Abstract
BACKGROUND Management of the adolescent varicocele focuses on optimizing fertility potential, but to date there is limited data on the success of varicocelectomy on optimizing semen parameters for individual adolescent patients. We reviewed our database of over 1600 adolescent varicocele patients to find those with pre- and postoperative semen analyses to determine the impact of varicocele correction. METHODS 15 Tanner stage V patients with unilateral clinically apparent left-sided with pre- and postoperative semen analyses were identified. Mixed models were used to compare semen parameters pre- and post-varicocelectomy in patients with successful management. RESULTS Complete elimination of the varicocele was achieved in 12/15 (80%) patients. Three patients had persistent varicocele (with down-grading in two) and declined further intervention. Median time between pre- and postoperative semen analyses was 24.2 months. For those with successful varicocele correction, total motile sperm count (TMSC) improved in all but one (Figure 1), with an average increase of 44.0 million (95% CI: 18.7-69.3) in post-varicocelectomy analyses compared to pre-varicocelectomy (p = 0.0016). Mean percent improvement was 649.2%. It went from abnormal to normal (≥20 million/cc) in 55.6% (5/9). For the three patients with persistent varicocele, one had improved TMSC from abnormal to normal range, one had worsening within normal range, and one had effectively no change. CONCLUSION Successful correction of adolescent varicocele may improve TMSC. In over half of our institution's cases, an abnormal value normalized. Surgical intervention may be considered for adolescent varicoceles associated with abnormal semen parameters. LEVELS OF EVIDENCE Level III. TYPE OF STUDY Treatment study.

Embolization in Pediatric Patients: A Comprehensive Review of Indications, Procedures, and Clinical Outcomes. J Clin Med 2022; 11:jcm11226626. [PMID: 36431102 PMCID: PMC9696500 DOI: 10.3390/jcm11226626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 10/30/2022] [Accepted: 11/02/2022] [Indexed: 11/10/2022] Open
Abstract
Embolization in pediatric patients encompasses a large spectrum of indications, ranging from the elective treatment of congenital diseases of the cardiovascular system to the urgent management of acute hemorrhagic conditions. In particular, the endovascular treatment of central and peripheral vascular malformations and hypervascular tumors represents a wide chapter for both congenital and acquired situations. Thanks to the progressive availability of low-profile endovascular devices and new embolic materials, the mini-invasive approach has gradually overtaken surgery. In this review, the main embolization procedures will be illustrated and discussed, with a focus on clinical indications and expected outcomes. The most recent mini-invasive techniques will be described, with hints on the cutting-edge devices and embolic materials.

Abstract
A varicocele is an abnormal dilation of the pampiniform plexus of veins in the scrotum which begins at puberty in approximately 15% of males. Although common in the general population and often asymptomatic, varicoceles are associated with gonadal dysfunction including testicular atrophy, infertility, and hypogonadism in a subset of men diagnosed later in life. Because of the high prevalence and uncertain pathogenesis, definitive management guidelines for varicoceles diagnosed in the pediatric and adolescent population remain poorly defined. The varicocele is the most common etiology of male factor infertility, and treatment in the pediatric and adolescent population may improve semen quality and improve fecundity in adulthood. Evaluation of the pediatric and adolescent varicocele should include history, physical exam, and measurement of testicular volume with orchidometer or ultrasound. Testicular volume differentials and peak retrograde flow on Doppler ultrasonography are important factors in risk stratification of the pediatric varicocele population. Semen analysis and reproductive endocrine assessment should also be considered as part of the workup for adolescent patients. A variety of treatment approaches exist for varicocele, and while the microsurgical subinguinal approach is the gold standard for the adult population, it has yet to be confirmed as superior for the adolescent population. Referral to an andrologist for the adolescent patient with varicocele should be considered in equivocal cases. While active treatment of varicocele in the pediatric and adolescent population is controversial, it is clear that some untreated patients will suffer symptoms later in life, while overtreatment remains a concern for this large, vulnerable population. Therefore, surveillance strategies and improved accuracy in diagnosis of clinically important pediatric varicoceles prompting treatment are needed in the future.

Abstract
Varicocele is characterized by elongation, dilatation, and tortuosity of the veins draining the testis and its covers, causing circulatory reflux along the inner spermatic vein [ 1 ]. Varicocele results in progressive testicular lesions and, if untreated, can lead to testicular atrophy [ 2 ]. Varicocele is considered the most frequently identified cause of male infertility [ 3 ]. The mechanisms involved in varicocele formation are not well known and probably are multiple, differing from one patient to another.

Abstract
Background Varicocele is a condition characterized by dilated, tortuous veins within the pampiniform venous plexus of the scrotal sac. Presence of varicocele is associated with an increased risk of alteration of semen parameters. The objective of this study was to compare the current standard in varicocele treatment procedures: sub-inguinal microscopic ligation to percutaneous embolization in terms of semen parameters improvement, fertility, and morbidity at the university hospital of Toulouse (France). Seventy six patients with clinical varicocele, alteration of semen parameters and infertility, underwent either procedure (microsurgery in 49 case performed by a single surgeon and embolization in 27 cases) and were prospectively analyzed. Outcome measures were: semen parameters, spontaneous pregnancies, pain, side effects, recovery time and overall satisfaction. All patients were contacted in January 2015 in order to determine reproductive events. Results Preoperatively, there was no difference in clinical and biological items between the two groups. Postoperatively, on the overall population, there was a significant improvement of sperm concentration at 3, 6, 9 and 12 months (p = <0.001, <0.001, 0.012, 0.018) and sperm motility at 6 months (p = 0.002). The sperm concentration was higher at 6 months in the percutaneous embolization group (13.42, vs. 8.1×106/ml; p = 0.043). With a median follow-up of 4 years, 27 pregnancies occurred (spontaneous pregnancy rate of 35.5%). There was no significant difference between procedures on the sperm quality, pregnancy rate, and the overall satisfaction. Patients undergoing percutaneous embolization reported a faster recovery time (p = 0.002) and less postoperative pain (p = 0.007). Conclusion Our study shows that percutaneous embolization seems to be an equivalent alternative to sub-inguinal microscopic ligation in term of sperm quality improvement, pregnancy rate, and overall satisfaction with a slight advantage on post-operative morbidity.

