OBJECTIVE: To investigate the effect of laparoscopic high ligation of spermatic cord vein in patients with chronic prostatitis and varicocele prostatitis. METHODS: A total of 90 varicocele patients were selected from January 2016 to December 2020, including 33 patients with chronic prostatitis. Changes of white blood cell count, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score and serum testosterone level in the expressed prostate secretion (EPS) were observed before and after the operation of laparoscopic high ligation of spermatic vein. RESULTS: All patients were followed up three months after the surgery. There was no significant difference in the white blood cell counts in EPS, NIH-CPSI score, and serum testosterone level in patients with varicocele-only who underwent high ligation surgery after the operation. However, the white blood cell count in the EPS of patients with chronic prostatitis was lower than that before 3 months of operation ( ［12.39±4.23］×109/L vs ［21.36±5.05］×109/L). The NIH-CPSI score was significantly lower than that before operation ( ［12.71±6.21］ vs ［26.76±8.43］). And the serum testosterone level was higher than that before operation (［4.34±1.77］ng/ml vs ［2.36±1.05］ng/ml). CONCLUSION Laparoscopic high ligation of the spermatic vein in patients with chronic prostatitis and varicocele could effectively reduce the number of white blood cells in the EPS, boost the level of serum testosterone and improves symptoms of chronic prostatitis.

We retrospectively reviewed data for 286 patients with varicocele who underwent microsurgical subinguinal varicocelectomy from March 2015 to May 2017 in Shanghai General Hospital (Shanghai, China). In this surgical approach, the testis was delivered, and the gubernacular and external cremasteric veins were stripped. In addition, the spermatic cord was delivered downward with continuous double traction away from the external ring. The remaining procedure was similar to the conventional approach. We followed patients for at least 3 months and evaluated postoperative semen parameters, pain symptoms, and complications. We excluded data for 32 men due to inadequate follow-up (<3 months). Of the remaining 254 patients, 73 had oligoasthenospermia, 121 had nonobstructive azoospermia, and 60 had symptomatic varicoceles. Total progressive sperm counts increased in the oligoasthenospermic patients from a median preoperative value of 9.15 × 10⁶ ml^-1 to 25.33 × 10⁶ ml^-1 (n= 34), and 35.6% (26/73) initially oligoasthenospermic men contributed to unassisted pregnancies. Sperm returned to the ejaculate in 12.4% (15/121) azoospermia patients. In patients with scrotal pain (n = 60), 43 (71.7%) reported complete resolution of pain, 16 (26.7%) reported partial resolution, and 1 (1.7%) reported no change. No patients experienced varicocele recurrence. This double-traction strategy avoids opening the external oblique aponeurosis, and results in less damage and faster recovery. In addition, the stripping strategy eliminates potential damage to the testis caused by the varicose veins. Our results showed that microsurgical subinguinal varicocelectomy using spermatic cord double traction in conjunction with testicular delivery for vein stripping is a safe and effective approach for varicocele repair.

Objective: To explore the effect of spermatic vein ligation under the microscope in the treatment of varicocele (VC). METHODS: A total of 120 VC patients received in our department from September 2011 to February 2015 were randomly divided into an experimental and a control group of equal number, the former treated by microscopic spermatic vein ligation and the latter by conventional open high ligation. Comparisons were made between the two groups of patients in the internal diameters of the spermatic vein during eupnea and Valsalva maneuver, the reflux time of the spermatic vein, blood flow parameters of the testicular artery, and semen quality before and at 3 months after surgery. RESULTS: At 3 months after surgery, the experimental group, as compared with the control, showed significantly decreased reflux time of the spermatic vein (［0.41 ± 0.10］ vs ［1.08 ± 0.10］ s, P <0.05) and peak systolic velocity (9.26 ± 1.35 vs 10.64 ± 1.28, P <0.05) and resistance index (0.52 ± 0.03 vs 0.61 ± 0.03, P <0.05) of the testicular artery but markedly increased internal diameters of the spermatic vein during eupnea (［1.63 ± 0.07］ vs ［1.59 ± 0.06］ mm, P <0.05) and Valsalva maneuver (［1.72 ± 0.05］ vs ［1.68 ± 0.07］ mm, P <0.05), sperm concentration (［46.84 ± 5.24］ vs ［35.35 ± 4.26］ ×10⁶/ml, P <0.05), sperm motility (［63.75 ± 7.73］ vs ［53.87 ± 6.46］ %, P <0.05), and total sperm count (［89.54 ± 7.95］ vs ［75.24 ± 8.43］ ×10⁶/ml, P <0.05). CONCLUSIONS Microscopic spermatic vein ligation has a definite effect in the treatment of varicocele, which can significantly improve the testicular blood flow and semen quality of the patient.

