Varicocele is a common finding in men. Varicocele correction has been advocated for young patients with testicular hypotrophy, but there is a lack of morphofunctional follow-up data. We assessed whether percutaneous treatment of left varicocele is associated with testicular "catch-up growth" in the following 12 months by retrospectively reviewing data from an electronic database of 10 656 patients followed up in our clinic between 2006 and 2016. We selected all young adults (<35 years) with left varicocele who underwent percutaneous treatment, had a minimum of 12 months' ultrasound imaging follow-up, and had no other conditions affecting testicular volume. One hundred and fourteen men (mean±standard deviation [s.d.] of age: 22.8 ± 5.4 years) met the inclusion and exclusion criteria. Left testicular hypotrophy (LTH), defined as a ≥20% difference between left and right testicular volume at baseline, was observed in 26 (22.8%) men. Participants with LTH (mean±s.d.: 14.5 ± 2.7 ml) had lower baseline testicular volume compared to those without LTH (mean±s.d.: 15.7 ± 3.8 ml; P = 0.032). Repeated measures mixed models showed a significant interaction between LTH and time posttreatment when correcting for baseline left testicular volume (β = 0.114, 95% confidence interval [CI]: 0.018-0.210, P = 0.020), resulting in a catch-up growth of up to 1.37 ml per year (95% CI: 0.221-2.516). Age at intervention was also associated with reduced testicular volume (-0.072 ml per year, 95% CI: -0.135--0.009; P = 0.024). Percutaneous treatment of left varicocele in young adults with LTH can result in catch-up growth over 1 year of follow-up. The reproductive and psychological implications of these findings need to be confirmed in longer and larger prospective studies.

We report the largest single-center experience with robotic-assisted microscopic varicocelectomy (RAMV) in male infertility. From August 2012 to February 2015, men with infertility of at least a year and varicoceles underwent RAMV by a single surgeon. Varicocele was diagnosed on physical examination and confirmed by ultrasound by a single ultrasonographer. Preoperative hormone panel, semen analyses, and testicular Doppler ultrasound were obtained from all men and repeated at 3 months. One hundred and forty consecutive men (258 varicocelectomies) were included. Mean age and duration of infertility was 36.4 and 2.8 years, respectively. Median total and free testosterone increased by 145 ng dl^-1 and 4.3 pcg ml^-1 (44.3%), respectively (P < 0.0001). Median sperm concentration increased by 37.3% (P < 0.03). Median sperm motility and morphology did not significantly change. Median left and right testicular volume increased by 22.3% (P < 0.0001) and 12.6% (P < 0.0006), respectively. Hydroceles occurred 0.8% of procedures. We had no testicular artery injuries. Persistence of varicocele by Doppler ultrasound was 9.6%. Only 37.3% of patients required pain medications postoperatively. We concluded that RAMV is a safe and effective alternative for varicocele repair with outcomes comparable to historical traditional microsurgical approach.

Objective: To investigate the clinical effect and feasibility of internal spermatic vein-inferior epigastric vein (ISV-IEV) bypass surgery in the treatment of varicocele complicated by left renal vein nutcracker syndrome (NCS). METHODS: We retrospectively analyzed the clinical data about 30 cases of varicocele with left renal vein NCS treated by ISV-IEV bypass surgery in our hospital from June 2014 to February 2017. We reviewed the follow-up data and results of ultrasonography, routine urianlysis and semen routine examination. RESULTS: All the operations were successfully accomplished and postoperative color Doppler ultrasonography showed that varicocele was cured in all the cases. At 6 months after surgery, sperm concentration and the percentage of grade a+b sperm were significantly improved (［34.47 ± 8.60］ ×10⁶/ml and ［63.54% ± 9.58］ %) as compared with the baseline (［19.90 ± 8.97］ ×10⁶/ml and ［37.93 ± 8.73］ %) (P <0.05). Hematuria was cured in 23 and alleviated in 1 of the 24 cases. Proteinuria disappeared in all the 14 cases, with neither scrotal pain symptoms nor obvious complications. CONCLUSIONS ISV-IEV bypass surgery, with its advantages of safety, effectiveness, minimal invasiveness, and simple operation, deserves wide clinical application in the treatment of varicocele with left renal vein NCS.

ObjectiveTo study the correlation of the inner diameter parameters of the spermatic vein in different positions and states of the varicocele (VC) patient with the results of seminal examination.

METHODSA total of 149 VC patients underwent ultrasonography, routine semen examination, and sperm morphological analysis. The parameters obtained from ultrasonography included the bilateral testis volume in a supine position, the largest spermatic vein diameter in a supine position at rest (DSR), the largest spermatic vein diameter in a supine position following Valsalva manoeuvre (DSV), the largest spermatic vein diameter in an upright position at rest (DUR), and the largest spermatic vein diameter in an upright position following Valsalva manoeuvre (DUV). Then we calculated the parameters △DS=DSV－DSR, △DU=DUV－DUR, △DR=DUR－DSR, and △DV=DUV－DSV and analyzed the correlation of the above parameters with the results of semen examination using the ROC curve.

