[Syringocele of the Cowper's gland].

OBJECTIVE: To report an additional case of syringocele of Cowper's glands and briefly review its etiopathogenesis, diagnosis and treatment. METHODS/RESULTS: A 26-year-old male consulted for a recent voiding syndrome and chronic postvoid dribbling. A voiding cystourethrogram demonstrated a syringocele, which was confirmed during endoscopic treatment. CONCLUSIONS: Syringocele or cystic dilatation of Cowper's gland duct usually has a congenital etiology. There are four morphological types: simple, perforated, imperforate and ruptured. Diagnosis is made by voiding cystourethrography and confirmed by endoscopy. Transperineal ultrasound was also utilized for the diagnosis. Treatment is by endoscopic incision.

[Extrinsic ureteral obstruction secondary to appendiceal mucocele].

OBJECTIVE: To report a case of extrinsic ureteral obstruction arising from mucocele of the appendix and review the clinical, diagnostic and therapeutic aspects of this appendiceal pathology of interest in urology. METHODS: A 71-year-old female patient that had previously undergone radical gynecological surgery and postoperative radiotherapy presented with right lumbar pain. Patient evaluation by ultrasound, IVP and CT showed a pelvic mass causing right extrinsic ureteral obstruction. Release and reinsertion of the right ureter and appendectomy were performed. RESULTS: The anatomopathological study showed an appendiceal mucinous cystadenoma. The patient is asymptomatic after surgery. CONCLUSIONS: Appendiceal mucocele is a dilatation of the vermiform appendix due to collection of mucoid material that is frequently produced by a cystadenoma. The presenting feature is usually that of acute appendicitis. The definitive diagnosis is based on the anatomopathological findings. Treatment is by appendectomy for the benign tumors and by right hemicolectomy in a second stage procedure for malignant tumors. This appendiceal pathology should be taken into account in the differential diagnosis of right extrinsic ureteral obstruction.

[High-flow priapism in the pediatric age: review].

OBJECTIVE: To review the literature on high flow priapism in children and analyze the etiology, pathophysiological mechanism, diagnostic tests, treatment and complications. METHODS: The literature is reviewed and an additional case of posttraumatic arterial priapism in an 11 year-old boy treated at our hospital is presented. RESULTS: 24 cases of high flow priapism in children were found; 18 had a history of genitoperineal trauma, 5 had sickle cell anemia and one child had Fabry's disease. Diagnosis was based on patient history, intracavernous blood gases and echo doppler findings. Fourteen patients with posttraumatic priapism, one patient with sickle cell anemia and the child with Fabry's disease were treated by pudendal arteriography with embolization. The immediate results and erectile function were good. CONCLUSIONS: Genitoperineal trauma is the most common cause of arterial priapism in children. High flow must be considered in children with sickle cell disease and priapism that do not respond to conventional treatment. Pudendal arteriography with embolization is the treatment of choice. Erectile function is recovered after treatment.

[Nephrogenic adenoma: study of 9 cases, including one of the urethra in a 14-year-old male].

OBJECTIVES: To review our series of nephrogenic adenoma and compare our results with those reported in the literature. METHOD: The records of our Department of Pathology were reviewed to determine the cases of nephrogenic adenoma diagnosed at our center. The clinical features, diagnostic aspects, pathological findings, treatment and outcome are presented. RESULTS/CONCLUSIONS: Nephrogenic adenoma is a rare lesion, probably arising from nephrogenic metaplasia caused by injury to the urothelial mucosa. The site of presentation is frequently the bladder, followed by the urethra. The diagnosis is based on the histopathological findings, which can be occasionally equivocal. The cases described in the present series were benign. To date there is no established therapeutic approach. We performed TUR in two patients, antibiotic therapy was administered in one patient and 4 patients were managed conservatively. Two of our patients had no control evaluation following biopsy of the lesion. In 2 of the 4 patients that were managed conservatively, the lesion remitted spontaneously.

[Laparoscopic extraperitoneal suspension of the neck of the bladder in stress incontinence: midterm results].

OBJECTIVE: There are few reports on the medium- and long-term outcomes of laparoscopic suspension of the bladder neck. METHODS: Our medium-term results in 24 patients with genuine stress urinary incontinence who underwent surgery from March, 1994 to July, 1996 are presented. The patients had a mean follow-up of 18 months. RESULTS: Although the initial results were encouraging, some failures appeared in the medium-term and incontinence recurred in 20%. CONCLUSIONS: The overall outcomes of laparoscopic suspension of the bladder neck did not differ from those achieved with the original technique of Pereyra-Stamey and the mean operating time was longer. The mean length of stay did not decrease and the rate of postoperative complications was similar. All the foregoing reasons have led us to abandon this procedure in the treatment of genuine stress urinary incontinence.