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.

OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

OBJECTIVETo investigate the protective effect of phosphodiesterase type 5 inhibitors (tadalafil) on the testis following testicular ischemia-reperfusion injury in rats.

METHODSEighty-four healthy adult male SD rats were randomly and equally divided into groups A (sham operation), B (testicular torsion + low-dose tadalafil), C (testicular torsion + high-dose tadalafil), and D (testicular torsion + placebo). Models were established in the latter three groups by 7200 torsion of the right testis for 2 hours. The animals in groups A and B were treated by gavage with tadalafil at the dose of 0. 5 mg per kg per day, those in group C at 2 mg per kg per day, and those in group D with saline at the same dose. After 3, 7, and 14 days of treatment, the torsioned testes were harvested for evaluation of the superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis tissue. The pathological changes in the testis were observed under the light microscope.

RESULTSAt 3, 7, and 14 days, the SOD activity was (254.46 +/- 7.43), (278.49 +/- 8.33), and (317.99 +/- 3.31) nU/mg prot in group B, and (277.12 +/- 8.80), (309.40 +/- 2.14), and (320.39 +/- 4.72) nU/mg prot in group C, all obviously higher than in D ([223.21 +/- 4.65], [231.45 +/- 4.16] and [248.28 +/- 5.74] nU/mg prot), while the MDA content was lower in the former two groups than in the latter. At 3 and 7 days, the SOD activity was significantly higher and the MDA level significantly lower in group C than in B (both P < 0.01) , while at 14 days, neither showed any remarkable differences between the two groups (P > 0.05). No obvious histopathological change was observed in the testis tissue of group A. At 3 and 7 days, pathological examination of the testis tissue revealed significant differences in the number of seminiferous epithelial layers, testicular histological score, and seminiferous tubule diameter in group B (P < 0.01), but the three indexes at 14 days in group B and at 7 days in group C exhibited no remarkable differences from those at 14 days in group A.

CONCLUSIONTadalafil can alleviate testicular ischemia-reperfusion injury following testis torsion/detorsion in a time- and dose-dependent manner.

OBJECTIVETo identify the anatomical variability of the left spermatic vein (LSV) and determine its effect on the induction of experimental left varicocele (ELV) in adolescent rats.

METHODSWe equally randomized 30 adolescent male SD rats to groups A (LSV collaterals fully ligated and the left renal vein constricted), B (only the left renal vein constricted), and C (sham operation), observed the courses of the LSVs and measured their diameters. At 30 days after operation, we analyzed the changes in the left kidneys and the diameters of the LSVs.

RESULTSIrregular collaterals were observed in 90% of the LSVs and no abnormal changes were found in the left kidneys after surgery. The postoperative LSV diameter was remarkably increased in group A as compared with the baseline ([1.47 +/- 0.15 ] vs [0.16 +/- 0.08] mm, P < 0.01), but showed no significant difference in group B ([0.31 +/- 0.49] vs [0.15 +/- 0.07] mm, P > 0.05) and C ([0.17 +/- 0.07] vs [0.16 +/- 0.06] mm, P > 0.05), and it was significantly longer in A than in B (P < 0.01). The success rate of ELV induction was 100% in group A and 10% in group B, but no varicocele was observed in group C.

CONCLUSIONCorrect identification of the anatomical course of the LSV and ligation of its irregular collaterals are essential for the establishment of a stable and consistent ELV model.

OBJECTIVETo study the safety, effectiveness and feasibility of suprapubis-assisted umbilical laparoendoscopic mini-dual-site surgery (SAU-LEMDS) in the treatment of varicocele.