Abstract
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). Outcome measures were: semen parameters, pregnancies, pain, side effects, recovery time and overall satisfaction. Subsequently, all patients were contacted by telephone in January 2015 (with a median delay of 4 years after the procedure) in order to determine reproductive events. RESULTS Preoperatively, both groups were identical for clinical and biological items. We observed an improvement of sperm concentration at 3, 6, 9 and 12 months (P<0.001, <0.001, 0.012, 0.018, respectively) and sperm motility at 6 months (P=0.002). The sperm concentration was higher at 6 months in PE group (P=0.043). With a median follow-up of 4 years after the procedure, 27 pregnancies occurred (spontaneous pregnancy rate of 32%). There was no difference between procedures on the sperm quality, pregnancy rate and the overall satisfaction. Patients undergoing percutaneous embolization reported a faster recovery time (P=0.002) and less postoperative pain (P=0.007). CONCLUSION Both procedures give equivalent results regarding sperm quality, pregnancy rate and satisfaction even though recovery seems faster and postoperative pain seems lower after percutaneous embolization.

Abstract
Adolescent varicocele is associated with ipsilateral testicular hypotrophy and the concern for future infertility. A testicular size discrepancy greater than 15-20 % between left and right testicle is an indication for treatment to allow catch-up growth in the hope of preventing a future decline in fertility. Some authors advocate for a period of watchful waiting, as normal testicular growth may occur asymmetrically. We review the current literature to highlight some controversies and challenges in management.

Abstract
OBJECTIVE To evaluate the seminal, hormonal, and spontaneous pregnancy outcome after percutaneous embolization of the internal spermatic vein in infertile men with left-sided subclinical varicocele and one or more abnormal semen parameters. METHODS A total of 218 patients underwent percutaneous embolization, and 119 patients were included as the observation group. All patients were followed up prospectively for 39.4 ± 6.5 months. Semen parameters and hormonal levels were evaluated before any procedure and 6 months after. RESULTS Significant improvement in the mean sperm concentration, total motility, and lower follicle-stimulating hormone levels was noted in those who underwent varicocele embolization as compared with those not treated. After 39.4 ± 6.5 months, pregnancy rates were 46.3% for the treated group and 11.8% for the control group (P = .011). CONCLUSION In infertile men, small varicoceles, even subclinical ones, should be identified and treated.

Abstract
OBJECTIVE This is a retrospective study to compare duplex scan results of laparoscopic Palomo's technique through retroperitoneal and transperitoneal approach for varicocelectomy in children. We statistically analyzed recurrence, testicular volume growth and complications. PATIENTS AND METHODS Surgical intervention was performed utilizing transperitoneoscopic (group A) or retroperitoneoscopic access (group B). Duplex scan control was performed after 12 months (T1), after 2 years (T2) and the last one at 18 years old in most patients. Statistical analysis was performed using the t-test for parametric data. Differences in proportions were evaluated using χ2 or Fisher's exact test. RESULTS We treated 120 children (age range 10-17 years) who presented an asymptomatic IV grade of reflux, Coolsaet 1, associated with a left testicular hypotrophy in 36.6% of the cases (44 patients). No post-operative complications were verified. Duplex scan exam showed an increase of left testicular growth in both groups, with complete hypotrophy disappear in patients in both groups after 24 months. Hydrocele, diagnosed clinically and confirmed with duplex scan, was the most frequent post-operative complication (22/120 cases; 18.3%). CONCLUSIONS This study showed the importance of duplex scan at all steps of this vascular pathology in children, and that there is no significantly difference in results between the two surgical techniques except for hydrocele in transperitoneoscopic access.

Abstract
Varicocele is the most common cause of male infertility and is generally correctable or at least improvable by various surgical and radiologic techniques. Therefore, it seems simple and reasonable that varicocele should be treated in infertile men with varicocele. However, the role of varicocele repair for the treatment of subfertile men has been questioned during the past decades. Although varicocele repair can induce improvement of semen quality, the obvious benefit of spontaneous pregnancy has not been shown through several meta-analyses. Recently, a well-designed randomized clinical trial was introduced, and, subsequently, a novel meta-analysis was published. The results of these studies advocate that varicocele repair be regarded as a standard treatment modality in infertile men with clinical varicocele and abnormal semen parameters, which is also supported by current clinical guidelines. Microsurgical varicocelectomy has been regarded as the gold standard compared to other surgical techniques and radiological management in terms of the recurrence rate and the pregnancy rate. However, none of the methods has been proven through well-designed clinical trials to be superior to the others in the ability to improve fertility. Accordingly, high-quality data from well-designed studies are needed to resolve unanswered questions and update current knowledge. Upcoming trials should be designed to define the best technique and also to define how to select the best candidates who will benefit from varicocele repair.

Abstract
This study was conducted to introduce a simple modification that can facilitate microsurgical subinguinal varicocelectomy (MSV) especially for surgeons inexperienced in microsurgical technique. A single surgeon performed microsurgical intermediate subinguinal varicocelectomy (MISV) on 52 patients with 61 cases between September 2010 and August 2012. Patient age, varicocele grade, operation time, intraoperative findings, postoperative complications, and 3-month follow-up results were analyzed. Patient mean age was 28 years (range, 15-69 years), and there were 9 bilateral cases. The mean operative time was 51 minutes (range, 34-109 minutes). We compared the first 31 cases to the second 30 cases, to assess investigator experience on operating times. The mean number of ligated veins was 5 (range, 3-10) in internal spermatic vein, 1 (range, 0-4) in external spermatic vein, and 1 (range, 0-3) in gubernacular vein. In 28 patients, the average postoperative sperm concentration at the 3-month follow-up was significantly higher than the preoperative sperm concentration (28.5±18.2×10(6)/mL versus 10.5±23.0×10(6)/mL; P=0.003). Mean motility improved after MSIV (65.7%±18.2% versus 47.2%±21.7%; P=0.004). In conclusion, MISV appears comparable with MSV in terms of the high success rate, low complication rate, and low postoperative pain; and it can be easily accomplished by inexperienced surgeons.