RESULTSBased on the results of semen examination, 119 (79.87%) of the patients were allocated to the abnormal group and the other 30 (20.13%) to the normal group. Statistically significant differences were observed between the two groups in △DU (P=0.007), △DR (P=0.0001), and △DV (P=0.04), but not in DSR (P=0.35), DSV (P=0.34), DUR (P=0.06), DUV (P=0.12), and △DS (P=0.64), nor in the volume of the testis affected (P=0.323). The area under the ROC curve was 0.55 for DSR, 0.57 for DSV, 0.64 for DUR, 0.62 for DUV, 0.49 for △DS, 0.28 for △DU, 0.86 for △DR, and 0.69 for △DV. The corresponding cutoff values were 2.25, 2.51, 2.48, 2.63, 0.30, 0.23, 0.25, and 0.20, the corresponding sensitivities of semen detection were 50.42%, 65.55%, 60.50%, 60.50%, 49.90%, 29.41%, 79.83%, and 65.55%, and the corresponding specificities were 56.67%, 63.33%, 63.33%, 63.33%, 56.67%, 33.33%, 80%, and 63.33%, respectively.

CONCLUSIONSThe difference between the largest spermatic vein diameters in supine and upright positions at rest provides a high diagnostic accuracy for semen detection and helps to predict abnormality in seminal examination for VC patients.

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%). The optimal age for varicocelectomy was answered as 13.8±2.3 years mean. 32 respondents (86%) have used ultrasonography to aid in the diagnosis of varicoceles, and 26 respondents (70%) have considered repairing varicocele incidentally detected on ultrasonography. In an otherwise asymptomatic patient with varicocele, 17 respondents (46%) considered surgery for grade 3, but 15 respondents (41%) would not repair the varicocele. The most commonly used surgical approach was subinguinal microsurgical (n=19, 51%), followed by inguinal (n=9, 24%) and laparascopic (n=5, 14%) procedures. The most commonly experienced post-operative complication was recurrence (n=22, 59%) followed by persistence (n=13, 35%) and hydrocele (n=10, 27%). 28 respondents (76%) did not have long-term follow-up data including regarding fertility on their varicocele patients. Our survey demonstrates that there is lack of consensus on diagnosis and management of pediatric and adolescent varicoceles among pediatric urologists. A prospective randomized study of pediatric and adolescent varicoceles is needed to assess the outcomes and develop universal management guidelines.

PURPOSE: To determine effectiveness of Valsalva maneuver and standing position on scrotal color Doppler ultrasound (CDU) for the varicocele diagnosis. MATERIALS AND METHODS: We reviewed the physical examination and CDU finding in 87 patients who visited National Police Hospital from January 2011 to April 2014. Diameters of pampiniform plexus were measured bilaterally during resting and Valsalva maneuver in the supine position and standing position. We calculated the ratio of mean of maximal vein diameter (mMVD) during resting and Valsalva maneuver (resting-Valsalva ratio) and compared in the both position. RESULTS: In the resting and supine position, mMVD of varicocele testis units were 1.8 mm, 2.1 mm, 2.6 mm (grades I, II, III, respectively), and that of normal testis units (NTU) 1.2 mm. During Valsalva maneuver in the supine position, mMVD were 3.0 mm, 3.4 mm, 4.2 mm (grades I, II, III) vs 1.8 mm (NTU) (p=0.007, p<0.001, p<0.001, respectively). Average of resting-Valsalva ratio in the supine position were 0.69, 0.74, 0.74 (grades I, II, III) and 0.67 (NTU). Whereas in the resting and standing position, mMVD were 2.8 mm, 3.3 mm, 3.8 mm (grades I, II, III) and 1.8 mm (NTU) (p=0.002, p<0.001, p<0.001). During Valsalva maneuver in the standing position, mMVD were 5.0 mm, 5.8 mm, 6.6 mm (grades I, II, III) and 2.5 mm (NTU) (p=0.002, p<0.001, p<0.001). And average resting-Valsalva ratio were 0.76, 0.90, 0.71 (grades I, II, III) and 0.26 (NTU), which showed significant differences from all grades (p<0.001, p<0.001, p<0.001). CONCLUSIONS: It is suggested that the standing position and Valsalva maneuver during CDU could improve diagnostic ability for varicocele. Resting-Valsalva ratio in the standing position could be a new diagnostic index for varicocele diagnosis using CDU.

