RESUMO

OBJECTIVE: To evaluate the clinical efficacy of microscopic internal spermatic-inferior epigastric vein anastomosis in the treatment of left varicocele and compare it with microscopic spermatic vein ligation for the same condition. METHODS: A retrospective analysis of 74 patients with left varicocele between July 2020 and July 2022 was performed. The patients were divided into two groups based on the surgical method used. Group A consisted of 37 patients who underwent microscopic internal spermatic-inferior epigastric vein anastomosis, while Group B consisted of 37 patients who underwent microscopic spermatic vein ligation. Comparison of preoperative and postoperative semen quality, reproductive hormone levels, scrotal ultrasound results, duration of surgery, length of hospital stay, postoperative recurrence rate, and occurrence of complications with a follow-up time of 12 mo between two groups. RESULTS: Both groups showed significant improvements in semen quality and serum reproductive hormone levels. The Group A demonstrated significantly improved sperm forward motility compared to Group B, but had longer operation times and hospital stays (P < 0.05). After 1 year of follow-up, 8 partners in Group A and 6 partners in Group B achieved natural conception, with no significant difference between the two groups. There were no recurrences observed in either group during the follow-up period, and no significant statistical differences were found in other postoperative observation indicators. CONCLUSIONS: Both microscopic internal spermatic-inferior epigastric vein anastomosis and microscopic spermatic vein ligation are effective surgical methods for treating left varicocele. Anastomosis surgery provides greater improvement in sperm motility, although it is associated with longer operation times and hospital stays.

RESUMO

BACKGROUND: Staged laparoscopic management of intra-abdominal testes using pedicular section is recognized as gold standard technique, successful in 85 % of cases for scrotal testicular position with less than 10 % testicular atrophy. Recently, Shehata proposed a new technique without pedicular division for these testes, using spermatic vessels traction, but did not provide a comparative study of the two techniques. OBJECTIVE: To evaluate the laparoscopic spermatic pedicular traction (Shehata technique, ST) for the treatment of intra-abdominal testis, as an alternative to gold standard pedicular section (2-stage Fowler-Stephens, FS). STUDY DESIGN: Intra-abdominal testes of 129 patients in two tertiary pediatric urology centers were managed laparoscopically (2011-2019) either by 2-stage FS orchidopexy or ST according to the surgeon preference. Testicular position and size were statistically compared. RESULTS: A total of 147 testes were pulled down by 80 ST and 67 FS, including 18 bilateral cases. Median (IQR) age at surgery was 24.2 (15.6-46.4) months (ST) and 18.3 (13.1-38.2) months (FS) (p = 0.094). Scrotal pulling-down of the testis was performed after a median (IQR) period of 2.3 (1.6-3.4) months (ST) and 6.1 (4.7-8.3) months (FS), respectively (p < 0.005). Although ST had collapsed in 17 cases (21.3 %), only one (1.3 %) redo procedure was required. After a median (IQR) follow-up of 22 (12-40) and 19 (8.75-37) months (p = 0.59), the testis was in the scrotum in 85 % and 81 % of ST and FS cases, respectively (p = 0.51). Testicular atrophy occurred in 10 % of ST and 13.4 % of FS (p = 0.61). Multivariate analysis using the propensity score analysis did not identify any difference between the two techniques. DISCUSSION: Our results seem to confirm that FS and ST achieve the same results regarding final testicular position and testicular atrophy rate, with a long-term follow-up. Our study supports pediatric surgeons to favor laparoscopic spermatic pedicular traction (ST) which preserves the testicular vascularization and may ensure better spermatogenesis after puberty. More details on the size and position of the testicle at the beginning of the first laparoscopy seem however essential to assess more accurately the outcomes of each surgical technique. Our outcomes will also be re-evaluated when our patients have reached puberty, from an exocrine and endocrine points of view. CONCLUSIONS: This study showed similar results after laparoscopic traction or section of spermatic vessels for intra-abdominal testis in a long-term follow-up, providing more evidence for the use of ST as a valuable alternative to FS.