Abstract
Varicocele is a common pathology of the testis frequently associated with infertility. For its management, a fine morphological study of the testis, both macroscopically and microscopically, and an accurate choice of surgical procedure are mandatory. The present review focuses its attention on the anatomic substrates of adolescent varicocele and its pathophysiologic modifications. The comprehensive assessment of all the reported alterations should be considered by the clinician before deciding the type of treatment and the timing.

Materials and Methods The PubMed and Embase online databases were searched for studies released before December 2012. References were manually reviewed, and two researchers independently extracted the data. To assess the quality of the studies, the Cochrane risk of bias as a quality assessment tool for randomized controlled trials was applied. Results Seven randomized clinical trials were included in our meta-analyses, all of which compared pregnancy outcomes between surgical varicocele repair and control. There were differences in enrollment criteria among the studies. Four studies included patients with clinical varicocele, but three studies enrolled patients with subclinical varicocele. Meanwhile, four trials enrolled patients with impaired semen quality only, but the other three trials did not. In a meta-analysis of all seven trials, a forest plot using the random-effects model showed an odds ratio (OR) of 1.90 (95% confidence interval [CI], 0.77 to 4.66; p=0.1621). However, for subanalysis of three studies that included patients with clinical varicocele and abnormal semen parameters, the fixed-effects pooled OR was significant (OR, 4.15; 95% CI, 2.31 to 7.45; p<0.001), favoring varicocelectomy. Conclusions Varicocelectomy for male subfertility is proven effective in men with clinical varicocele and impaired semen quality. Therefore, surgical repair should be offered as the first-line treatment of clinical varicocele in subfertile men.

Abstract
OBJECTIVE To determine whether local anesthesia (LA) is an acceptable alternative to spinal anesthesia (SA) for varicocelectomy. METHODS A total of 60 men with varicocele were included in the present study. The evaluation of pain during and after surgery was determined using the visual analog scale. The secondary outcome measures of the present study were the interval to the first postoperative analgesic requirement, total analgesic consumption, and the incidence of side effects. RESULTS The mean postoperative visual analog scale score was 2.56 ± 1.85 for the SA group and 2.77 ± 1.94 for the LA group (P = .659). Patients in the SA group experienced significantly less pain during surgery than those in the LA group (P = .017). However, the pain scores between the 2 groups did not differ significantly at 2, 4, 6, 8, 12, or 24 hours after surgery. In addition, a positive correlation was found between the duration of symptoms and the visual analog scale score at 24 hours postoperatively. The mean dosage of injected diclofenac was 46.5 ± 23.3 mg and 32 ± 28.15 mg in the SA and LA groups, respectively (P = .018). The SA group developed more postoperative complications, such as urinary retention, postspinal backache, headache, hypotension, and delayed mobilization, in the postoperative period. CONCLUSION LA is an effective, reliable, reproducible, simple, and safe alternative anesthetic method for subinguinal varicocelectomy.

Abstract
During adolescence, the risk of developing a varicocele increases. Prevalence is less than 1% in boys aged younger than 10 years, but approaches that of the general adult population (about 15%) during puberty. For adolescent males with varicoceles, surgical risk factors have not yet been clearly delineated and clinical severity correlates poorly with prognosis. Fortunately, the widespread use of Doppler ultrasonography is transforming the diagnostic work-up for this demographic. A continuous reflux detected by color Doppler ultrasound (CDUS) is thought to have a negative prognostic value and evidence suggests that a peak retrograde flow above 38 cm per second is a powerful predictor of lack of spontaneous improvement in adolescent patients with ≥ 20% asymmetry between testes. CDUS also enables the detection of varicocele resulting from reflux in the deferential vein adjunctive to a refluxing internal spermatic vein; a causality that accounts for approximately 15% of cases. In addition to a diagnostic role, hemodynamic parameters can be used to predict the risk of persistence or worsening asymmetry. Although further studies are necessary to validate single parameters, it seems that the more severe the reflux, the greater the likelihood that the patient will develop testicular asymmetry.

Abstract
BACKGROUND In this study we present our experience using minilaparoscopic intracorporeal knot tying to ligate internal spermatic veins (ISV) while sparing the spermatic artery and lymphatics. METHODS Minilaparoscopic varicocelectomies were performed in 87 patients between January 2004 and January 2009. All varicoceles were detected clinically according to the World Health Organization (WHO) classification and confirmed by scrotal color Doppler ultrasonography. The surgical indications were scrotal symptoms in 71, infertility in 16, and both conditions in 2. Three 3.5 mm minilaparoscopic ports were used for the operation. The ISVs were dissected and then ligated with intracorporeal knot-tying. The testicular artery and lymphatic vessels were carefully preserved to minimize procedure-related complications. RESULTS Unilateral laparoscopic varicocelectomy was performed in 21 (24.2%) patients and bilateral in 66 (75.8%). Mean operative time was 71.1 ± 29.2 and 46.8 ± 12.6 min for bilateral and unilateral varicocelectomies, respectively. All patients were discharged within 24 h after surgery. Neither immediate major nor late procedure-related complications were noted. Of the 71 patients with scrotal symptoms, the symptoms completely subsided in 55 (77.5%) and partially subsided in 10 (14.1%). Only one (1.2%) recurrent varicocele was detected within a mean follow-up of 21 months (range = 3-42). Neither hydrocele formation nor testicular atrophy was found during the follow-up period. CONCLUSION Our 5-year experience revealed that minilaparoscopic varicocelectomy with sparing of artery and lymphatic vessels could safely and effectively ligate all spermatic veins and preserve spermatic arteries and lymphatic channels without leading to a high varicocele persistence or recurrence.

