ObjectiveTo compare the clinical effects and postoperative complications of microsurgical subinguinal varicocelectomy (MSV) with or without delivery of the testis and ligation of gubernacular veins in the treatment of varicocele.

METHODSWe retrospectively analyzed the clinical data about 163 varicocele patients treated by MSV, 40 with (group A) and the other 123 without delivery of the testis and ligation of gubernacular veins (group B). We compared the operation time, postoperative complications, rate of recurrence, and semen parameters before and at 3 months after surgery between the two groups of patients.

RESULTSThe operation time was significantly longer in group A than in B (［81.1 ± 20.0］ vs ［62.3 ± 9.6］ min, P = 0.041). Sperm concentration, total sperm count per ejaculate, sperm viability, and the percentage of progressively motile sperm were significantly improved in both groups at 3 months after MSV as compared with the baseline (P < 0.05). There were no statistically significant differences in the above semen parameters between the two groups of patients with grade Ⅲ varicocele before and after surgery (P < 0.05). Scrotal edema developed in 5 cases in group A and wound infection in 2 cases in group B after MSV, but no postoperative testicular atrophy or recurrence was observed in either of the two groups.

CONCLUSIONSMSV with delivery of the testis and ligation of gubernacular veins showed no advantages over that without in reducing varicocele recurrence and improving semen parameters, but rather involved longer operation time and a higher incidence rate of postoperative complications.

Objective: To investigate the effect of laparoscopic extraperitoneal (LSEP) high ligation of the spermatic vein in the treatment of varicocele. METHODS: We retrospectively analyzed the clinical data about 80 cases of varieocele, 48 treated by LSEP and the other 32 by laparoscopic transabdominal retroperitoneal (LSTR) high ligation of the spermatic vein. We recorded the semen parameters before and at 1, 3 and 6 months after surgery, intraoperative blood loss, operation time, postoperative complications, time of gastrointestinal function recovery and rate of pregnancy, followed by comparison of the data obtained between the two groups of patients. RESULTS: Semen parameters were remarkably improved in both the LSEP and LSTR groups of patients postoperatively as compared with the baseline (P <0.05), but with no statistically significant difference at different postoperative months (P >0.05). The intraoperative blood loss was less in the LSEP than in the LSTR group (［8.3 ± 5.2］ vs ［9.1 ± 6.1］ ml, P >0.05), the operation time was shorter in the former than in the latter (［38.27 ± 9.23］ vs ［43.46 ± 11.72］ min, P >0.05), and so was the time of gastrointestinal function recovery (［1.27 ± 0.26］ vs ［2.43 ± 0.41］ d, P <0.05). No statistically significant differences were observed between the two groups during the 6- to 18-month follow-up in the rates of postoperative subcutaneous hematoma, scrotal and subcutaneous emphysema, recurrence, or pregnancy (P >0.05). CONCLUSIONS Laparoscopic extraperitoneal high ligation of the spermatic vein is safe and effective and has the advantage of quick recovery in the treatment of varicocele.

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.

Objective: To investigate the clinical effect of microscopic spermatic vein ligation in the treatment of nutcracker phenomenon (NCP) complicated with left varicocele (VC). METHODS: This retrospective study included 31 cases of NCP complicated with left VC treated in our hospital by subinguinal microscopic ligation of the left spermatic vein (group A, n = 11), open retroperitoneal high ligation of the left spermatic vein (group B, n = 11), or conservative therapy (group C, n = 9). The patients were followed up for 6－24 (15.3 ± 5.4) months. We compared the semen parameters, spermatic vein diameter, left testis volume, and recurrence rate among the three groups of patients before and after treatment. RESULTS: Compared with the baseline, the semen quality parameters were significantly improved in both groups A and B at 6 months after treatment (P<0.05) but reduced in group C (P<0.05); the spermatic vein diameter at rest and that at Valsalva maneuver were markedly decreased in groups A (［2.53 ± 0.27］ vs ［1.84 ± 0.22］ and ［3.53 ± 0.19］ vs ［2.16 ± 0.25］ mm, P<0.05) and B (［2.62 ± 0.33］ vs ［2.15 ± 0.43］ and ［3.36 ± 0.25］ vs ［2.44 ± 0.27］ mm, P<0.05) but increased in group C (［2.56 ± 0.28］ vs ［2.94 ± 0.24］ and ［3.33 ± 0.21］ vs ［3.77 ± 0.26］ mm, P<0.05). No statistically significant differences were found in the left testis volume at 6 months after treatment in group A (［9.85 ± 1.86］ vs ［10.27 ± 1.18］ ml, P>0.05), B (［9.77 ± 2.03］ vs ［9.96 ± 1.72］ ml, P>0.05), or C (［9.83 ± 1.59］ vs ［10.48 ± 2.05］ ml, P>0.05), nor in the recurrence rate between groups A and B (P>0.05). CONCLUSIONS Hematuria, proteinuria and other mild symptoms of nutcracker phenomenon complicated with left VC can be treated palliatively by microscopic ligation of the spermatic vein, which can relieve the clinical symptoms, improve the semen quality, and protect the testicular function of the patient.

