[Vesico-uterine fistula, a rare complication of cesarean section].

We present the case of a vesicouterine fistula secondary to a caesarean section indicated due to the disproportion the pelvis and the head of the baby. This kind of fistula is due fundamentally to obstetric causes, especially to caesarean sections in developed countries and to prolonged labour in developing countries. The commonest clinical presentation is urinary incontinence in the form of continuous or intermittent urinary leaks. Surgical treatment is generally the therapy of choice, although, in the case of small fistulas, conservative treatment is feasible. The best form of prevention is correct indication of caesarean section and careful surgical technique.

[Endoscopic resolution of complications caused by urethrovesical suspension].

We presented a total of ten women which referred a varied syntomatology secondary to a bladder foreign body due to the suture employed in the stress incontinence surgery in which urethrovesical suspension techniques were performed. In these patients, to six a Marshall-Marchetti-Krantz technique was practised, to three modified Burch procedure and to the left a suspension according to Raz method. It is described the varied clinic they presented, the necessity of endoscopic study to confirm and the results after solving the 90% of these cases using endoscopic techniques. It is concluded that is not mandatory the employment of non absorbable suture to perform the suspension techniques and in the opposite of the usual tendency of the authors recurring to open surgery, this complication can be solved endoscopically and in ambulatory regime in the most of these cases.

[Study of urinary outflow in pregnancy].

Anatomical and physiological changes in the urinary tract develop during pregnancy. These changes may affect the urinary outflow. Urinary symptoms may develop during pregnancy in previously asymptomatic patients. Most of these symptoms will vanish after delivery. Some of them remain and others will become worse in consecutive pregnancies. A study was designed to compare if there was any difference in the urinary outflow between pregnant and non-pregnant women. Changes in the urinary outflow at different gestacional ages were studies too. In general, the urinary volume is higher in pregnant than in non-pregnant patients. Having said this, during the pregnancy this volume decrease in the third trimester. Peak urinary outflow is higher in pregnancy, being statically significant during the second and third trimester. Opposite to the non-pregnant patient, peak urinary outflow does not decrease with urinary volumes over 500 ml in pregnant patients. Significant differences were not found in the mean urinary outflow in both groups.

[Bladder paraganglioma. Report of a case and review of the Spanish literature].

Paragangliomas are rare tumours of the bladder accounting for 0.06% of all vesical tumours. This paper reports one case of vesical paraganglioma in a young female patient that has the singularity of being associated to melanin pigmentation. A review is made of cases treated in Spain, adding some comments on the signs and symptoms presented, as well as the diagnostic and therapeutical methods used in this unusual condition.

[Pyelocaliceal diverticuli].

Pyelocalyceal diverticula are eventrations of the upper collector system in an intraparenchymatous location which communicate with the main collector system through a narrow channel. They have a thin wall and are lined with a transitional cells epithelium and surrounded by a muscle layer. Although these are non-secretory cavities they contain urine as a result of a passive filling from the adjacent collector system. The large majority of these lesions have less than 1 cm in diameter. Many are asymptomatic and are frequently found incidentally during elimination urography for other reasons. They rarely require treatment but may cause symptoms related to size or associated complications (infection or lithiasis). A number of years ago, definite treatment of complicated calyceal diverticulum was open surgery, but this has been defeated lately by less invasive techniques such as shock wave and percutaneous nephrolythotomy.

[Bladder leiomyosarcoma in a young man with a transplant. Report of a case].

Contribution of one case of a 24-year-old patient, with a renal graft, who was diagnosed with vesical leyomiosarcoma. Radical cystectomy with ureterosygmoidostomy was performed. The rarity of vesical sarcoma, both in normal population or among those undergoing transplantation, as well as the greater tendency of transplanted patients to suffer malignant neoplasia, are emphasised.

[Ureteroscopy with pseudoanalgesia in the treatment of ureteral lithiasis].