Abstract
OBJECTIVE We carried out a nationwide epidemiological study to evaluate the prevalence and effect of varicoceles on testicular volume in South Korean adolescents. We also investigated the correlation between varicoceles and body mass index (BMI). METHODS In this prospective study, physical examinations were carried out to assess the presence and severity of varicoceles in middle school boys from six regions of South Korea. Testicular volume, height and weight of all boys were measured. The prevalence of varicoceles was assessed. The associations between age, testicular volume, BMI, and the presence and severity of varicoceles were examined. RESULTS A total of 1938 boys with a mean age of 14.1 years (range 13-16 years) were screened. A varicocele was found on the left side in 295 (15.2%) boys and on the right side in 8 (0.4%) boys. Bilateral varicoceles were found in 17 (0.9%) individuals. Of the subjects with a left varicocele, 151 (51.2%), 80 (27.1%) and 64 (25.1%) boys had a grade 1, 2 or 3 varicocele, respectively. The prevalence of varicoceles did not increase with age. The proportion of boys with testicular size discrepancies increased with the severity of the varicocele. After adjusting for age, BMI had a negative correlation with the presence of varicoceles. CONCLUSIONS The prevalence of varicoceles in South Korean middle school boys is 16.5%. The presence of varicoceles seems to have a negative effect on testicular growth. BMI has a significant inverse relationship with the occurrence of varicoceles.

Abstract
The aim of this study was to determine the correlation of ultrasonographic estimates of testicular volume with true testicular volume and to compare the accuracy and precision of the three most commonly utilized formulas. A total of 15 patients underwent high-resolution ultrasonography (US) analysis for testicular volume before orchiectomy. Testicular volume was calculated using three common formulas: (1) length (L) x width (W) x height (H) x 0.52; (2) the empirical formula of Lambert: L x W x H x 0.71; and (3) L x W2 x 0.52. The actual volume of each removed testis was estimated directly by a water displacement method. Thus, four volume measurements were obtained for each of the 30 testes. The obtained data were analyzed by paired t-test and linear regression analysis. All three US formula measurements significantly underestimated the true testicular volume. The largest mean biases were observed with US formula 1, which underestimated the true volume by 3.3 mL (31%). US formula 2 had a smaller mean difference from the true volume, with an underestimation of only 0.6 mL (6%). Regression analysis showed that formulas 1 and 2 had better R2 values than formula 3. However, all three US formulas displayed a strong linear relationship with the true volume (R2= 0.872-0.977; P < 0.001). Among the commonly used US formulas, the empirical formula of Lambert (L x W x H x 0.71) provided better accuracy than the other two formulas evaluated, and better precision than formula 3. Therefore, the formula of Lambert is the optimal choice in clinical practice.

Abstract
The development of testicular hypotrophy (or testicular growth arrest) in pediatric patients with varicocele is the first indication for surgery. The aim of this study is to identify the correlation between grade of varicocele, grade of vein reflux and testicular growth arrest. Between 2000 and 2001, we recruited 226 patients affected by varicocele without testicular hypotrophy and with grades 2-3 spermatic vein reflux observed during Doppler velocimetry. Medical examinations carried out every 6 months allowed the assessment of varicocele grade, testicular volume, and grade of vein reflux. Other parameters considered in the study were: mean time of grade deterioration, mean time to onset of testicular growth arrest and the relationship between varicocele grade and testicular growth arrest. Deterioration of the condition was experienced in 92 patients (40%) in which 60 patients showed higher varicocele grades without testicular growth arrest, while 32 patients developed testicular growth arrest. There was a statistically significant relationship between testicular growth arrest and varicocele grades (grade 2 and 3) and between grade of reflux and testicular growth arrest. Although it is not possible to determine which patients will develop testicular growth arrest, the assessment of vein reflux allows the identification of those subjects who may potentially develop such a condition.

Abstract
PURPOSE To report the results of treatment of adolescent patients with varicocele with use of 3% sodium tetradecyl sulfate foam (STS) in combination with pushable fibered coils. MATERIALS AND METHODS From September 2004 to September 2006, 16 adolescent patients (age 12-19 y) with symptomatic varicocele, testicular atrophy, or surgical recurrence underwent embolization with STS foam and coils. The left internal spermatic vein (ISV) was coaxially catheterized from the right femoral vein. Three percent STS foam was placed distally in the ISV during compression so minimal foam entered the pampiniform plexus. A second nest of coils was placed in the ISV at a position over the sacroiliac (SI) joint that occluded most of the parallel collateral vessels. Coils were not placed above the SI joint in most instances. Additional foam was injected in the ISV at the upper level of the SI joint. The upper ISV was left unoccluded. Our standard follow-up consisting of ultrasound and/or physical examination after varicocele occlusion was performed 2-12 months after the procedure. RESULTS All occlusions were technically successful, and 15 of 16 patients (94%) exhibited proven disappearance of the varicocele. All patients were asymptomatic except one who had pain despite disappearance of the varicocele. One patient with a bleeding disorder had 48 hours of scrotal discomfort as a result of pampiniform phlebitis caused by the deliberate passage of foam into the pampiniform plexus. CONCLUSIONS The use of 3% STS foam in combination with pushable fibered coils is a safe and effective sclerosing procedure for adolescent subjects with varicocele.

Abstract
Treatment of pediatric patients with varicocele is based on the desire to prevent testicular dysfunction and possible infertility that may become irreversible in adults. The authors reviewed their experience with retrograde percutaneous sclerotherapy (RPS) via a trans-femoral approach to assess its results in children. A retrospective study was conducted, including all the children admitted between 2000 and 2004 who underwent RPS with at least 24 months follow-up (FU). The indication for treatment was grade II and III varicocele (Dubin-Amelar classification), confirmed by Doppler US. Three per cent sodium tetradecyl sulfate was the sclerosing agent. FU included Doppler US 1 month after the procedure and then yearly for at least 2 years. Eighty-six children (mean age 13.8 years) underwent phlebography and, when feasible, RPS. Varicocele was grade II in 49 cases and grade III in 37. RPS was feasible in 72 (84%) children because of unfavourable anatomic features of the left spermatic vein. RPS was successful in 66 (92%) out of 72 treated children. Median FU was 29 months. During FU, five (8%) patients relapsed. RPS of varicocele is a simple and effective treatment. A minimum of 2 years FU is recommended, as a few cured cases may relapse during this period.