METHODSThis study included 80 varicocele patients aged 24 - 44 (mean 28.5 +/- 2.6) years, 25 cases of grade I, 45 cases of grade II and 10 cases of grade III, 58 cases in the left side, 6 in the right and 16 in both sides, and all with asthenospermia. The patients were treated by SAU-LEMDS under subarachnoid anesthesia combined with general anesthesia in a supine position with a head-down-feet-up slope of 15 degrees. Two 5 mm trocars were inserted bilaterally at the umbilical edge, one with a 5 mm 30 degrees laparoscope placed in it, and another into the abdominal cavity below the pubic hairline with a 5 mm laparoendoscopic clipper placed in it. The operation procedure was similar to that of standard laparoscopic ligation of spermatic veins, with reservation of the spermatic artery and double-ligation of spermatic veins. And the procedure was repeated for the contralateral lesion in the bilateral cases. Postoperative follow-up was conducted for the incidences of orchiatrophy and testicular hydrocele and changes of seminal parameters.

RESULTSAll the operations were successful, with the mean operation time of (10 +/- 5.0) min (range 8 to 25 min) for the unilateral cases and (18 +/- 6.5) min (range 15 to 30 min) for the bilateral cases, the mean blood loss of (1.5 +/- 0.5) ml (range 1 to 2 ml), and the mean postoperative hospital stay of (2 +/- 0.5) d (range 1.5 to 3 d). The patients were followed up for 6 -24 (12 +/- 2.5) months, which showed significant improvement in sperm motility as compared with the baseline ([28.53 +/- 5.21] vs [19.62 +/- 3.56]%, P < 0.05), with 28 cases (35.0%) restored to normal. Recurrence was found in 4 cases (5.0%). Testicular hydrocele occurred in 7 cases (8.75%), but orchiatrophy in none. The scars in the umbilicus and suprapubis were invisible because of the wrinkles and pubic hair.

CONCLUSIONSAU-LEMDS is safe, effective and feasible for the treatment of varicocele. It is superior to umbilical laparoendoscopic single-site surgery (U-LESS) for its less invasiveness, simpler operation, and better cosmetic appearance.

OBJECTIVEBoth microsurgical subinguinal varicocelectomy (MSIV) and microsurgical high inguinal varicocelectomy (MHIV) are recommended for the treatment of varicocele, but they differ in technical complexity. This study aimed to determine the microanatomy of spermatic blood vessels in the two surgical approaches.

METHODSWe recorded the numbers of spermatic veins, arteries and lymphatics in 80 cases of MSIV and 20 cases of MHIV. We also examined the spermatic cords from 10 adult male cadavers by histological staining.

RESULTSThe numbers of medium spermatic veins (2 -5 mm in diameter) were 1.80 +/- 0.83 and 3.98 +/- 1. 99 in MHIV and MSIV, respectively, with significant difference between the two groups (t = -7.536, P < 0.01), and the total numbers of spermatic veins were 6.40 +/- 1.67 and 9.01 +/- 2.70, also with significant difference between the two (t = -4.071, P < 0.01). However, there were no significant differences between MHIV and MSIV in the numbers of small spermatic veins (diameter < or = 2 mm), large spermatic veins (diameter > or = 5 mm), arteries and lymphatics, nor in the numbers of spermatic veins and arteries of the cadavers.

CONCLUSIONThe total number of spermatic veins and the number of medium spermatic veins may be larger in MSIV than in MHIV, but the medium spermatic veins do not increase surgical difficulty, and MSIV is not more complicated than MHIV.

OBJECTIVE: To assess how high ligation of varicocele improves sperm DNA integrity in patients with asthenospermia. METHODS: The DNA fragmentation index (DFI) and semen analysis were conducted in 30 subjects with normal sperm samples, and the parameters were used as references. Fifty-six patients from the Department of Urology of the Second Affiliated Hospital of Chongqing Medical University from April 2009 to April 2011 all signed the informed consent. Semen was collected 1 week before the high ligation of varicocele and 3 months after the surgery. We compared the change of the integrity of sperm DNA and semen. RESULTS: Three months after the high ligation of varicocele, DFI and semen indexes significantly improved (P<0.05), but no significant difference was found between open surgery and laparoscopic surgery, unilateral varicocele and bilateral varicocele and Grade I, Grade II, Grade III varicocele (P>0.05). Six months later, 27 spouses were pregnant out of the 53 surgical patients (50.9%). DFI of the pregnancy group and the non-pregnancy group was (13.90±9.70)% and (20.10±10.27)%, with significant different (P<0.05). CONCLUSION Varicocelectomy can improve the sperm DNA integrity in patients with asthenospermia, whose effect is not related to surgical approach, unilateral or bilateral varicocele or varicocele grade.
