[Extracorporeal shock-wave lithotripsy. An established treatment].

Extracorporeal shock wave lithotripsy (ESWL) is the most required urinary stone therapy in our country and in the rest of the world. In a way it has replaced the alternative treatments (open surgery, percutaneous nephrolithectomy, ureteroscopy). Nevertheless these therapeutic approaches have still its own indications. Although there is no a definitive agreement, it should be desirable a world-wide consensus where each therapy will have a exactly defined land with all potential of each management improved. We review ESWL technical aspects, its literature-based most accepted indications, adverse bioeffects and last, future improvements are considered.

[Benign presacral schwannoma producing obstructive uropathy. Clinical case and review of the literature].

We report a case of a presacral benign schwannoma which causes right hydroureteronephrosis without other clinical findings. After a fine-needle aspiration (FNA) biopsy under computed tomography (CT) guidance, a fusocellular tumour without athypia was demonstrated. With the initial diagnosis of benign schwannoma the patient was operated on, removing the tumour, and with the immunohistochemical examination (reactivity for S-100) this diagnosis was confirmed.

[Giant inguino-scrotal hernia of the bladder. Clinical case and review of the literature].

Bladder hernia is an uncommon condition with a frequency between 0.5 and 3%, reaching the 10% between patients older than 50 years. It's more predominant in males aged between 50 and 70. The diagnosis usually happens in the course of surgical repair of inguinal hernias, because the bladder hernia has no specific clinical findings. Management includes the resection or reduction of the bladder hernia, with de-obstruction of the lower urinary tract, if present, and repairmen of inguinal path. We report a new case and review the literature.

[Role of phosphate in recurrent calcium lithiasis. A current view].

OBJECTIVE: To analyze the biochemical impact of treatment with phosphates in patients with recurrent calcium lithiasis and hypercalciuria. METHODS: 20 patients were selected according to the following criteria: normal renal function, recurrent calcium nephrolithiasis, hypercalciuria, hypophosphatemia, normal calcium and low tubular phosphate reabsorption (TPR). The mean duration of treatment was 7.5 +/- 3.8 months. The pre and post-treatment phosphatemia, calciuria, phosphaturia and TPR were analyzed. The results were analyzed by the Wilcoxon statistical method. RESULTS: We found a moderate but significant decrease of calciuria (326.5 +/- 52-4 to 266.4 +/- 31.7 mg/24 h), while phosphatemia (2.21 +/- 0.09 to 2.52 +/- 0.30 mg/24 h) and TPR (65.7 +/- 6.3 to 71.3 +/- 4.1) increased significantly. Overall treatment was well-tolerated and no patient abandoned treatment. CONCLUSIONS: The short-term biochemical results obtained are similar to those reported in the literature. However, definitive conclusions cannot be made since treatment application is not standardized and studies that demonstrate its clinical efficacy are scanty.

[Penile cutaneous horn. A clinical case].

Contribution of a case report of cutaneous horn of penis surgically treated with extensive resection of the implantation base. A well differentiated, microinvasive epidermoid carcinoma was histopathologically demonstrated on a hyperkeratosis squamous papilloma. Although underlying lesions to cutaneous horn are usually benign, malignant changes have been reported in up to one third of cases; surgical treatment should therefore include extensive resection of the implantation base.

[Cystine calculi. Prevention with captopril. Clinical case].

Contribution of a case report of multiple cystine lithiasis with underlying homozygous cystinuria in a 5-year old male child. Following surgical management of the lithiasic episode the patient was followed-up with super-hydration, urine alkalinization and captopril prophylaxis. After three and a half years evolution, the patient has not developed new lithiasic episodes and maintains normal dibasic amino acids values in 24 h urine.

[Absorptive hypercalciuria type III or caused by renal loss of phosphates].

Contribution of a retrospective series of 16 patients with type II absorptive hypercalciuria over a total of 1.041 patients undergoing metabolic study due to relapsing renal lithiasis. Clinical history of lithiasis, biochemistry prior to treatment and instituted therapy were examined in all cases. Stones composition, radiologic appearance of lithiasis and evolution of biochemical parameters after medical treatment with a mixture of phosphates were also studied.

[Cystic dysplasia in the seminal vesicle. Case report and literature review].

Contribution of one case report of cystic dysplasia of the seminal vesicle with ipsilateral renal agenesis in a 32 year-old male presenting with primary infertility. The seminograms showed moderate astenoteratospermia while in the abdominal-pelvic ultrasound there were changes in the right seminal vesicle and right renal agenesis, which was confirmed with further complementary tests: UIV, transrectal ultrasound, urethrocystoscopy, arteriography and renal scan.