[Injection of autologous fatty tissue in the bladder submucosa: experimental study in swine].

The results achieved by the use of inert materials via endoscopic injection for the treatment of urological pathologies have been disappointing. Furthermore, these materials are costly, carry the risk of migration and may not be tolerated locally. Autologous fatty tissue, however, is not costly and is tolerated better. The authors have conducted an experiment in the pig to evaluate the degree of resorption and persistence of autologous fat injected into the bladder submucosa. The results show that submucosal injection of autologous fat acts like an autograft and persists as mature fatty tissue. The degree of resorption and/or steatonecrosis is directly related to the amount injected; the smaller the amount used the better the results.

[Endoscopic resection of tumor of the renal pelvis].

We report on a patient who was submitted to percutaneous resection of a solitary, low grade urothelial transitional cell tumor of the renal pelvis. A review of the literature shoned endourologic treatment to be a valid in carefully selected cases. The measures to minimize the risk of tumor spread and the good results obtained are discussed. However, a longer follow up and larger series are necessary in order to draw definitive conclusions.

[Cystic pyeloureteritis. Our approach].

We report a case of massive cystic pyeloureteritis that had been diagnosed by ureterorenoscopy in a patient with recurrent urinary infection and episodes of nephritic colic. The reports published in the literature indicate there is no specific treatment for this disease whose etiology is unknown. Its pathogenesis has not been well-established and it is difficult to distinguish from other urothelial filling defects. Although it has also been reported that it may progress to malignancy, we believe that the therapeutic approach should be conservative.

[Bladder bilharziasis: report of a case].

Herein we describe a case of vesical bilharziasis in a Spanish patient who became infected during a trip to an endemic area. The characteristic features of the disease and particularly its relationship to squamous type bladder tumors are discussed with a special focus on treatment with Praziquantel.

[Bilateral adrenal masses during clinical staging of renal carcinoma].

We report a case of renal adenocarcinoma with bilateral adrenal masses at the time of diagnosis. Owing to the methods currently used for clinical staging, this association is no longer infrequently observed. Experience has demonstrated the value of the diagnostic techniques in this condition. The use of some of these techniques will depend on the findings during clinical staging of the tumor. Well-selected cases with metastasis to the adrenal gland can benefit from surgery.

[Spontaneous rupture of endo-ureteral catheter].

A patient with bilateral staghorn calculi treated by ESWL and endourologic placement of a double-J catheter is described. The patient was lost to follow-up for 18 months after catheter placement. When the patient was seen again, examination revealed a fractured catheter which warranted retrieval by combined nephrectomy and URS.

[Percutaneous endo-retro-pyelotomy: an elective treatment method in stenosis of the uretero-pelvic junction].

Fifteen adult patients diagnosed as having congenital stricture of the ureteropelvic junction were treated by percutaneous endoureteropyelotomy. Our results were clinically satisfactory in 85.7% (excellent acured 57.1%, good/with occasional mild discomfort 28.5%). Radiologically, 64.2% were normal and 14.2% had mild ectasia but good renal function. No clinical improvement was observed in 14.2% and 21.4% had persistent hydronephrosis indicating the procedure had failed. The most important complication was intraoperative hemorrhage from effraction of an inferior polar artery which required a conventional lumbotomy procedure and Anderson-Hynes pyeloplasty. The foregoing results, with the limitations inherent in data from a small series, indicate that endoureteropyelotomy is the procedure of choice in the treatment of congenital UPJ strictures in the adult patient.

[Endoscopic injection of autologous adipose tissue in the treatment of female incontinence].

We describe a new procedure utilizing autologous fat instead of teflon injection in the treatment of female urinary incontinence that is equally useful in correcting postadenomectomy incontinence in the male and vesicoureteral reflux. We have used this new procedure over the past 4 months in 10 patients with urinary stress incontinence and no concomitant cystocele. The procedure is performed under spinal anesthesia. Small cylinders of subcutaneous abdominal fatty tissue are obtained by microliposuction. The fat graft in the form of four 10 ml. wheals is then injected in the vesical neck. We emphasize that this technique is simple and there are no complications. The low cost of this technique requiring a 24 h stay at the hospital affords additional advantages. Likewise, the procedure can be repeated or subsequent surgical procedures can be performed without difficulty in the event correction is unachieved.