Abstract
OBJECTIVES To determine the accuracy of orchidometry and ultrasonography for measuring the testicular volume by comparing the resultant measurements with the actual testicular volume in humans. METHODS The testicular volume of 40 testes from 20 patients with prostate cancer (mean age +/- SD 74.5 +/- 7.5 years) was measured using the Prader orchidometer and ultrasonography before therapeutic bilateral orchiectomy. The ultrasound measurements of testicular volume were calculated using three formulas: length (L) x width (W) x height (H) x 0.52, L x W2 x 0.52, and L x W x H x 0.71. The actual testicular volumes were determined by water displacement of the surgical specimen. RESULTS The mean actual testicular volume of the 40 testes was 9.3 cm3 (range 2.5 to 23.0). A strong correlation was found between the testicular volume calculated by the three ultrasound formulas and the actual volume (r = 0.910 to 0.965, P <0.0001) and was stronger than the correlation with the Prader orchidometer (r = 0.818, P <0.0001). The smallest mean difference from the actual testicular volume was observed with the formula L x W x H x 0.71, which overestimated the actual volume by 0.80 cm3 (7.42%). The measurements using the Prader orchidometer correlated with the actual testicular volume and with the testicular volume calculated using the three ultrasound formulas (r = 0.801 to 0.816, P <0.0001). However, the orchidometer measurements had the largest mean difference from the actual testicular volume (6.68 cm3, 81.7%). CONCLUSIONS The results of this study have shown that measuring the testicular volume by ultrasonography is more accurate than by the Prader orchidometer, and the formula L x W x H x 0.71 was the most accurate for calculating the testicular volume.

Abstract
OBJECTIVES To compare the accuracy of testicular volume measurements with the Prader orchidometer versus ultrasonography. METHODS The volume of 938 testes in 469 men with infertility (mean age 35.8 years) was measured using a Prader orchidometer and by ultrasonography. The ultrasound testicular volumes were calculated using the formula length x width x height x 0.71. To compare any differences between the methods according to testicular size, the patients were divided into six groups according to the ultrasound-determined volume: less than 5, 5 to 10, 10 to 15, 15 to 20, 20 to 25, and 25 cm3 or more. RESULTS The mean volume by orchidometry and ultrasonography was 18.7 and 13.7 cm3 for the right testis and 18.0 and 12.5 cm3 for the left, respectively, and was significantly overestimated by orchidometry (P <0.0001; by 5.1 cm3 on the right and 5.5 cm3 on the left). The largest differences between methods were observed for volumes of 10 to 15 cm3 on the right and 5 to 10 cm3 on the left. The difference between the methods decreased as the ultrasound-determined volume increased (r = 0.636 on the right; r = 0.598 on the left testis). Nonetheless, the Prader orchidometric measurements showed a strong correlation with the ultrasound measurements (r = 0.707 on the right; r = 0.746 on the left). CONCLUSIONS The testicular volume estimated by Prader orchidometry correlated closely with the measurements by ultrasonography. However, the orchidometer overestimated the testicular volume, especially in small testes.

Abstract
OBJECTIVES To compare the intraoperative results of inguinal versus subinguinal varicocelectomy using magnifying loupe, in terms of vein ligation and arterial preservation, recurrence rate, and patient tolerability. METHODS Ninety-nine patients were randomized to undergo a varicocele repair with an inguinal or a subinguinal approach under local anesthesia. Data concerning the number of veins ligated and arterial preservation were recorded during each procedure. The amount of intraoperative and postoperative pain was assessed by means of visual analogue scale (VAS) scores. The recurrence rate was documented by color Doppler ultrasound examination. RESULTS The average number of ligated veins was 5.6 with a subinguinal dissection and 4.4 with the inguinal approach. Inadvertent injury of the spermatic artery occurred in 6 of 47 subinguinal and 3 of 50 inguinal dissections; the artery could not be identified during 2 subinguinal and 1 inguinal dissection. Recurrent varicocele was detected in 8% and 14.9% of patients after an inguinal and a subinguinal approach, respectively. The intraoperative VAS score was significantly higher in the inguinal than in the subinguinal patients (P = 0.008). CONCLUSIONS In our hands, the inguinal approach to the spermatic cord showed a trend toward an easier preservation of the artery and a reduced incidence of persistent pathologic vein reflux. The subinguinal approach had a lower degree of intraoperative pain. On the whole, an inguinal repair might be preferable when magnifying loupe are used for varicocelectomy.

Abstract
Male subfertility is a common problem with a complex etiology, requiring a complete andrological work-up for proper diagnosis. The male reproductive tract is controlled by a well-balanced hormonal system, in which hypothalamic (GnRH), pituitary (LH, FSH) and testicular hormones (androgens, inhibin B) participate. Any disturbance of this hormonal system may therefore lead to testicular dysfunction and interfere with the spermatogenesis process. In addition, also other components along the ductal system, such as epididymis, prostate and seminal vesicles, that improve sperm fertility by contributing their secretions to the semen, might function inadequately and thus fail to enhance the fertilizing capacity of the sperm cells. External factors (heat, chemicals, life style) and anatomical abnormalities (varicocele) were shown to have a negative influence on male fertility. In a number of patients genetic defects can be identified as the cause of their infertility. Laboratory tests are available to assess hormone concentrations, semen composition, accessory gland function and sperm cell function. Conventional semen analysis includes the determination of sperm concentration, semen volume, sperm motility (qualitative and quantitative), sperm morphology, sperm cell vitality, pH, leucocytes and antibodies. The usefulness of the determination of these parameters as predictor of fertility appears to be rather limited, however. Therefore, alternative tests, some based on more functional aspects (sperm penetration, capacitation, acrosome reaction), have been developed. Furthermore, there is an increasing attention for the assessment of DNA integrity, for instance by the flowcytometer-based Sperm Chromation Structure Assay (SCSA), as an additional or alternative parameter of sperm quality. It is likely and desirable that further assays with better predictive value are being developed in the near future.