Presentation of the results obtained in 35 patients with ureteral lithiasis treated over a two-year interval by means of ureteroscopy with pseudoanalgesia at the Hospital Insular, with a 89% success rate. We conclude that in selected cases, the use of peg ureteroscopy or pneumatic lithotrite is a valid therapeutical option since it is well-tolerated and has the benefit of a short or null hospitalization.

[Wunderlich's syndrome as the first manifestation of a renal angiomyolipoma].

OBJECTIVES: We present a case of renal angiomyolipoma presenting as Wunderlich syndrome. METHODS: The clinical and radiological features of the spontaneous perirenal hematoma are analyzed. RESULTS: Because it is a benign tumor, treatment of renal angiomyolipoma is by conservative surgery; however, this is not always possible. CONCLUSIONS: In patients with renal angiomyolipoma, treatment by nephrectomy or conservative surgery will depend on the hemodynamic status of the patient.

[Urinary bilharziasis. Comments on 10 cases].

Urinary bilharziasis is a parasitic disease caused by Schistosome haematobium which is prevalent in several African and Middle East countries. The closeness of the Canary Islands to the African continent and a greater population mobility have allowed us to diagnose and treat ten patients, all of them natural of this region. This paper outlines the case-reports, and reviews this parasitic disease which seriously affects the urinary tract and which must be specifically contemplated both in emigrants and occasional visitors from endemic regions.

[Renal adenocarcinoma with multicystic pattern].

One growth pattern of renal carcinomas is the multicystic of multilocular cysts one, of which few cases have been published but which according to Hartman represent 15% of total cases. This variant of the renal tumour arouses great diagnostic and therapeutical uncertainties with multicystic kidney, biopsy after surgery being the test which provides true diagnosis. Presentation of two clinical cases and review of this condition.

[Enterocystoplasty in the treatment of interstitial cystitis].

OBJECTIVE: To evaluate supratrigonal cystectomy and enterocystoplasty in patients with interstitial cystitis. METHODS: We reviewed four women with interstitial cystitis with infructuos conservative treatment and performed supratrigonal cystectomy and enterocystoplasty. All the patients fulfilled the NHI criteria with increased voiding frequency by night (mean 7.3 times). In 3 cases urodynamic study was available. We used is the four patients ileon as segment for the enterocystoplasty. RESULTS: Mean postoperative follow up was 60 months. In all cases the suprapubic pain disappeared and night voiding frequency reduced (mean 2.2 times). We don't have mayor complications. One patient needs self catheterism 3 years after surgery. CONCLUSION: In patients with interstitial cystitis to be operated supratrigonal cystectomy and enterocystoplasty is the most effective method.

[A fibroepithelial myxoid polyp of the renal pelvis in a patient with horseshoe kidneys. Apropos a case].

Tumours of the renal pelvis are usually urothelial carcinomas. The benign tumors are extremely rare. Fibroepithelial polyps are the most common mesodermal tumors of the upper urinary tract. They are found most commonly in the ureter but several have been reported in the renal pelvis. Patients usually present with pain and less commonly hematuria. Grossly, these polypoid structures are smooth nodules or filiform projections varying is size from a few millimeters to several centimetres. Histologically, they consist of a thick fibrous stalk with numerous vascular channels covered by a layer of normal or hyperplastic transitional epithelium. The etiology of these tumors is unknown but congenital, obstruction, allergy and trauma have been implicated. Conservative treatment is recommended when the diagnosis is certain. To our knowledge, this is the first report of fibroepithelial polyp of the renal pelvis in a patient with horseshoe kidney.

[Transurethral resection of ureteral tumor].

A patient with a tumor in the right pelvic ureter is described herein. Following diagnosis by ureteroscopy, the patient underwent TUR utilizing a ureteroresectoscope. No short- or long-term complications were observed. The scant number of cases in the literature and the advantages afforded by this technique (noninvasive, short duration of hospital stay, etc.) prompted us to report this case.
