Prospective Evaluation of Predictors of Testis Atrophy After Surgery for Testis Torsion in Children
Urology, 2018Co-Authors: Gwen M Grimsby, Kunj R Sheth, Melise Keays, Candace F Granberg, Vani S Menon, Daniel Dajusta, Lauren Ostrov, Bruce J Schlomer, Carlos Villanueva, Martinez HillAbstract:Objective To prospectively correlate pain duration, red scrotal skin, ultrasound appearance of Testis, and intraoperative Testis color to future Testis Atrophy after acute testicular torsion. Methods Patients 2 months-18 years old with unilateral acute scrotum were consecutively enrolled in a National Institutes of Health transcutaneous near-infrared spectroscopy study, with a subgroup analysis of the true torsion group. Presence or absence of red scrotal skin, pain duration, testicular heterogeneity on preoperative ultrasound, and intraoperative Testis color based on a novel visual chart 5 minutes after detorsion were recorded. All testes underwent orchiopexy regardless of appearance. Percent volume difference between normal and torsed testicles on follow-up ultrasound was compared between patients with and without risk factors. Results Thirty of 56 patients who had surgical detorsion underwent scrotal ultrasound at a mean of 117 days after surgery. A color of black or hemorrhagic 5 minutes after detorsion, pain duration >12 hours, and heterogeneous parenchyma on preoperative ultrasound were associated with significant Testis volume loss in follow-up compared with normal Testis. All patients with a black or hemorrhagic Testis had >80% volume loss. Erythematous scrotal skin was not significantly associated with smaller affected Testis volume in follow-up. Conclusion Based on the high Atrophy rate, orchiectomy can be considered for testes that are black or hemorrhagic 5 minutes after detorsion. Pain duration >12 hours and parenchymal heterogeneity on preoperative ultrasound were also associated with Testis Atrophy. Red scrotal skin was not a reliable predictor of Atrophy and should not delay exploration.

effect of laparoscopic high ligation of spermatic vein on the function of testicular sperm production
Journal of Modern Urology, 2013Co-Authors: Liu RishenAbstract:Objective To explore the significance of laparoscopic high ligation of spermatic vein in keeping the testicular arteries for the treatment of varicocele.Methods A total of 156 patients with varicocele were randomly divided into group A and B.Patients in group A received laparoscopic high ligation of spermatic vein to reserve the testicular arteries and patients in group B received traditional Palomo operation.The semen quality parameters before and after surgery,and the incidence of postoperative complications of the two groups were compared.Results The surgery time of group A was(32.24±8.35)min,which was significantly shorter than that of group B[(36.45±9.14)min,P0.05].The rates of postoperative scrotum edema(2.67%),epididymitis(4%),and Testis Atrophy(2.67%)of group A were lower than those of group B(P0.05).There was no statistical difference in hospital stay and postoperative recurrence rate(P0.05).The postoperative sperm count and live sperm rate of group A were(43.00+4.3)×106 and(65.00+4.55)%,which were significantly higher than those of group B(P0.05).There was no difference in sperm density and sperm vitality between the two groups(P0.05).Conclusion Reserving testicular arteries in laparoscopic high ligation of spermatic vein can significantly improve the quality of postoperative semen parameters,reducing the incidence of scrotal edema,epididymitis,and testicular Atrophy.