Abstract
Varicocele is a very common condition. Although some patients may have pain, it is usually asymptomatic. Treatment of adolescent and pediatric patients is based on the desire to prevent testicular dysfunction and infertility that may be irreversible in adulthood. Venous embolization of the spermatic vein is an effective and minimally invasive method to occlude the varicocele and is known to improve testicular size and function. Embolization can be optimized by use of sclerosant, such as sodium tetradecyl sulfate (STS) foam or ethanol to permanently occlude the internal spermatic vein. About 10 to 15% of patients have recurrent varicocele after embolization. This is usually due to collateral vessels, such as from the right spermatic vein or the splanchnic veins. Embolizing as low as possible, while preventing pampiniform phlebitis by externally compressing the external inguinal ring, and empiric bilateral embolization appear to have the best outcome for preventing recanalization. Complications of varicocele embolization are uncommon. They include pampiniform phlebitis and venous thromboembolism into the renal vein or pulmonary artery.

Abstract
OBJECTIVE To determine the correlation between testicular volume measured with an orchidometer or high-resolution scrotal ultrasonography (US) with colour-flow Doppler analysis. PATIENTS AND METHODS In all, 159 men (mean age 36.6 years) presenting for infertility evaluation underwent both a physical examination by a one experienced examiner and high-resolution US with colour-flow Doppler analysis. An orchidometer was also used to measure testicular volume after stretching the scrotal skin tightly over the testis and after warming with a heating pad. The US was interpreted by a radiologist who had no knowledge of the orchidometer estimates. The volume was calculated as 0.71 x length x width x height. RESULTS For the right testes the mean orchidometer and US estimates were 18.4 and 18.3 mL, yielding a correlation coefficient of 0.72 (r (2) = 0.52, P < 0.01). On the left the respective values were 17.1 and 16.9 mL, with a correlation coefficient of 0.69 (r (2) = 0.48, P < 0.01). CONCLUSION Orchidometer estimates of testicular volume correlate closely and very significantly with US estimates in adults. In the hands of an experienced examiner orchidometer measurements provide an accurate, rapid and inexpensive assessment of testicular volume.

Abstract
PURPOSE Hydrocele seems to be the most frequent complication in children who undergo surgery for varicocele and the issue of the optimal management of hydrocele remains controversial. In this retrospective study we evaluated the incidence and management of hydrocele following surgical treatment of varicocele in children treated at 8 European centers of pediatric surgery. MATERIALS AND METHODS In a 5-year period 278 children between 7 and 17 years old underwent surgical treatment for unilateral left varicocele, including 187 using video surgery and 91 via an open inguinal approach. RESULTS At an average followup of 24 months (range 12 to 60) 34 children (12.2%) had a left hydrocele. Of the 278 children 14 (5%) were lost to followup. The hydrocele appeared between 1 week and 44 months (median 2 months) after surgery. Concerning hydrocele management 16 of 34 children (47%) were treated with scrotal puncture while under local anesthesia, which led to hydrocele regression after a median of 3 punctures (range 1 to 5), 12 (35.3%) underwent clinical observation since the hydrocele reduced spontaneously within a median of 12 months after its appearance and 6 (17.7%) were treated with open surgery. In 4 cases the hydrocele disappeared and in 2 it recurred after surgery and was successfully treated with punctures. CONCLUSIONS This study shows that the median incidence of hydrocele after varicocele surgery is about 12% but it seems higher after artery nonsparing vs sparing procedures (17.6% vs 4.3%). On the contrary, no difference was found when the procedure was performed using video surgery or with the open approach. Hydroceles generally develop a few months later but may also appear several years after the surgical repair of varicocele. Noninvasive procedures (scrotal punctures or clinical observation) seem to induce total hydrocele regression in more than 82% of cases. Children who undergo surgery for varicocele should undergo long-term followup to detect a possible hydrocele. In fact, the 5.4% of children lost to followup in our study may potentially have had a hydrocele. Surgery is not always successful for this condition, as shown in the 2 cases of recurrent hydrocele after surgical repair.

Abstract
PURPOSE We examined the impact on ipsilateral testicular volume in young men with varicocele and determined whether compensatory hypertrophy exists. MATERIALS AND METHODS Between April and November 2001, 2,700 men who were 20 years old and dwelling in the community were randomly selected at a 10% sampling fraction after a sampling process according to census district. A total of 2,080 men (77% response rate) agreed to participate in the study. All volunteers underwent standard evaluation, including medical history and physical examination. RESULTS Testicular volume on the affected side in men with varicocele was significantly smaller than that of the contralateral side, while testicular volume on the contralateral side was significantly larger than that of the left side in normal men. In those with unilateral varicocele testicular volume on the affected side did not depend on varicocele grade but contralateral testicular volume in men with grade I varicocele was significantly smaller than in men with higher grades of the entity. The rate of testicular atrophy increased depending on varicocele grade. CONCLUSIONS Varicocele negatively impacts testicular volume on the affected side in young men. Our findings suggest that men with higher grades of varicocele have a hypertrophied testis on the contralateral side.

Abstract
This study was conducted to examine the effect of height and weight on the incidence of varicocele in schoolboys aged 5-16 years and the impact of varicocele on testicular size. Genital stage, height, weight, varicocele grade, and testicular size were recorded for 3047 school boys who were clinically examined while standing by a specialist in urology. Left varicocele was detected in 98 of the boys who were all aged 9-16 years. The mean weight of boys with and without varicocele was 42 kg (95% confidence interval [CI] 40-44 kg) and 47 (95% CI 47-47 kg), respectively (p =.00). There was no difference in mean height between the two groups nor in left and right testicular volume. Although 6 boys with varicocele had a left testicular volume > or =2 mL less than right, there were also 7 boys of comparable age who had a left testicular volume > or =2 mL larger than right. The incidence of varicocele in Greek adolescents is low. Boys with varicocele weighed significantly less but there were no significant differences in height or left versus right testicular volumes. In the light of these observations, the use of left testicular hypotrophy (> or =2 mL compared with the right testicle) should be reconsidered as an indicator for varicocele-induced damage of the testicle in this age group.

