[Surgical wound infection in renal transplant recipients].

Between 1980 and 1991, 504 transplantations were performed in our hospital. All patients received pre-surgical therapy with antibiotics. The total incidence of surgical wound infection was 15 cases (3%). After reviewing all parameters that could have been involved in the development of these infections, it become apparent that diabetes mellitus, more than one transplant in the same patient, development of haematoma in the wound and presence of urinary fistulae were statistically significant (p < 0.05). On the other hand, the use of the different immunosuppressive regimes (azathioprin and cyclosporin) and acute tubular necrosis showed no statistical significance (p > 0.05); also, no relationship was found between infection and acute graft rejection.

[Duplex echography in acute scrotum. Diagnostic possibilities].

Acute scrotum is a frequent reason for consultation at the urological emergency service. The most common causes, apart from trauma, are acute orchiepididymitis, torsion of the hydatids of Morgagni and torsion of the spermatic cord. Apart from a detailed examination of patient history and a careful physical examination, few diagnostic techniques can be utilized. To date, only the Doppler ultrasound has proved useful in corroborating the suspicion of vascular involvement, although this technique is very limited. With the availability of the duplex ultrasound, the possibility of making the differential diagnosis in the acute scrotum is enhanced. This technique permits morphological and functional assessment and avoids unnecessary exploration surgery within the scrotum.

[Valves of the anterior urethra].

Despite the cases reported in the literature, anterior urethral valves continue to be an uncommon condition. The foregoing has to be considered when evaluating children with urinary obstruction or recurrent infections. A case of anterior urethral valves associated with segmental saccular dilatation of the urethra is described and the diagnostic methods are highlighted.

[Horseshoe kidney: its usefulness in transplantation].

The horseshoe kidney is useful as a graft and should be transplanted. The technical difficulties can be avoided by en bloc removal, perfusion in situ with Collins solution, and bench surgery during graft preparation.

[Metastatic tumors of the penis].

The authors present four cases of metastasic penis tumours, two of which followed a prostate carcinoma, one vesical carcinoma and the other a carcinoma of the excretory duct. They make a review of world literature on the subject and study the possible ways of dissemination as well as the clinical picture and differential diagnosis with other pathological processes of the male genital organ and they stress in particular the bad prognosis as the metastases appear at a very advanced stage of the primitive illness.

[Torsion of the hydatid of Morgagni].

The authors present 6 cases of torsion of Morgagni's hydatid treated in the Emergency Urology Department over a two-year period. They stress the importance of the clinical diagnosis, as well as the differential diagnosis with other "acute, testicular bag" processes, in particular with funicular torsion. Surgical treatment is the only way of overcoming the pain, confirming the diagnosis and preventing the risk of secondary, testicular atrophy.

[Use of the great epiploon in the treatment of idiopathic retroperitoneal fibrosis].

Immediately after ureterolysis in the treatment of idiopathic retroperitoneal fibrosis, we covered the ureter with a large epiploon, forming a sheath with omentum covering the entire ureter from the renal pelvis to the juxtavesical area of the same. This technique revitalizes the ischemic ureter resulting from ureterolysis and protects against the reinclusion of the ureter mobilized inside the sclerolipomatous mass.

[Perineal ectopic testis].

The authors present three cases of perineal, testicle ectopia, two of which were diagnosed and treated in the Urology Department of the "La Fe" Hospital. The other observation was diagnosed and treated by one of us privately. The treatment was surgical in all the cases and good results were obtained in them all. They discuss the etiopathogeny, clinical characteristics and the uselessness of hormone treatment.

[Post-transplantation renal rupture].

INTRODUCTION: Renal allograft rupture in the transplanted patient represents a usually early postoperatory complication threatening graft and patient survival. Urgent management is often required. MATERIAL AND METHODS: Renal transplanted patients which had rupture of the renal allograft have been reviewed retrospectively. Between February 1980 and June 1996 a total of 868 renal transplants were performed, and 21 (2.41%) suffered from allograft rupture. Diagnosis was based mainly on the symptoms, blood analysis to test hematocrit value, and ultrasounds. RESULTS: Men age of the patients was 34 years old (21-49), 15 (71.4%) males and 6 (28.6%) females. Evolution was as follow: 4 patients underwent extracapsular nephrectomy due to non-functioning kidney; in 16 patients the graft could be preserved using different methods of renal corsetage (lyophilized human dura was applied in 8 cases, fascia lata in one, fascia lata and lyophilized human dura in 3 cases, and polyglycolic acid mesh in other 4 patients); and finally one patient was managed conservatively. There was no intra and post-operatory mortality. Four patients died lately of other causes not related to renal transplantation. Other 4 patients underwent chronic rejection and fail of the renal function. Two of these four patients have already received their second graft. A total of 13 patients have a good renal function (61.9%). CONCLUSIONS: Early diagnosis of the renal allograft rupture must be the main objective in order to initiate as soon as possible therapeutic measures that firstly should be aimed to preserve the graft (medically or surgically). Nephrectomy must be reserved for renal allograft rupture secondary to venous thrombosis and other situations threatening life.