[Posttraumatic high-flow priapism in prepubertal age].

High flow priapism is an infrequent entity, generally following traumatic injuries in the genito-perineal area. Anamnesis, cavernous bodies blood gasometry and Doppler are the basic diagnostic tools for these condition. Therapeutical management is considerably different from that used for low flow venous priapism. Selective arteriography of the internal pudendal artery allows to locate the arterial lesion and, at the same time, to perform supraselective embolization of the lacerated cavernous artery which is currently considered the choice treatment. This paper presents the case report of a ten-year old patient successfully resolved through application of angioradiologic procedures.

[Entero-vesical fistula in primary lymphoma of the small intestine].

The introduction of self-expandable urethral endoprotheses for the management of relapsing urethral stenosis has required the development of a minimally invasive therapeutical approach of widespread acceptance by the urological community. The reason for its success is the simplicity of implantation and the low rate of complications up to date. This paper reports on a patient carrying a ¿Urolume¿ urethral endoprothesis for a relapsing bulbar urethral stenosis, which two years after implantation presents re-stenosis secondary to endoluminal inflammatory tissue growth. After two failure endoscopic resections, endoscopic removal of the prosthesis was required. Currently the patient carries a ¿Urocoil¿ spiral endoprosthesis to avoid tissular reaction. The therapeutical aspects found in the literature are reviewed, emphasizing the need of follow-up to detect complications, to improve indications and to select those patients that may be candidates for this treatment.

[A metabolic study of urolithiasis. Specificity, sensitivity, efficacy and reproducibility].

A preliminary diagnosis of the disease responsible for the stones is essential to allow appropriate medical treatment of renal stones. In this paper, the authors describe their diagnostic and treatment protocol based on computer-assisted urinary metabolic analysis. 413 subjects, divided into four groups, were prospectively evaluated to calculate their specificity, sensitivity, reproducibility and efficacy and to demonstrate the usefulness of this protocol.

[Granulated potassium citrate in the prevention of calcium oxalate lithiasis].

Since the approval of potassium citrate for the treatment of urolithiasis, there are many patients in other countries who have benefited from this drug. This paper describes the biochemical changes and tolerance seen in fifteen patients treated for one month with granulated potassium citrate. Some significant changes are observed in serum potassium and creatinine, and in urinary pH, citrate and potassium. Tolerance was good. Our results confirm that potassium citrate is an effective, easy to use, and well tolerated drug for the prophylaxis of oxalocalcium lithiasis.

[Eosinophilic cystitis. Study of the clinical course in 6 new cases and review of the recent literature].

Presentation of a series of 6 cases of eosinophilic cystitis diagnosed in our hospital and recorded in 1988-1993, with an average follow-up of 2 years from time of diagnosis. The actual trend with regard to this particular form of chronic cystitis is to abandon the idea of considering it a "benign" disease, basically due to its increasingly less uncommon association to bladder and/or prostate tumoral pathology (in the recent literature and most particular in the present series). Also, a relative increase in the frequency of occurrence of this disease is noted, because of chemoprophylaxis of surface bladder tumour with Mitomycin-C, an association which is increasingly frequent. Based on these 6 cases, a review of the most recent literature on this topic is made.

[Perineal radical prostatectomy in the age of laparoscopy].

With the advent of laparoscopic lymphadenectomy, attention has been focussed again to the perineal approach for cancer of the prostate. The high rate of postoperative impotence and the abdominal incision required had made radical perineal prostatectomy unpopular. From August 1990 to July 1991, 76 patients with localized prostate cancer were surgically treated at the University of St. Louis. These patients were divided into three groups; group A comprised 26 patients who were submitted to laparoscopic lymphadenectomy and radical perineal prostatectomy, group B comprised patients treated by laparoscopic lymphadenectomy and radical retropubic prostatectomy, and group C or controls underwent open lymphadenectomy and radical retropubic prostatectomy. Fifty-three patients were sexually potent preoperatively but only 20 (7 from group A, 5 from group B and 8 from group C) were considered for preservation of the neurovascular bands. All the patients were followed for a minimum of one year. Comparison of these three groups revealed significant differences for perioperative bleeding and postoperative hospital stay in favor of Group A. The overall stress incontinence rate was 5.3% and the complications ranged from 4.1% for group C and 29.1% for group B. The postoperative sexual potency ranged from 57% for group A to 75% for group C, the differences not being statistically significant. Radical perineal prostatectomy is as valid as radical retropubic prostatectomy for localized prostatic cancer and has the advantages of less bleeding and a faster recovery, particularly if combined with laparoscopic lymphadenectomy.