Abstract
OBJECTIVE To evaluate the outcome of laparoscopic Palomo varicocelectomy (LPV) in young boys who had undergone previous ipsilateral inguinal surgery (in whom potentially the arterial supply to the testicles may be compromised) in an attempt to assess its safety for the collateral vascular supply in such cases. PATIENTS AND METHODS Over a 5-year period (1995-2000) 44 patients underwent LPV, where both the spermatic artery and vein were ligated high above the internal ring. Thirteen patients had undergone previous ipsilateral inguinal surgery, which included inguinal hernia repairs in five, orchidopexy in two, communicating hydrocele repair in three and previous varicocele repair in three. All patients were followed clinically at 3 months and 1 year after surgery. RESULTS There were no complications related to laparoscopy or varicocele ligation. No patient developed ipsilateral testicular atrophy; moreover the testis size remained stable or was associated with compensatory growth in all patients. CONCLUSION Previous inguinal surgery involving the ipsilateral testicle does not appear to affect the collateral blood circulation to the affected testis in boys who undergo LPV mass ligation of the internal spermatic vein and artery. LPV for varicocele is safe in boys who have undergone previous inguinal surgery, suggesting that an adequate collateral blood supply is present.

Abstract
OBJECTIVE Inhibin B is secreted by Sertoli cells in response to FSH and is the major feedback regulator of FSH secretion in man. The serum inhibin B level has emerged as a good marker of spermatogenesis and Sertoli cell function. Varicocele has been associated with infertility and disturbed spermatogenesis. We have studied the effect of varicocele treatment on serum inhibin B levels, with the aim of investigating the effect on spermatogenesis and the involvement of the Sertoli cell in varicocele pathophysiology. DESIGN AND PATIENTS In a pre-post test design, the effect of varicocele surgery on inhibin B levels was studied in 30 infertile men. MEASUREMENTS Endocrinology (inhibin B, FSH, LH, SHBG and testosterone) and semen analysis (sperm concentration, motility and morphology). RESULTS In men receiving varicocele treatment, a significant increase in serum inhibin B levels was observed from 133.9 +/- 13.4 pretreatment to 167.8 +/- 16.1 ng/l after treatment (mean +/- SEM, P < 0.0001). No significant changes were observed in serum levels of FSH, LH and testosterone. The serum SHBG level decreased from 32.9 +/- 3.5 to 28.6 +/- 3.4 nmol/l (mean +/- SEM, P = 0.04) and the free androgen index was significantly increased from 66 +/- 5.9 pretreatment to 85 +/- 6.8 after treatment (P = 0.02, mean +/- SEM). Semen analysis showed a significant improvement in sperm concentration, from 6.5 +/- 1.9 pretreatment to 19.3 +/- 4.9 x 106/ml after treatment (P = 0.003, mean +/- SEM), and in sperm motility from the baseline level of 17 +/- 3 to 32 +/- 4% after treatment (P = 0.001, mean +/- SEM). CONCLUSIONS Varicocele treatment can increase serum inhibin B levels, indicating improvement of spermatogenesis and Sertoli cell function. This finding suggests that the pathophysiology of varicocele involves impairment of Sertoli cell function or a different distribution of germ cell stages.

Abstract
BACKGROUND The aim of this study was to evaluate the results and complications of laparoscopic varicocelectomy in children. METHODS Over a 36-month period, 211 children underwent laparoscopic treatment of varicocele. Their ages ranged between 6 and 17 years; the varicocele was located on the left side in 209 cases (99.1%) and was bilateral in 2 (0.9%). In 195 patients the laparoscopic transperitoneal approach was used and in 16 retroperitoneoscopy was used. Thirty children (14.2%) underwent ligation of the veins alone, and 181 (85.8%) underwent ligation of testicular veins and artery. In 15 (7.1%) cases an additional procedure was applied during the same operation. RESULTS Average operating time was 30 minutes and hospitalization about 24 hours. At an average follow-up of 26 months, there were 19 (9%) postoperative complications: 14 children had a left hydrocele, 3 children a scrotal emphysema, and 2 an umbilical granuloma. There were 5 recurrences of varicocele in our series: 2 (2 of 30, 6.6%) after the Ivanissevitch procedure, and 3 (3 of 181, 1.6%) after Palomo's. Testicular atrophy did not occur in any patient of this series. CONCLUSIONS This preliminary experience shows that the results of the laparoscopic approach are comparable to those of the open approach. The ligation of testicular veins and artery is preferable to the ligation of the testicular veins alone. Hydrocele seems to be the most frequent postoperative complication and a potential problem, especially in children operated on with the Palomo procedure.

Abstract
PURPOSE We report preliminary results of a multicenter study of the Italian Society of Video Surgery in Infancy on the laparoscopic treatment of pediatric varicocele. MATERIALS AND METHODS A total of 161 children 6 to 16 years old (median age 12.5) underwent laparoscopic treatment of varicocele at 6 pediatric surgery divisions. Varicocele was on the left side in 159 cases (98.7%) and bilateral in 2 (1.3%). Two boys had recurrent left varicocele. All children were treated with laparoscopy, including ligation of the spermatic veins only in 28 (17.3%), and ligation of the testicular veins and artery in 133 (82.7%). In 10 boys (6.2%) an additional procedure was done simultaneously, including closure of an apparently patent peritoneal vaginal duct on the right side in 7 and resection of epiploic adhesions between the intestinal loops and abdominal wall from previous appendectomy in the remaining 3. RESULTS Average operative time was 30 minutes and hospitalization was about 24 hours. At followup there were 13 minor complications (8%), including left hydrocele in 9 children who underwent the Palomo technique, minor scrotal emphysema in 2 and umbilical granuloma in 2. In our series varicocele recurred in 1 boy (3.5%) who underwent ligation of the spermatic veins only and in 3 (2.2%) treated with the Palomo technique. CONCLUSIONS Our preliminary experience shows that the results of the laparoscopic approach are comparable to those of the open approach. However, the important advantages of laparoscopy over the open approach are its minimal invasiveness and precision of intervention. Moreover, laparoscopy allows treatment of other intra-abdominal pathological conditions using the same anesthesia, as in 10 patients in our series. We believe that ligating the testicular veins and artery is preferable to ligating the testicular veins only, even if the incidence of hydrocele is not negligible after the Palomo procedure.

