Ureteral Stenosis and Fistula after Kidney Transplantation.

Introduction: Ureteral complications after kidney transplantation are frequent and may have a negative impact on morbidity and graft function. Treatment modalities include conservative, endourological, and surgical techniques, with variable outcomes. The purpose of this study was to report the incidence, characteristics, treatment, and outcomes of ureteral complications at our center.

[Late kidney transplant complications treatment.].

Objectives: Late kidney transplant complication might compromise graft durability, thus the need for early detection and treatment.

Material And Methods: A PubMed review including the following MeSH terms was included: kidney transplant¨, ¨complications¨, ¨vascular complications¨,¨transplant renal artery stenosis¨, ¨ureteral obstruction¨,¨urologic complications¨, ¨forgotten stent¨, ¨vesicoureteralreflux¨, ¨urinary lithiasis¨ e ¨incisional hernia¨. Metanalysis and systematic review in spanish and English were included from January 2015 till February 2021, as well as relevant selected manuscripts.

Iterative renal transplantation: our experience on third transplants.

Purpose: To report our experience on third kidney transplantation, analyzing the complications and graft survival rates as compared to previous transplants.

Methods: Retrospective study of third renal transplants performed at our center. Outcomes were compared with a cohort of first and second transplants.

Grade 3a Clavien grade complication following percutaneous nephrolithotomy. Related factors and review of the literature.

Objective: We review the literature about bleeding complications of percutaneous nephrolithotomy (PCNL) and the application of the modified Clavien system classification.

Methods: We present a 38 year old man who underwent left PCNL with acute severe hematuria during the immediate postoperatory time. We review the literature and analyze the usefulness of the modified Clavien system to grade perioperative complications.

[The treatment of varicocele in the infertile male II: results on fertility].

Objectives: To analyze the efficacy of varicocele treatment, either surgical or endovoscular radiological occlusion, on pregnancy rates of infertile couples in which the male had clinically. patent left varicocele, and to identify which factors are associated with the probability of obtaining pregnancy in such cases.

Methods: This study is part of a more ample one described in previous article: "The treatment of varicocele in the infertile male I: Results on semen quality".

[The treatment of varicocele in the infertile male I: results on semen quality].

Objectives: To evaluate the effect of interventionist treatment of varicocele, either open surgery or endovascular radiological occlusion, on seminal parameters, and to identify which factors are associated with their normalization.

Methods: Between 1975 and 2000, 631 patients with the diagnosis of idiopathic varicocele were evaluated in our hospital; 238 of them were part of an infertile couple. Among them, finally, 183 underwent studies; they complied with the following criteria: 1) Infertility for more than one year; 2) seminal parameters below normality following WHO criteria (1992); 3) absence of other pathologies or diseases which could explain male infertility; and 4) absence of evident causes of male infertility.

[Varicocele's radiological endovascular occlusion].

Objectives: To report our experience on percutaneous treatment of male varicocele over the last 15 years.

Methods: 690 patients with left varicocele underwent percutaneous occlusion of the spermatic vein. Embolization was undertaken using various types of materials; the most frequently used association was coils and sclerosing substances.

[The effect of seminal leukocytes on semen quality in subfertile males with and without varicocele].

Objectives: To compare the concentration of leukocytes and round cells in semen samples of subfertile males (SM), men with varicocele (VM), and fertile males (FM) to establish a possible relationship between leukocyte concentration, semen parameters (pH, concentration, mobility, spermatic morphology) and lipidic peroxidation of the spermatozoid.

Methods: We evaluated 298 semen samples from: 42 fertile males, 170 subfertile males, and 86 men with varicocele. Sperm tests were performed following WHO criteria.

[Radiological diagnosis: scrotal ultrasound and Doppler ultrasound in the diagnosis of male infertility].

Objectives: To review the ultrasound technique, normal anatomy, bibliography, as well as the most frequent scrotal ultrasound findings in infertile patients studied in our center over the last five years, with special emphasis in the diagnosis of varicocele and its follow-up after surgical treatment or embolization.

Methods: We reviewed a total of 439 male patients with the diagnosis of infertility referred to our vascular ultrasound section between 1998 and 2004, and 101 patients referred for ultrasound control after treatment of varicocele (endovascular or surgical).

Results: The most frequent diagnosis associated with infertility were left varicocele (146 patients, 33.
