grade, low stage bladder tumours. The second group (with Cis) had a similar rate of recurrence but their progression rate was 65%.

Electrohydraulic and ultrasonic lithotripsy in 100 consecutive cases of primary ureteral stones.
We have performed, between May 1985 and December 1988, in situ lithotripsy in 100 consecutive cases of primary ureteral stones, using electrohydraulic lithotripsy in 33 patients and ultrasonic lithotripsy in the remaining 67. After using similar instruments and surgical techniques in both groups, we have comparatively evaluated the complications encountered and the results obtained. With the electrohydraulic lithotripsy we have obtained a complication rate of 42% (operative and postoperative) and favorable results in 72.7% of the patients; using ultrasonic lithotripsy, the complication rate was 10.4%, and favorable results were obtained in 92.5%. We conclude that, at least in our experience, ultrasonic lithotripsy is less invasive and more successful than electrohydraulic lithotripsy in the treatment of primary stone disease.

Histological evaluation of superficial bladder tumors treated by Nd-YAG laser and transurethral resection.
Based on 3 study groups we have tried to analyze some concepts concerning the treatment of superficial bladder tumors by the Nd-YAG laser. In the first group of 34 superficial bladder tumors, we evaluated the accuracy of cold-cup biopsy in staging the tumor before treatment with the laser (100% for grade and 90% for stage). The possibility of identifying the tumoral grade in the lasered mass is 73%. In the second group of 53 random superficial bladder tumors we compared the effects of laser and transurethral resection (TUR) with regard to recurrence and progression after a 3-year follow-up: no significant differences are found between the treatments. In the third group the histologic changes in the bladder wall after treatment with the laser or TUR were evaluated by cold-cup biopsy (31 lasered cases and 24 resected cases) and by resector loop biopsy (11 lasered cases and 11 resected cases) between 12 and 24 months after treatment, without significant differences in terms of fibrosis.

Phase II trial of carboplatin and tegafur (Ftorafur) as induction therapy in squamous-cell carcinoma of the head and neck.
Cisplatin and 5-fluorouracil by continuous infusion combination produces a high response rate in squamous-cell carcinoma of the head and neck (SCCHN). Carboplatin (CBDCA) is a cisplatin analogue with lower emetic potential and nephrotoxicity, although the myelosuppression potential is higher. Tegafur (ftorafur, FT) is an analogue of 5-fluorouracil. It is absorbed well in its oral form and has moderate gastrointestinal and hematologic toxicity. This clinical trial tested the association of CBDCA i.v. plus FT p.o. in patients with SCCHN who had not been previously treated. Twenty-one patients were evaluable for response; the overall response was 62% (33% complete response, 29% partial response). Toxicity was moderate in most of the patients, although there was a treatment-related death.

Phase II trial of cisplatin and tegafur (Ftorafur) as initial therapy in squamous-cell carcinoma of the head and neck.
Cisplatin and 5-fluorouracil infusion combination produces a high response rate in squamous-cell carcinoma of the head and neck. Tegafur (Ftorafur) is an analog of 5-fluorouracil, and its oral form is well absorbed. This agent has a moderate toxicity. We report a study to determine the efficacy of the cisplatin (100 mg/m2, day 1) and tegafur (1,000 mg/m2 daily for 21 days) combination. Thirty-nine patients entered the study; 36 were evaluable for response. Overall response was 94%, with a 22% complete response. Toxicity was moderate. We conclude that the cisplatin and tegafur combination is active in untreated patients with head and neck cancer.
