[The therapeutic approach in vascular damage from pyelocaliceal endoscopic urology].

Six cases of vascular lesion associated with percutaneous removal of renal calculi are described. The lesions had been caused during percutaneous access or ultrasound fragmentation of the stone. Those that had resolved spontaneously have not been included. When vascular injury is suspected during the procedure, the appropriate measures must be taken to resolve the different complications, such as arteriovenous, arteriocaliceal or venocaliceal fistula. Since there is little reference to this subject in the Spanish literature, the experience described herein may be of interest to the urologist who has only recently begun to perform this technique.

[Endourologic treatment of tumors of the superior urothelium: results and clinical course].

Presentation of 31 patients with suspected diagnosis of upper urothelium tumour seen between 1986 and 1991. In agreement with our study protocol and the endourological treatment followed in this type of tumours, there were eight false positive, which were excluded. Five cases were treated by retrograde ureterorenoscopy while in the remaining 18 cases the anterograde percutaneous approach was used. A review of both the aspects of endoeurological treatment and the evolution of these patients during that period is included.

[Laparoscopic signs of testicular absence].

Unlike the other exploratory techniques (US, arteriography, phlebography, CT and MRI), laparoscopy constitutes the only reliable diagnostic method for absent testis, which has a high incidence in children with non palpable testes. The finding of the blind-ending spermatic veins and deferent duct confirms the diagnosis of absent testis.

[Efficacy and limitations of piezoelectric extracorporeal lithotripsy in kidneys with anatomical abnormalities].

We analyze the results achieved by extracorporeal piezoelectric lithotripsy (EPL) in 40 renal units with the following anatomic anomalies: solitary kidney (10), chronic pyelonephritis (8), medulospongiosis (6), caliceal diverticula (5), intrarenal cysts (5), pyeloureteric duplicity (3), megacaliosis (1), horseshoe kidney (1), and ureterocele (1). Adequate stone fragmentation was achieved in 80% of the patients with solitary kidney; 20% developed obstructive complications (1 patient with a 15 mm.-stone and 1 patient with obstruction of double-J catheter). At 6 months, stone remnants persist in 71.4% (5/7) after stone fragmentation in those cases with pyelonephrosis. The rates for fragmentation, elimination of remaining stone fragments, and disappearance of pain are 80%, 50% and 100% for diverticular caliceal calculi, and 67%, 50% and 100% for those in kidney with medulospongiosis. We can conclude that placement of a double-J catheter is useful before EPL in patients with solitary kidney and calculi greater than 10 mm. EPL is the first therapeutic approach in symptomatic lithiasis in caliceal diverticula or precaliceal cystic dilatation (medulospongiosis).

[The determination of prolactin levels in men suffering from impotence (author's transl)].

Basal prolactin, FSH, LH and testosterone levels were determined in 47 patients presenting with impotence. Clinical history, physical examination, general analysis and personality questionnaire were normal. In two patients taking medications (imipramine and dogmatil), prolactin levels were high. The other patients had normal hormone levels. The authors discuss the various mechanisms which play a role in the secretion of prolactin and the various means available to assess changes therein.

[Adult renal polycystosis as the causal entity of an intercostal hernia containing an intestinal loop: an unusual clinical case].

OBJECTIVE: To describe a case of adult renal polycystosis causing intercostal hernia with intestinal segment. To our knowledge, no such case has been previously reported in the literature. METHODS/RESULTS: Diagnosis was by abdominal CT. Treatment was by bilateral nephrectomy and surgical repair of the diaphragmatic and intercostal hernia. CONCLUSIONS: Surgery is indicated in adult renal polycystosis if kidney size causes gastrointestinal involvement and above all, if the lungs are compromised by the intercostal diaphragmatic hernia.
