OBJECTIVE To evaluate the effectiveness and limitations of antegrade sclerotherapy (AS) for the treatment of primary varicocele in childhood. PATIENTS AND METHODS From December 1996 to December 2004, 88 patients (mean age 13.3 years, range 9-18) with primary varicocele underwent AS (91 varicocele ablations in all). The indications for surgery were testicular pain (16 boys, 18%), a large varic...

Nonobstructive azoospermia (NOA) refers to repeated inability to detect sperm in the centrifuged pellet of semen due to primary testicular failure (1,2). NOA is not uncommon, affecting approximately 1% of all men and 10% of infertile men (3). Clinical varicocele has been implicated as a main cause of testicular dysfun...

Introduction: Varicocele is the most commonly observed and correctable cause of male factor infertility. The exact pathophysiology of varicocele is not known for certain. The purpose of our study was to analyze the effect of varicocele on the semen composition characteristics by semen analysis before and after varicocele ligation and also to assess the improvement in fertility status after vari...

BACKGROUND No reports have been published about age-related sperm malformations in varicocele patients. AIM To investigate the distribution of abnormal sperm characteristics in adolescents, adults and older men with varicocele. SETTING AND DESIGN Records of semen analysis of 143 men aged 14 to 53 years who had evident left-sided varicocele detected by physical examination and confirmed by d...

Varicocele is a major cause of male infertility, as it may impair spermatogenesis through several distinct physiopathological mechanisms. With the recent advances in biomolecular techniques and the development of novel sperm functional tests, it has been possible to better understand the mechanisms involved in testicular damage provoked by varicocele and, therefore, propose optimized ways to pr...

OBJECTIVE Analyze whether testicular histologic patterns from a group of azoospermic men with varicocele is predictive of treatment outcome after subinguinal microsurgical varicocele repair. MATERIALS AND METHODS Seventeen azoospermic men underwent bilateral open single testis biopsy and microsurgical subinguinal repair of clinical varicoceles. RESULTS Histopathology of testicular biopsies ...

PURPOSE To compare clinical characteristics and surgical results in adolescents and adults with varicocele. MATERIALS AND METHODS We retrospectively analyzed the characteristics of 93 patients, 34 adolescents (mean age, 14.4±2.1 years) and 59 adults (mean age, 30.4±12.4 years), who underwent surgical repair of varicocele between 2006 and 2009. Median follow-up time in all patients was 18.7 mo...

The clinical manifestation of renal vein thrombosis varies with the speed and degree of venous occlusion. Such patients may be asymptomatic, have minor nonspecific symptoms such as nausea or weakness, or have more specific symptoms such as upper abdominal pain, flank pain, or hematuria. Acute scrotal pain is a very uncommon clinical expression of renal vein thrombosis. Here, we report a case of...

The treatment of varicoceles in adolescents is highly controversial. In contrast to adults with varicocele, fertility status is not yet known and it is not generally feasible to obtain a semen analysis in adolescents in order to guide treatment. Hence, the principal indication for surgery in teenagers is hypotrophy/atrophy of the left testis associated with a varicocele. Recent evidence in adul...

BACKGROUND Varicocele, one of the most common causes of sperm abnormalities in men, is the dilation of the testicular vein (the pampiniform venous plexus) by more than 2 mm. Ultrasonography is the primary imaging procedure for varicocele diagnosis. The venous diameter is evaluated using B-mode sonography, and venous reflux is assessed using color Doppler sonography. OBJECTIVES In this study, ...