RESUMO

INTRODUCTION: Identification and preservation of testicular artery and lymphatic vessels during microsurgical varicocelectomy can be tedious if adhered encompassing venous network is encountered. A venous bypass from internal spermatic to saphenous or inferior epigastric vein, that have been described for varicocele treatment, may be used in such situations. This paper describes a simplified modification of the venous bypass technique that reroutes the testicular blood to the superficial epigastric vein, which can easily be found in the incisional wound. Surgical technique and anastomotic patency test are described, and indications and results are discussed. MATERIALS AND METHODS: During 2020 and 2021, 32 adolescent patients underwent microsurgical varicocelectomy. In eight patients additional microsurgical testicular vein-superficial epigastric vein microvascular bypass was done. The indication for bypass was difficult identification of testicular artery and/or lymphatic vessels due to adhered venous plexus. RESULTS: Varicocele resolution was noted in all eight patients with clinical and/or semen analysis improvement. There were no complications or recurrences. Average length of procedure was 65 minutes. All patients were discharged within 24 hours and no antiplatelet or anticoagulant therapy was used. CONCLUSION: Testicular vein to superficial epigastric vein anastomosis is a useful and simplified venous bypass technique that reroutes the blood from the pampiniform plexus to the femoral vein. It can be done as an adjunct to microsurgical varicocelectomy in selected patients through a standard incision.

RESUMO

The three-dimension digital image microscope system (3D-DIM) with a better ergonomic design and equipment characteristics can contribute to the achievement of good results during microsurgery. In this study, the safety and efficiency of 3D-DIM assisted varicocelectomy was evaluated. From July 2019 to November 2019, fifteen cases with varicocele (20 sides of varicocele in total) were included, seven cases underwent 3D-DIM-assisted modified microsurgical subinguinal varicocelectomy, and eight cases underwent modified microsurgical subinguinal varicocelectomy under standard operating microscope (SOM). The mean operative time of 3D-DIM group (67 ± 12.3 min) was a little longer than that of SOM group (55 ± 12.9 min) (p < 0.05). There was no significant difference between the two groups in the number of internal spermatic arteries, internal spermatic vein, lymphatics, gubernacular vein, external spermatic vein and post-operation complications. The 3D-DIM showed a significant difference in image definition for nurse (p < 0.01) and in doctor-nurse cooperation (p < 0.05) over SOM. The 3D-DIM with better ergonomic design and image definition can be applied to perform microsurgical subinguinal varicocelectomy, and could improve the surgeon's fatigue and doctor-nurse cooperation. We believe that the 3D-DIM would be widely used in the field of male infertility microsurgery in the near future.

RESUMO

The aim of the study was to investigate the micro-structures of the spermatic cord using histological examination with three-dimensional (3D) reconstruction of the serial tissue sections of the cord for clinical application in microscopic varicocelectomy. Human spermatic cord specimens obtained from 13 adult male cadavers were used to prepare serial transverse sections. The sections were stained to allow observation of the spermatic cord microstructures. The 3D reconstruction was performed with digitized serial sections by Mimics software. The microscopic varicocelectomy was performed based on the anatomical results of 3D reconstruction of the spermatic cord. The results showed the number of small spermatic veins, large spermatic veins, arteries, lymphatics or nerves were not markedly different between the subinguinal and inguinal regions or between the right and left sperm cord. The number of medium spermatic veins in the subinguinal region was obviously higher than at the inguinal level. The internal spermatic vessels and the vas deferens together with other associated vessels within the cremaster were separately enclosed by two thin and translucent sheaths, the internal spermatic fascia and the vas deferens fascia. We conclude that internal spermatic vessels and the vas deferens together with the associated neurovascular vessels are wrapped by two distinct sheaths separating them from the surrounding tissues. Microscopic varicocelectomy based on the anatomical results of 3D reconstruction of the spermatic cord is feasible.

