Percutaneous renal artery embolisation of non-functioning renal allografts with clinical intolerance.

The aim of the study was to evaluate the efficacy and safety of percutaneous renal artery embolisation of non-functioning renal allografts in patients with graft intolerance syndrome (GIS). Transcatheter artery embolisation was performed in 30 kidney transplant recipients with GIS. The duration of graft function had been 60+/-45 months.

[Bilobular benign retroperitoneal schwannoma].

Objective: To describe an additional case of retroperitoneal schwannoma.

Methods: A case of retroperitoneal neoplasm in a 29-year-old woman is presented. The clinical and therapeutic aspects are discussed.

Loss of heterozygosity in renal and hepatic epithelial cystic cells from ADPKD1 patients.

Autosomal dominant polycystic kidney disease (ADPKD) is one of the commonest genetic diseases in man, affecting 1:1000 individuals in the Caucasian population. It is caused by mutations in the PKD1 or PKD2 genes. Recently, controversial data regarding the mutational mechanism underlying cyst initiation have been reported: genetic analyses have shown that second somatic mutations may lead to cyst formation (detected as microsatellite loss of heterozygosity, LOH, and point mutations), but immunohistochemical studies show strong immunoreactivity for polycystin in some cysts.

Usefulness of urinary nuclear matrix protein 22 (NMP22) as a marker for transitional cell carcinoma of the bladder.

Objectives: The purpose of this study was to evaluate an immunoassay for urinary nuclear matrix protein, NMP22, as a novel marker for urothelial cancer.

Patients And Methods: NMP22 values were determined for 71 patients and 21 healthy volunteers. Each subject provided a single (3 voids) urine sample for analysis at the time of entry into the study.

[Renopancreatic transplant. Urologic complications].

Objective: Retrospective study of urological complications in our series of reno-pancreatic transplants.

Material And Methods: Between February 1983 and May 1994 our group has conducted 93 RPT, 80 of which, mean age 36 +/- 6 years (24-54 years), are studied in this paper: 57 male and 23 female with an average time in dialysis of 20 +/- 15 months (0-84 months) and diabetes evolution of 21 +/- 5 years (11-37 years).

Results: Actuarial annual survival of patient, renal graft and pancreatic graft has been 85%, 79% and 74% respectively.

[Is there an age limit for cadaveric kidney donors currently?].

Objectives: The insufficient number of kidney transplants has gradually raised the age limit to the cadaver kidney donor. The use of grafts harvested from older donors has been debated due to the existing structural and functional changes that might influence renal function and long-term graft survival. The foregoing aspects are discussed herein.

Urodynamic evaluation in simultaneous insulin-dependent diabetes mellitus and end stage renal disease.

Purpose: We evaluated the urodynamic changes produced by insulin-dependent diabetes mellitus with end stage renal disease.

Materials And Methods: A urodynamic evaluation was performed on 51 young patients (mean age plus or minus standard deviation 35 +/- 6 years) with long-term diabetes mellitus (average 21 +/- 6 years) and end stage renal disease (86% on dialysis).

Results: The urodynamic study was abnormal in 84% of the patients.

[Congenital urethral diverticulum].

Presentation of two cases of congenital diverticula of the bulbar urethra. The objective of this paper is to discuss the etiopathogenic theories, sings and symptoms, current diagnostic methods and therapeutic indications, and to conclude that this type of diverticula do not present a florid symptomatology, endoscopy being the best diagnostic and therapeutic method. Finally, a review of the literature is made based on two clinical cases.

[Beneficial effect of oxygen-free radical blockers in experimental kidney transplantation in rats].

Unlabelled: The clinical potential of free radical (OFR) ablative therapy is dependent upon the proportion of the total injury caused by the reperfusion mechanism compared with the proportion resulting from ischemic injury itself. Prostaglandin cascade can both activate and be activated by OFR.

Aim: to investigate the influence of different periods of cold ischemis in renal tissue (cortex and medulla) -regarding superoxide dismutase (S.

Vesical tumors in patients under 25 years of age.

Behavior of transitional cell carcinoma of the bladder during the third decade of life remains a controversial subject. During the period 1980-1988, we treated 7 patients (4 male and 3 female), 25 years of age or less (mean age 19.3, range 14-25), with transitional cell carcinoma of the bladder.

Splenorenal arterial shunt in the treatment of renovascular hypertension. Approach by a lumbar-retroperitoneal incision.

In a period of 16 years, 29 consecutive patients were operated on for a splenorenal arterial shunt through a lumbotomy incision and a retroperitoneal approach. There were 18 males and 11 females with a medium age of 42 years. All cases had uncontrollable and severe hypertension for an average medium time of 48 months, 11 patients had variable degrees of renal insufficiency.

[Vascular complications of kidney transplant. Stenosis of the renal artery].

The present paper analyzes the incidence of vascular complications and their treatment, in a series of 500 consecutive Heterotopical Kidney Transplants (KT), performed in our Service between January 1978 and December 1988. There was a total of 14 (2.8%) complications of which 8 (1.

[Entero-urinary fistula. A study of 22 cases].

We performed a retrospective study on 22 patients with entero-urinary fistulas that had been diagnosed and treated at the Hospital Clinico i Provincial in Barcelona during the period spanning 1981-1988. Fistulas were classified according to the organs or parts with which they communicated. Among the important etiogenic conditions were diverticular disease of colon.