OBJECTIVETo study the impact of left varicocele (VC) and varicocelectomy (VCT) on the apoptosis of spermatogenic cells and the levels of nitrogen monoxidum (NO) and interleukin 1 (IL-1) in the rat testis.

METHODSWe randomly divided 60 adolescent male SD rats into four groups of equal number: sham operation control, VC model 1 (VC1), VC model 2 (VC2), and VCT. We determined the semen quality and levels of NO and IL-1 in the testis tissue, detected the apoptosis of spermatogenic cells by TUNEL, and compared the indexes obtained among different groups.

RESULTSAn experimental VC model was successfully established by partially ligating the left renal vein of the rats. Sperm concentration and motility were significantly decreased in the VC1 ([1.54 ± 1.16] x 10⁶/ml and [44.23 ± 15.46]%) as compared with those in the sham operation group ([2.80 ± 1.62] x 10⁶/ml and [72.34 ± 12.62]%) (P < 0.05), but remarkably higher in the VCT ([1.82 ± 1.34] x 10⁶/mI and [51.21 ± 12.62]%) than in the VC2 group ([1.04 ± 1.21] x 10⁶/ml and [39.23 ± 13.21]%) (P < 0.05). The levels of NO and IL-1 in the left testes were markedly elevated in the VC1 ([0.172 ± 0.030] ng/ml and [1.468 ± 0.080 ] mg/ml) in comparison with those in the sham operation group ([0.134 ± 0.021] ng/ml and [0.782 ± 0.079 ] mg/ml) (P < 0.05), and significantly higher in the VC2 ([0.198 ± 0.020] ng/ml and [1.994 ± 0.090] mg/ml) than in the VCT group ([0.141 ± 0.010] ng/ml and [0.781 ± 0.036] mg/ml) (P < 0.05). However, the NO and IL-1 levels in the right testis showed no statistically significant differences between the two groups, and the two levels were positively correlated (r = 0.492, P < 0.01). The rats of the VC1 group exhibited remarkable apoptosis of spermatogenic cells in the bilateral testes, with significant differences in the apoptosis index ( AL) between the two sides (P < 0.05) as well as in the same side in comparison with the sham operation group (P < 0.01). The Als of spermatogenic cells in the bilateral testes showed statistically significant differences in the VCT (P < 0.05) but not in the VC2 group (P > 0.05), and those in the same side manifested dramatic differences between the VCT and VC2 groups (P < 0.01).

CONCLUSIONVaricocele induces changes of the NO and IL-1 levels in the testis tissue and increases the apoptosis of spermatogenic cells, which might be one of the causes of testis damage and spermatogenic dysfunction.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.

METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.

RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).

CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.

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.

OBJECTIVETo evaluate the postoperative complications of microscopic and conventional Palomo varicocelectomy in the treatment of varicocele in army personnel.

METHODSA total of 260 army personnel with varicocele were randomized to receive microscopic varicocelectomy (group A, n=130) and conventional Palomo varicocelectomy (group B, n=130). The postoperative recurrence and complications (scrotal edema, testicular pain and testicular atrophy) were compared between the two groups.

RESULTSAfter 1 year of follow-up, the recurrence rates in groups A and B were statistically comparable (5.3% vs 3.8%, P>0.05). The incidences of testicular atrophy and scrotal edema were significantly lower in group A than in group B (0.7% vs 3.1%, P<0.05; 3.1% vs 14.6%, P<0.05), and the rate of testicular pain relief was significantly higher in group A (90.7% vs 67.7%, P<0.05).

CONCLUSIONMicroscopic varicocelectomy can be a good choice in the treatment of varicocele in army personnel.

OBJECTIVETo compare the effects and postoperative complications of microscopic varicocelectomy (MV) and laparoscopic varicocelectomy (LV) in the treatment of varicocele.

METHODSWe assigned 72 varicocele patients to two groups of equal number to be treated by MV and LV. We compared the two groups in the semen parameters before and 3 months after surgery, postoperative complications, and pregnancy rates of the patients'wives.

RESULTSThe operative time was significantly longer in the MV than in the LV group (P<0.05). The postoperative hospital stay showed no significant difference between the MV and LV groups ([2.2 +/- 2.7] d vs [2.8 +/- 0.8] d). Sperm concentration, sperm motility and the percentage of grade a + b sperm were significantly increased in both groups after surgery (P<0.05), but with no significant differences between the two. The pregnancy rate was 65.2% in the former and 57.1% in the latter. Postoperative hydrocele occurred in 5 cases in the LV, but none in the MV group. There were no statistically significant differences in recurrence between the two groups (P>0.05).

CONCLUSIONMV is superior to LV for its minimal invasiveness, economical anesthesia, faster recovery and lower rates of postoperative complications and recurrence.