RESUMO

The aim of this study was to evaluate the role of platelet count (PLT) and platelet volume indices (PVI) such as mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) as a clinical biomarker in 64 infertile males with varicocele and 45 controls. In addition, semen parameters, serum total testosterone, FSH and testicular volume were measured before and at 6 months after varicocelectomy. The mean PLT, MPV, PDW and PCT were 231 ± 42 × 103/µl, 9.6 ± 1.8 fl, 16.2 ± 2.5 fl and 0.18% in the patient group respectively. When the patient and control groups were compared, there was a significant increase in mean MPV, PDW and PCT (p < .0001), while platelet count was lower in patients than control group, but with no significant relationship. MPV had a significant negative correlation with total testosterone (p < .03). No significant correlations were found between PVI and testicular volume. After follow-up of 37.1 ± 1.9 months, a significant negative correlation was found between the preoperative MPV and varicocelectomy outcome in terms of semen values (p < .007). So, the increase in MPV and low total testosterone in men with varicocele may be a feature of high risk of infertility.

RESUMO

The pathophysiology of varicocele remains to be unknown. Several genetic factors have been implicated in varicocele etiopathogenesis. We studied the relationship between NOS3 c.894G>T, c.786T>C and 4b/a polymorphisms to varicocele risk and their prognostic value as regards improvement of the post-operative seminal parameters &/or seminal malonaldehyde levels. The three NOS3 polymorphisms were evaluated in 100 patients with varicocele and 100 healthy subjects by RT-PCR. Seminal plasma MDA level was measured pre-operatively and 3 months after varicocelectomy by the thiobarbituric acid method. The GT, TT, TC and bb genotypes of NOS3 polymorphism were more commonly observed in varicocele patients (30%, 9%, 28% and 70% respectively) compared to normal controls (12%, 0%, 10% and 50% respectively). The mean percentage of post-varicocelectomy seminal MDA reduction was highest with the GT genotype (p < .001). Genotypes GT+TT, TC and bb were associated with varicocele occurrence in our patients. The T (c.894G>T), C (c.786T>C) and b (NOS3 intron 4 VNTR) alleles were significantly associated with varicocele occurrence in our cohort of patients. We also report a better response regarding the reduction of seminal MDA after varicocelectomy with the GT and ba genotypes.

RESUMO

One of the most important causes of varicocele-related infertility is oxidative stress (OS). One of the markers considered as an indicator of OS is thiol-disulphide homeostasis (TDH). Based on the hypothesis that OS should decrease after varicocelectomy in the light of this information, in our current study, we investigated the relationship between TDH levels and sperm parameters. The data of 56 infertile varicocele men were prospectively analysed. The post-operative total and native thiol levels were significantly higher than those pre-operative total and native thiol levels (477.7 & 436.7 nmol/L, 417.6 & 372.1 nmol/L). Positive correlation was found between total thiol change and change in semen volume (ρ: .277, p: .039), ratio of spermatozoa with normal morphology (ρ: .342, p: .01), progressive (ρ: .334, p: .012) and nonprogressive motility (ρ: .385, p: .003). Positive correlation was also found between native thiol change and semen volume (ρ: .349, p: .008), ratio of spermatozoa with normal morphology (ρ: .362, p: .006), progressive (ρ: .297, p: .026) and nonprogressive motility (ρ: .368, p: .005). Change in the level of TDH was found as positively correlated with progressive and nonprogressive motility change. According to these results, OS decreases with varicocelectomy in infertile patients and TDH can be used as a useful method for measuring OS.

RESUMO

Oxidative stress plays an important role in the development of infertility secondary to varicocele. We aimed to investigate the dynamic thiol-disulphide homeostasis as an oxidative stress marker in the spermatic vein of infertility secondary to varicocele. Sixty-one patients with varicocele were included in the study. Blood was drawn from the median cubital vein and the testicular venous return side before the spermatic vein was separated during surgery. Total thiol, native thiol, disulphide, ischaemia modified albumin (IMA) and albumin values were measured from both the dilated spermatic vein and the median cubital vein. The disulphide/native thiol, disulphide/total thiol and native thiol/total thiol ratios were determined. The mean age of the patients was 27.0 ± 6.68 (15-50) years. While the albumin, native thiol and total thiol values and the native thiol/total thiol ratio were significantly lower (p = 0.004, p < 0.001, p < 0.001, p < 0.001 respectively), the IMA value and the disulphide/native thiol and disulphide/total thiol ratios were significantly higher (p < 0.001, p < 0.001, p < 0.001 respectively) in the samples taken from spermatic venous blood. Thiol-disulphide balance had deteriorated towards disulphide formation in the spermatic vein compared with the peripheral vein. Abnormal thiol-disulphide balance may be an independent risk factor for infertility secondary to varicocele.

