Unilateral torsion of the testis was experimentally induced in Sprague-Dowley rats by an incision in the scrotum and manual rotation of the testis. The testes remained torted for 3 or 24 hours and then were released by detorsion or orchiectomy. Histologic changes were evaluated 2 weeks and 4 weeks post torsion episode in order to answer the following questions:(1) Does the duration of testicular torsion affect the degree of histologic change in the contralateral testis? (2) Does the treatment of the torted testis influence the contralateral testis histologically? (3) Are there any histologic differences according to the duration of the follow-up in each group? The results indicate that when a torted testis was kept in place for at least 24 hrs, then was a marked decrease in spermatogenesis, but even this histologic change disappeared 4 weeks later. In conclusion a torted testis may present a liability to the patient's contralateral testis, but this phenomena is temporal.

Schoenlein-Henoch syndrome (SHS), one of the manifestations of systemic vasculitis, usually involves the skin, gastrointestinal tract, joints and kidney. Since the involvement of male genitalia is very rare and there is little mention of it in textbooks, doctors have a tendency to neglect this finding in SHS. Unless there is a confirming diagnosis, it is easily mistaken for testicular torsion and the patients undergo unnecessary operations because they complain of unbearable scrotal pain. SHS is not uncommon in Korea, but hardly any cases of scrotal involvement are found. We have experienced 7 cases of acute scrotum associated with SHS admitted to Severance Hospital, Yonsei University College of Medicine during the last 20 years; 2 underwent operation and 5 received conservative treatment only.

Acute scrotal pain (ASP) requiring surgical exploration is common in the pediatric population, but little has been reported on this subject with regard to the adult population. The aim of this study was to investigate the demographic and clinical characteristics and outcomes of scrotal explorations performed on adult patients. Patients over 21 years of age who underwent surgical exploration for ASP with suspected testicular torsion (TT) at 14 French hospitals between January 2005 and December 2019 were included in this study. The main outcome measures were demographic characteristics, pathology found during scrotal exploration, and perioperative outcomes. Logistic regression was used to perform univariate and multivariate analyses to identify predictors of TT. Data for 1329 men were analyzed. The median age was 30 (interquartile range [IQR]: 25-35; range: 21-89) years. Regarding the clinical examination, 867 (65.2%) patients presented with an elevation of the testicle, 613 (46.1%) patients with scrotal edema or erythema, and 211 (15.9%) patients with nausea or vomiting. Operative findings identified TT in only 684 (51.5%) patients, epididymo-orchitis in 112 (8.4%) patients, a tumor in 16 (1.2%) patients, and no causes in 475 (35.7%) patients. Orchiectomy for nonviable testes was required in 101 (7.6%) patients. In multivariate analysis, an elevation of the testicle, erythema/swelling, and the presence of nausea/vomiting were found to be associated with the occurrence of TT. Testicular torsion is not exclusive to children and adolescents, so must be considered in males of any age with acute scrotal findings. However, one-third of scrotal explorations in adults did not lead to a diagnosis.

Testicular torsion has been estimated to affect 1 in every 4 000 males younger than the age of 25 years and has peaks of incidence occurring in the neonate and the adolescent entering puberty. The incidence of missed testicular torsion was about was 4%. The incidence of missed non-simultaneous bilateral torsion was unknown. We presented a case of missed bilateral testicular torsion with resulting primary testicular failure and hypogonadism with erectile dysfunction. The patient was seen for infertility and erectile dysfunction 10 years after the testicular torsion. Semen analysis revealed azoospermia. Serum total testosterone was at the castration level (0.14 nmol/L). His infertility was irreversible. His erectile dysfunction was managed successfully with testosterone replacement and use of sildenafil.

The testicular prosthesis can be an afterthought for providers when performing an orchiectomy for testicular cancer, torsion, atrophic testis, or trauma. However, data suggest that patients find the offer of a testicular prosthesis and counseling regarding placement to be extremely important from both a pragmatic and a psychosocial perspective. Only two-thirds of men undergoing orchiectomy are offered an implant at the time of orchiectomy and of those offered about one-third move forward with prosthesis placement. The relatively low acceptance rate is in stark contrast with high patient satisfaction and low complication rates for those who undergo the procedure. The most common postoperative patient concerns are minor and involve implant positioning, size, and weight. Herein, we provide an up-to-date review of modern preoperative evaluation, patient selection, expectation management, surgical technique, and expected outcomes for testicular prostheses.

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.