Abstract
OBJECTIVE To evaluate the contractile response of the vas deferens in a model of stress, to determine any changes in sympathetic activity as a result of stress in the ipsilateral testis, which decreases blood flow to the contralateral testis. MATERIALS AND METHODS The study comprised two groups of six rats each; group 1 underwent a sham operation, and in group 2 the right testis was placed into the abdominal cavity and the vas deferens ligated. After 30 days, the vasa deferentia were resected bilaterally and their isometric contractions recorded. Electrical-field stimulation (EFS) was applied through a pair of platinum electrodes and concentration-response curves constructed for noradrenaline at 37 degrees C and to a solution containing 80 mmol/L K+. RESULTS The vasa deferentia in both groups showed similar contractile responses to EFS, which were frequency-dependent and maximal at 80 Hz. Noradrenaline-induced contractile activity was lower in amplitude in the vasa deferentia of group 2 than in the contralateral and ipsilateral vasa deferentia of group 1, which were not significantly different from each other. All groups responded similarly to high K+. CONCLUSION Intra-abdominal placement of the testes with vas deferens ligation decreased the contractile response to noradrenaline in the ipsilateral vas deferens without altering the contractile response to EFS and high K+. This difference could be caused by a reduction in the number of postjunctional alpha-adrenergic receptors or decreased receptor sensitivity. Both possibilities suggest that the vas deferens may initiate sympathetic activity, which may be responsible for contralateral testicular deterioration.

Abstract
The debate regarding the efficacy of varicocele ligation for improvement of semen parameters and pregnancy rates is ongoing. In addition, no consensus exists as to the benefit of treatment of subclinical varicoceles. The aim of this study was to investigate, retrospectively, the effect of high ligation of both subclinical and clinical varicoceles on sperm count and motility. The value of several factors from history-taking and physical examination for the prediction of successful varicocelectomy was analysed. A total of 139 patients, operated on for a unilateral varicocele on the left side, were studied. Varicoceles were subclinical in 73 patients, based on colour Doppler ultrasonography, and 66 varicoceles were clinical, based on palpation in addition to ultrasonography. Comparison of semen parameters before and after surgery revealed a significant improvement. The median sperm count increased from 10.0 to 14.7, and from 18.2 to 28.6 million/ejaculate, in patients with subclinical and clinical varicoceles, respectively (p < 0.001). The percentage improvement in median sperm count in subclinical varicoceles was not statistically different from the improvement in clinical varicoceles. Mean progressive motility improved significantly after ligation (p < 0.001). The improvement in motility in subclinical varicoceles, from 16 to 23%, was significantly larger than the 24 to 27% improvement in clinical varicoceles. The increase in sperm count was related positively to testicular volume before surgery (p < 0.05). The increase in sperm motility was significantly lower in patients with a history of cryptorchidism (n = 22, p < 0.05). The present data show that ligation of varicoceles detected using Doppler ultrasonography, whether palpable or not, results in an increase in sperm concentration and motility.

Abstract
Unilateral spermatic cord torsion in the presence or absence of ipsilateral testis causes hypoxia in the contralateral testis. An experimental study was conducted to find the most important structure that causes contralateral testicular hypoxia following ipsilateral twisting. In five groups each consisting of 10 rats sham operations, epididymoorchiectomy, spermatic cord torsion, spermatic cord torsion following subepididymal orchiectomy or spermatic cord torsion following epididymoorchiectomy were performed. Lactic acid, hypoxanthine and thiobarbituric acid reactive products of lipid peroxidation (TBAR) were determined in the contralateral testis. While lactic acid, hypoxanthine and TBAR values did not differ significantly following sham and epididymoorchiectomy procedures, evaluation of other groups revealed significantly increased values compared with sham and epididymoorchiectomy groups. Since torsion of only spermatic cord and testicular vasculature causes contralateral testicular hypoxia, testis and epididymis do not seem to be mandatory for occurrence of contralateral testicular hypoxia. Testicular artery under distress seems to be the most important structure that results in contralateral testicular hypoxia following torsion.

Abstract
Pediatric patients presenting with painless scrotal masses can be perplexing because of the long differential diagnosis. A careful plan based on the physical examination and sonogram findings localizes the mass to the testis or an extratesticular location. Sonography distinguishes solid from cystic lesions. Subsequent management is based on the location and nature of the mass. Intratesticular masses are assumed to be malignant, but testis-sparing surgery is possible in pediatric patients. Extratesticular cystic lesions are likely benign and are managed according to the specific diagnosis. Solid extratesticular lesions require exploration to establish the correct diagnosis.

Abstract
PURPOSE We designed a randomized prospective study of male adolescents with moderate and severe varicoceles to determine whether prophylactic varicocele repair is beneficial. MATERIALS AND METHODS We evaluated 2,100 boys (10 to 20 years old) for genitourinary abnormalities. From this population 2 groups of adolescents 15 to 19 years old with grade 2 or 3 varicoceles were created, including 88 who underwent varicocele repair and 36 controls. Testicular volume and pampiniform vein diameter were measured, and Doppler ultrasound was performed. RESULTS After 12 months volume of the involved left testis increased to almost normal in treated boys (mean atrophy index 12.7% at surgery and 3% 12 months later). In controls the corresponding atrophy indexes were 10 and 9%, respectively. The relative increase in left testicular volume was 26% in the surgery group and 11% in controls. In the surgery group mean pampiniform vein diameter decreased from 2.8 preoperatively to 2 mm. postoperatively but there was no change in controls. CONCLUSIONS Varicocele repair in adolescents with moderate and severe varicocele reversed testicular growth arrest and resulted in catch-up growth within 12 month of surgery.