RESUMO

PURPOSE: Varicocele repair (VR) is proposed to improve fertility in subfertile couples with a poor semen quality. We explored whether the disappearance of a left continuous spermatic venous reflux (SVR) at scrotal colour-Doppler ultrasound (CDUS), an objective evidence for a VR, is predictive for improved fertility outcome in subfertile couples. METHODS: VR was performed by left internal spermatic vein sclero-embolisation in 88 males seeking a consultation for subfertility. Semen analysis and scrotal CDUS were evaluated before and 6 months after VR. Serum levels of FSH and total testosterone (TT) were obtained at baseline. Telephone interview was used to obtain information about fertility outcome. Significant predictors of pregnancy and live births, selected by univariate analyses, were included into multiple logistic regression models to assess independent associations. RESULTS: At the adjusted model, independent significant predictors of pregnancy after VR were a disappeared SVR at CDUS (OR = 5.5, 97.5% CI 2.01-15.4; p = 0.0009) and an improved sperm total motile count (TMC) (OR = 5.5, 97.5% CI 1.4-27.9; p = 0.02). Even live births were independently associated with both disappeared left SVR at CDUS (OR = 4.3, 97.5% CI = 1.6-11.8; p = 0.003) and improved TMC after VR (OR = 4.8, 97.5% CI 1.3-24.2; p = 0.02). CONCLUSION: The still controversial effect of varicocele repair on fertility in subfertile couples may reside on the undefined objective methods to document a successful VR and its effect on couple fertility. The disappearance of a continuous left SVR at CDUS after VR was the objective best predictor for subsequent improved fertility in subfertile couples.

RESUMO

BACKGROUND: Varicocele is believed to be a dilated vein of the pampiniform plexus along the spermatic cord. Surgical treatment should be considered in men with a symptomatic varicocele. To date, microsurgical varicocelectomy is the most effective method among various varicocelectomy techniques, according to the current evidence. This study aimed to evaluate the effectiveness of subinguinal varicocelectomy with intraoperative vascular Doppler for symptomatic varicocele and map the distributional trend of spermatic content simultaneously. METHODS: A total of 24 male patients underwent subinguinal varicocelectomy with intraoperative vascular Doppler ultrasound between March 2016 and October 2017, because of symptomatic varicocele or infertility. The numbers, sizes, and location of spermatic vessels in each site were recorded during operation. The visual analogue scale (VAS) score of scrotal pain was also obtained before and after surgery. RESULTS: The mean number of spermatic veins that were ligated in each spermatic unit was 4.70 (±2.06). The predominant distributional zone of spermatic veins was the medial upper zone on an axial view of the spermatic cord. Fifty-six (44.1%) spermatic veins were found in this zone. Normally, each spermatic cord has 1.33 (±0.61) spermatic arteries. The average VAS score prior to surgery was 1.95 (±0.89) and it decreased to 0.05 (±0.21) after the surgery. Complete resolution of pain was observed in almost all symptomatic patients (95.23%). A significant positive relationship between the number of veins ligated and improvement of VAS score was also noted (p < 0.05). CONCLUSION: Subinguinal varicocelectomy with intraoperative vascular Doppler ultrasound is an effective treatment for symptomatic varicocele. The more the internal spermatic veins are ligated, the more the VAS scores are improved. Determining the distributional trend of spermatic content is of great importance in the prevention of iatrogenic injury to the spermatic vessels and vas deferens.

RESUMO

A spermatic vessel aneurysm is a rare entity, described only a few times in the literature. In most cases, it is caused by trauma or inflammation and appears as a painful mass in the scrotum or the inguinal area. We present a case of a 22-year-old man who came to our Surgical Department with a painful, palpable mass in the right inguinal area. A spermatic vein aneurysm was diagnosed with the use of ultrasonography and it was surgically excised. The findings were confirmed by pathological examination. The patient is well, four months after surgery. A spermatic vessel aneurysm, though rare, should always be included in the differential diagnosis of a scrotal or inguinal mass. The lesion can be cured by surgical resection.

