AIM: The present study evaluated the effect of differences in the peak systolic velocity (PSV) and resistive index (RI) in the testicular artery (TA), capsular artery (CA), and intratesticular artery (ITA) after microscopic subinguinal varicocelectomy (MSV) on postoperative pain and semen parameters. PATIENTS AND METHODS: Scrotal color Doppler ultrasound (CDUS) measurements were made in 33 patients (age 18-31 years) prior to MSV and 3 and 6 months after MSV. Pain was recorded using a visual analog scale and sperm concentration was determined to analyze the predictive value of the CDUS parameters regarding surgical outcome...

The aim of the study was to analyze the treatment effect of transumbilical single-port laparoscopic varicocelectomy (TUSPLV) on recurrent varicocele (VC). In order to compare the surgical effects of TUSPLV to traditional retroperitoneal ligation of the internal spermatic vein, 64 patients with recurrent VC were enrolled and divided into the control group (n=30) and the observation group (n=34). Patients in the control group underwent surgery using traditional retroperitoneal ligation of the internal spermatic vein, while those in the observation group underwent surgery using TUSPLV...

Sperm DNA fragmentation (SDF) has been generally acknowledged as a valuable tool for male fertility evaluation. While its detrimental implications on sperm function were extensively investigated, little is known about the actual indications for performing SDF analysis. This review delivers practice based recommendations on commonly encountered scenarios in the clinic. An illustrative description of the different SDF measurement techniques is presented. SDF testing is recommended in patients with clinical varicocele and borderline to normal semen parameters as it can better select varicocelectomy candidates...

REVIEW
Patrick Whelan, Laurence Levine
Varicocele is most often surgically repaired due to male infertility, however, has recently been linked to low serum testosterone. This paper serves to review the current literature regarding varicocele and its subsequent repair on serum testosterone. Twenty-eight human studies were identified with fifteen showing improved serum testosterone after repair. The majority of the studies that demonstrated improvement had preoperative testosterone levels that were low or below normal. Additionally, multiple well-designed studies with control groups not undergoing surgical repair demonstrated significant difference between groups...

BACKGROUND/PURPOSE: The purpose of the study was to determine if testicular delivery during microsurgical subinguinal varicocelectomy (MSV) reduces varicocele recurrence rates in pediatric patients. Testicular delivery during MSV enables ligation of the gubernacular veins, which is thought to reduce the likelihood of varicocele recurrence. However, recent studies have suggested that testicular delivery during MSV does not offer any beneficial effect and, therefore, may be optional or unnecessary...

OBJECTIVES: To investigate the safety and efficacy of a novel approach of microscopic subinguinal varicocelectomy with a "pulling" strategy. METHODS: Fifty-two male patients with varicocele were enrolled in this study. Twenty-six patients underwent conventional microscopic subinguinal varicocelectomy, whereas the remaining 26 patients accepted our novel approach of treatment. In this method, with a subinguinal incision, we dissociated the spermatic cord from the external ring...

OBJECTIVE: The main difficulty in laparoscopic or robot-assisted surgery is the narrow visual field, restricted by the endoscope's access port. This restriction is coupled with the difficulty of handling the instruments, which is due not only to the access port but also to the loss of depth of field and perspective due to the lack of natural lighting. In this article, we describe a global vision system and report on our initial experience in a porcine model. MATERIAL AND METHODS: The global vision system consists of a series of intraabdominal devices, which increase the visual field and help recover perspective through the simulation of natural shadows...

BACKGROUND: Varicocele represents one of the most common surgically correctible urologic anomalies in adolescent males. The best procedure for the treatment of adolescent varicocele has not been established, but with recent advances in minimal access surgery, there have been many reports praising the safety and efficacy of laparoscopy and retroperitoneoscopy for the surgical correction of varicocele in adolescent. The aim of this review is to compare the results of Palomo's technique, with retroperitoneoscopic and transperitoneoscopic approaches in adolescent, analyzing recurrence, testicular growth and complications...

INTRODUCTION: Subinguinal microscopic ligation is the current standard of treatment of varicocele, and percutaneous embolization is a new alternative. We aimed to compare these procedures for reproductive and functional aspects. MATERIAL: A consecutive series of 76 patients with clinical varicocele, alteration of semen parameters and infertility, undergoing either procedure (microsurgery in 49 cases and embolization in 27 cases) was prospectively analyzed preoperatively and postoperatively (at 1, 3, 6, 9 and 12 months)...

PURPOSE: The main indications for adolescent varicocelectomy are testicular hypotrophy or pain. However, we have previously shown that both serial total testicular volume and volume differential are weakly associated with semen quality. The ultimate patient goal is paternity, but semen analysis is critical to appropriate management of varicocele. We hypothesize that varicocelectomy improves total motile count (TMC) among patients who only have abnormal semen analysis (SA) parameters, but not among those with potential hormonal dysfunction such as Klinefelter syndrome or cryptorchidism...

Objective: To investigate the expression of microRNA 210 (miR-210) in the epididymis of rats with varicocele and changes in miR-210 expression following high spermatic vein ligation, so as to explore the significance of the surgery in treating varicocele. Methods: A total of 21 male Sprague-Dawley (SD) rats aged 7 weeks were randomly divided into control group (n=7), experimental group (n=7), and surgical group (n=7). Varicocele model was established in both the experimental and surgical groups, while only vein isolation was performed in the control group...

OBJECTIVES: Microsurgical subinguinal varicocelectomy is one of the best treatment modalities for varicoceles related to male infertility and scrotal pain. However, the difficulty in identifying testicular arteries, which should be spared, is a limitation of this technique. To visualize and identify the testicular arteries in spermatic cord during the operation, we examined the efficacy of intraoperative indocyanine green angiography (ICGA), which is regularly used in microsurgical neurosurgery...

The aim of this study was to evaluate current practice patterns on diagnosis and management of pediatric varicoceles. Questionnaires of approaches to diagnosis and management of pediatric varicoceles were sent electronically to pediatric urologists. Of the 70 questionnaires e-mailed, 37 (53%) responded to the survey. 10 respondents (27%) chose to operate on varicoceles, whereas 9 (24%) chose to observe, and 18 (49%) chose to decide upon treatment depending on the clinical situation. The most important indication for varicocelectomy was a decrease in ipsilateral testicular size (n=29, 78%) followed by testicular or scrotal pain (n=4, 11%) and varicocele grade (n=4, 11%)...

REVIEW
Koji Chiba, Masato Fujisawa
Varicoceles are a major cause of impaired spermatogenesis and the most common correctable cause of male infertility. They are found in approximately 40% of men with primary infertility and 80% of men with secondary infertility, although they also occur in 12% of men with normal semen parameters. The presence of a varicocele does not always affect spermatogenesis, as it has been reported that only 20% of men with documented varicoceles suffer fertility problems. However, varicocele repair appears to have beneficial effects in men with impaired semen parameters and palpable varicoceles...

There is evidence to show that varicocele repair can improve conventional sperm parameters but the effects on sperm chromatin integrity have not been fully elucidated. We sought to examine the effects of varicocelectomy on sperm maturation, nuclear chromatin integrity and nuclear sulfhydryl groups. We conducted a prospective study of consecutive infertile men (n=29) that underwent a microsurgical sub-inguinal varicocelectomy for treatment of a clinically palpable varicocele and abnormal semen parameters. Six healthy sperm donors served as controls...