PURPOSE: We aimed to evaluate the efficacy of using testicular biopsy histopathology as an indicator of the success of loupe-assisted subinguinal varicocelectomy in non-obstructive azoospermia (NOA) patients. MATERIALS AND METHODS: In a 2-year period, a prospective study was carried at Minoufiya University Hospital on 20 NOA patients with clinical bilateral varicoceles. These patients underwent loupe-assisted subinguinal varicocelectomy with simultaneous testicular biopsy. All patients were evaluated by determining their hormonal profile and performing semen analyses and scrotal Doppler and transrectal ultrasonography. Two semen analyses showing azoospermia were performed before the surgery and two semen analyses were received at 3 and 6 months post-operatively for follow-up. RESULTS: The mean age was 29.9+/-6.7 years, and the mean follow-up duration was 17.3+/-8.3 months. We noted the restoration of spermatogenesis in six men (30% of all patients). Testicular biopsy results were as follows: hypospermatogenesis in 7 patients, maturation arrest in 3, and Sertoli cell-only syndrome in 10. The improvement in the sperm counts of these patients ranged from 3 million to 15 million/mL. Sperms were recovered in the hypospermatogenesis (6 patients, 85.5%) patients only, but other patients with testicular biopsy results of Sertoli cell-only or maturation arrest did not show any improvement in their semen parameters. CONCLUSIONS: Testicular biopsy results showed that hypospermatogenesis patients have a better chance of improvement in their semen analysis after varicocelectomy in contrast to NOA patients with Sertoli cell-only syndrome or maturation arrest.

PURPOSE: It has been reported that varicocele is found less frequently in obese men. Accordingly, we evaluated varicocele patients and statistically analyzed the correlation between varicocele and somatometric parameters. MATERIALS AND METHODS: A total of 211 patients underwent surgery for varicoceles. All patients underwent history taking, physical examination, and scrotal ultrasound to determine the presence and severity of varicocele. An age-matched control group consisted of 102 patients who were found not to have varicocele according to physical examinations and scrotal ultrasound. The age, weight, height, and body mass index (BMI) of the two groups were compared. The statistical analyses were performed by use of PASW Statistics ver. 18.0. A p-value of less than 0.05 was used for statistical significance. RESULTS: In the varicocele group, the mean age, height, weight, and BMI were 29.42+/-14.01 years, 168.53+/-9.97 cm, 62.14+/-13.17 kg, and 21.66+/-3.21 kg/m2, respectively. The distribution of varicocele grade was as follows: 103 (48.8%) grade III, 72 (34.1%) grade II, and 36 (17.1%) grade I. In the control group, the mean age, height, weight, and BMI were 30.83+/-17.31 years, 161.93+/-19.83 cm, 64.69+/-17.86 kg, and 24.04+/-3.64 kg/m2, respectively. Analyzing these data specifically in adolescents, they showed significant differences in age, height, and BMI (p=0.000, p=0.000, and p=0.004, respectively) between two groups. There were no significant differences in somatometric parameters between patients with different grades of varicocele. CONCLUSIONS: Our results showed that patients with varicoceles were significantly taller and had a lower BMI than did patients without varicoceles, especially among adolescents. Carefully designed future studies may be needed.

PURPOSE: The improvement of testicular volume, testosterone levels and sperm concentration was suggested to be significantly associated with the number of internal spermatic veins (ISVs) ligated during varicocelectomy. Herein, we investigated preoperative color Doppler ultrasonography (CDU) findings as potential preoperative predictors of the number of ISVs requiring ligation during microsurgical subinguinal varicocelectomy. MATERIALS AND METHODS: In a prospective evaluation of 40 patients, maximal vein size and maximal reflux velocity were measured, while the total cross-sectional area of the affected testicular veins during a Valsalva maneuver was calculated using CDU by a single uroradiologist. Microsurgical subinguinal varicocelectomies were performed by one urologist. RESULTS: Among the semen parameters, semen morphology showed significant improvement (p=0.033), which was much clearer in the patients with a higher number of ISVs ligated than a lower number of ISVs ligated. Among the various preoperative variables, maximal reflux velocity and total cross-sectional area on CDU were related to the number of ISVs ligated (r=-0.442, p=0.004; r=0.594, p=0.000, respectively). Furthermore, univariate and multivariate linear regression analyses showed that maximal reflux velocity and total cross-sectional area on CDU were independent predictive factors of the number of ISVs ligated. CONCLUSION: Maximal reflux velocity and total cross-sectional area on CDU were related to the number of ISVs ligated. This means that the maximal reflux velocity and total cross-sectional area measured by preoperative CDU can predict the number of ISVs requiring ligation during microsurgical subinguinal varicocelectomy, which might be related to significant improvement of semen parameters after varicocelectomy.