RESUMO

BACKGROUND: Varicocele is known to be associated with infertility and sperm disorders. The exact cause of this ailment is not fully understood. There are limited numbers of studies where venous blood gases (VBGs) of varicocele veins were determined with conflicting results. Therefore, we have investigated the pattern of VBGs in both internal spermatic and external spermatic varicocele veins and correlation with semen quality parameters in infertile individuals who underwent left microsurgical varicocelectomy. METHODS: Patients (n = 27) undergoing left microsurgical varicocelectomy at a tertiary care hospital, were included in the study. Before surgery, semen parameters and scrotal color Doppler ultrasonography was performed. During surgery, blood sample was drawn from varicocele veins (internal spermatic and external spermatic veins) and a peripheral arm vein of the same patient as a control. The VBGs of all veins under study were estimated and compared with each other. The VBGs were also correlated with various semen quality parameters. Data, expressed as Mean ± SD, regarding VBGs in three veins were analyzed using one-way ANOVA. The correlation between VBGs and semen quality parameters was determined using Pearson's correlation. Differences were considered significant at p < 0.05. RESULTS: The pH was found to be higher (p < 0.01) in the internal spermatic vein compared with the external spermatic and the peripheral veins. Partial pressure of oxygen (pO2) and oxygen saturation (sO2) were higher (p < 0.01) in the internal spermatic vein compared with the peripheral vein. However, concentration of bicarbonate (HCO3) was lower (p < 0.01) in both veins compared with the peripheral vein. Partial pressure of carbon dioxide (pCO2) was also lower (p < 0.01) in the varicocele veins compared with the control vein. CONCLUSION: The internal spermatic veins had higher pH and oxygen tension, but lower HCO3 and pCO2 levels compared with the control peripheral veins. External spermatic veins had lower pCO2 and HCO3 but other VBGs were similar to the peripheral veins. The shift of VBGs of internal spermatic vein toward arterial blood pattern may be a missing link to understand the pathophysiology of varicocele.

RESUMO

Varicocele is a common abnormality, but the conventional microsurgical subinguinal varicocelectomy (CMSV) has some disadvantages. We invented Modified Inguinal Microscope-Assisted Varicocelectomy (MIMV) under local anesthesia. This study aims to evaluate MIMV by comparing it to CMSV in operating duration, time to return to normal activity, postoperative complications, achievement of natural pregnancy and improvement of semen quality for patients with infertility, pain score for those with scrotal pain, and so on. We enrolled 3089 patients who underwent MIMV and 476 who underwent CMSV in our hospital. Both the operating duration and the time to return to normal activity of MIMV was shorter than that of CMSV (P < 0.001). The recurrence rate (P < 0.001) and injury rate of vas deferens (P = 0.011) after MIMV were lower than that after CMSV. Moreover, patients with MIMV showed higher degree of satisfaction with the surgery experience and outcome than those with CMSV (P < 0.001). However, no statistical difference was found between the two groups in scores of pain due to surgery, postoperative varicose veins diameters, reflux duration, and the postoperative complications of wound infection, hydrocele, atrophy of testis, epididymitis, and scrotal hematoma. In summary, MIMV is a promising varicocelectomy and could be applied more in clinical practice.

RESUMO

PURPOSE: Compare testicular perfusion between the herniated and the healthy side pre- and post-surgery. MATERIALS AND METHODS: Our study was done on patients with unilateral inguinal hernia. A Doppler ultrasound study was performed in the healthy and herniated side before surgery and 3 months after it. RESULTS: 31 patients were included, 74.2% on the right and 25.8% on the left side. When comparing the pre-surgical values of testicular resistance index from the healthy side with those on the herniated side, there was a significant difference at the spermatic cord levels (0.73 ± 0.11 and 0.81 ± 0.13, p = 0.018) and the extra-testicular level (0.66 ± 0.92 and 0.74 ± 0.10, p = 0.032), but a significant difference was not present at the intra-testicular level (0.62 ± 0.07 and 0.65 ± 0.08). Three months after the surgery, there were no statistically significant differences at any of the levels studied. CONCLUSION: There are no intra-testicular perfusion differences caused by the presence of hernia, nor during post-surgery.

