[Acute focal bacterial nephritis. Pathology mimicking renal masses]. / Nefritis aguda bacteriana focal. Patología mimetizante de masas renales.

Focal acute bacterial nephritis is an uncommon form of renal acute infection with a clinical presentation that, although similar to other acute infections of the renal parenchyma, must be taken into account in order to reach a correct differential diagnosis with other processes which have very similar radiological images but highly different management approaches, such as the renal carcinoma. This paper present one case in which the sings and symptoms were crucial to establish the diagnosis.

[Unilateral ureteral hernia. Report of a case]. / Hernia ureteral unilateral. A propósito de un caso.

Hernia of the ureter is an uncommon condition and may classified into two types in relation to the peritoneum: extraperitoneal (without hernial sac) and paraperitoneal (with permeable peritoneum and redundant sac). This condition is generally asymptomatic and may be detected incidentally during urography or herniorrhaphy. We report on a case that had been detected during radiologic control evaluation of a left percutaneous nephrostomy prior to treatment with ESWL of a calculus in the ipsilateral lumbar ureter.

[An arteriovenous fistula as a complication of percutaneous nephrostomy]. / Fístula arteriovenosa como complicación de la nefrostomía percutánea.

Percutaneous nephrostomy has emerged as a substitute for surgical nephrostomy. The complication rate is low, hematuria being one of the most common. Treatment should be conservative while possible since the clot plays an important role in the tamponade of hemorrhage. Arteriovenous fistulas following percutaneous nephrostomy are rare. Diagnosis is by arteriography and treatment is by selective embolization.

[Local anesthesia in the surgical management of hydrocele and cysts of the spermatic cord]. / La anestesia local en el tratamiento quirúrgico del hidrocele y quiste de cordón espermático.

Traditional management of vaginal fluid collections has always been surgery. The benignancy of this disease does not correspond with the morbidity caused by the anaesthetic techniques used. Over the last few years, sclerotherapy has become increasingly attractive as an alternative to hydrocelectomy. Indications are, nonetheless, restricted, presenting a relapse rate which varies according to the substance used and the operating team. The study proposes the use of local anaesthetics for the surgery of vaginal fluid collections so as to minimize the immediate postoperative period and thus the hospital stay. Between May and October 1991, 55 patients, 49 with hydrocele (4 bilateral) and 6 with sperm cord cyst, were treated in our Unit. Patients were monitored in the theatre (EKG, blood pressure and oximeter) to supervise their life constants, and 2% Mepivacaine (10-20 cc) was infiltrated into the sperm cord and the area of scrotal wall to be cut. Surgical techniques range from dissection to scission of the bag until partial eversion, requiring the use of reabsorbable suture and a careful haemostasis to avoid drainage. Anaesthetics tolerance has been highly satisfactory in 52 patients (94%), good in one patient (2%) and unsatisfactory in two cases (4%). Recorded complications include: severe bradycardia and hypotension in one case (2%), persistent right renoureteral pain in one case (2%), scrotal haematoma in 5 cases (9%) and suture dehiscence in another patient (2%). It is concluded that surgical management of vaginal collection with local anaesthetics is feasible, and reduces the immediate postoperative period also avoiding morbidity derived from a more aggressive anaesthetic technique.

[Dermatomyositis as paraneoplastic syndrome of bladder tumor]. / Dermatomiositis como síndrome paraneoplásico de tumor vesical.

The dermatomyositis is a connective tissue disease characterized by changes affecting both the skin and the muscle, appearing most frequently around the fifth and sixth decades and which association to a vesical tumour is very rare. This paper contributes one case of paraneoplastic dermatomyositis associated to infiltrant vesical tumour, presenting erythematous damage in face, nape of the neck and upper thorax, as well as periorbital heliotrope erythema and fingernails base and sides telangiectasia, all of which are typical signs of dermatomyositis.