RESUMO

PURPOSE: The purpose of this study is to compare the effect of bilateral versus unilateral varicocelectomy on seminal response and spontaneous pregnancy rates in infertile male patients with left clinical and right subclinical varicocele. METHODS: A total of 358 infertile men with left clinical and right subclinical varicocele were randomized to group that underwent bilateral (n = 179) and group that underwent unilateral microsurgical subinguinal varicocelectomy (n = 179). Baseline data regarding male age, female partner age, grade of varicocele body mass index, bilateral testicular volume and serum follicle-stimulating hormone, luteinizing hormone, total testosterone levels and infertility duration and semen parameters were gathered. One year after the surgery, semen parameters including sperm volume, sperm concentration, normal sperm morphology, progressive motility and sperm DNA fragmentation index were recorded and any pregnancy was also documented via telephone calls and hospital visits. RESULTS: We found the baseline characteristics were comparable between the two groups. The seminal parameters had significant improvements 1 year postoperatively in both groups. However, the bilateral group showed significantly greater improvements than the unilateral group in sperm concentration, normal sperm morphology and progressive motility. Besides, the pregnancy rate was statistically higher in the bilateral group after the surgery (42.5 versus 26.0%, bilateral versus unilateral group). CONCLUSION: In conclusion, our study indicated that bilateral is superior to unilateral varicocelectomy in infertile males with left clinical and right subclinical varicocele, which is associated with greater improvements in sperm concentration, normal sperm morphology and progressive motility and spontaneous pregnancy rate after the surgery.

RESUMO

To investigate the clinic value of microsurgical shunt for the treatment of varicocele combined with asthenspermia, the clinical data and therapeutic method for 3 patients, who conducted the microscope spermatic vein high ligation combined with superficial epigastric vein flow, were retrospectively analyzed. No postoperative complications were found, and the original symptoms and signs were disappeared. All patients were conducted scrotal ultrasound and semen routine after 3 months, and all indexes, including maximum internal diameter of the cord vein (erect position), sperm density, sperm survival rate, sperm deformity rate and sperm forward movement rate, were gradually improved. Consequently, high ligation of spermatic vein combined with vascular bypass surgery under the microscope can block the countercurrent venous blood and establish a new return channel to the testis. Meanwhile, it can also protect the testicular artery and lymph-vessel. It is worth to be spread for the treatment of varicocele combined with asthenospermia.

RESUMO

The staging of testicular nonseminomatous germ cell tumors (NSGCTs) with lymphovascular invasion (LVI) of the spermatic cord in the absence of cord parenchymal involvement remains controversial. Our previous study showed that tumors with spermatic cord LVI present at a higher clinical stage than tumors with LVI confined to the testis (pT2). We compared NSGCTs with LVI of the spermatic cord without direct involvement of the spermatic cord soft tissues to pT3 tumors to help clarify the appropriate staging of this histologic finding. A retrospective, multi-institutional review was performed to identify cases of NSGCTs with LVI in the spermatic cord without soft tissue invasion of the cord. The clinical-pathologic findings were compared with NSGCTs with spermatic cord soft tissue invasion (pT3). We identified 38 pT2 NSGCTs with LVI in the spermatic cord without soft tissue invasion of the cord and 89 pT3 tumors. There were no significant differences in patient age, tumor size, or clinical stage at presentation between the 2 groups. There were no significant differences in dominant histologic subtype, rete testis invasion, hilar soft tissue invasion, or margin status. There were no significant differences in disease recurrence/progression (P=0.63), recurrence/progression after chemotherapy (P=0.35), or death (P=0.51) between patients with only spermatic cord LVI versus patients with cord soft tissue invasion. In patients with pT2 NSGCTs according to the current staging, LVI in the spermatic cord without cord soft tissue invasion is comparable with pT3 tumors in terms of clinical stage at presentation as well as disease recurrence and survival.
