Selecting patients for embolization of varicoceles based on ultrasonography

The role of scrotal ultrasonography from infancy to puberty

Background

Scrotal ultrasonography is an essential diagnostic tool in daily clinical practice. The availability of new‐generation ultrasound machines characterized by clearly improved image quality, low health cost, and higher patient safety, represents only some characteristics of ultrasound investigation. The usefulness of scrotal ultrasonography is particularly evident in the period of life from infancy to puberty, during which males undergo important morphofunctional changes, and several pathological conditions may occur.

Objectives

This pictorial review primarily aimed to investigate the aspects of ultrasonography related to the normal physiological development of the gonads from mini‐puberty to pubertal onset. This study also aimed to provide an update on the use of ultrasonography in main andrological pathologies that may occur during this period. The conditions that are discussed in depth are: cryptorchidism, inguinoscrotal hernias, and hydrocele in the neonatal phase; acute scrotum, epididymo‐orchitis, and testicular cancers in childhood; and hypogonadism, varicoceles, testicular microlithiasis, and oncohematological pathology in puberty.

Discussion

We provided an ultrasound slant for all the above‐mentioned pathologies while purposely avoiding excessive deepening of the pathogenetic, clinical, and therapeutic aspects. Studying the ultrasound aspects of the gonads also facilitates differential diagnosis between various conditions and represents a good aid in evaluating therapeutic success (e.g., in hypogonadism or postsurgical evaluation of varicoceles and cryptorchidism).

Conclusion

Scrotal ultrasonography is now globally recognized as the necessary completion of clinical–laboratory overview in gonads evaluation. This diagnostic procedure is even more indispensable in the infancy–childhood–puberty period for the evaluation of normal gonadal development as well as diagnosis of other possible diseases.

Analysis of internal spermatic vein embolization through catheter versus laparoscopic high ligation in treatment of left varicocele

OBJECTIVE

Varicocele is a common disease in young and middle-aged men. This study aims to compare the efficacy of internal spermatic vein embolization of left varicocele versus laparoscopic high ligation.

METHODS

From January 2017 to September 2018, a total of 69 varicocele patients were admitted and given the opportunity to choose the treatment option. Among these, 26 patients were treated with sclerosing agent injection, while 43 patients underwent laparoscopic surgery. They were followed up for 12 months after surgery, and the technical success rate, recurrence rate, complication rate, cost, operative time, and hospitalization time with regard to these two methods were analyzed.

RESULTS

All patients completed the medical procedures. There was no recurrence in patients in the sclerotherapy group during the follow-up period; however, the complication rate was 19.2%. Furthermore, the operative time, hospitalization time, and cost of treatment were 31.1 ± 11.1 min, 1.2 ± 0.49 days, and 9613.11 ± 895.97 Yuan, respectively. In the laparoscopic group, 9 patients underwent laparoscopic bilateral high ligation, while 34 patients received treatment on the left side alone. The recurrence rate of left varicocele was 4.7% and the complication rate was 44.2%. Furthermore, the operative time, hospitalization time, and treatment cost were 50.4 ± 14.48 min, 4.0 ± 2.02 days, and 10,948.29 ± 2547.00 Yuan, respectively. Moreover, there were statistically significant differences (P < 0.05) in operative time, hospitalization time, and treatment cost. Patients in the sclerotherapy group had an advantage with respect to the overall complication rate when compared with patients from the laparoscopic group (X² = 4.448, P < 0.05), and there was a statistically significant difference in hydrocele (X² = 4.555, P < 0.05). However, there was no significant difference in the recurrence rate between these two groups (X² = 1.245, P > 0.05).

CONCLUSION

Patients who underwent sclerotherapy showed a higher technical success rate, a lower recurrence rate, fewer complications, and shorter hospitalization time compared to those treated with laparoscopic ligation. Transcatheter sclerosing agent injection may be a preferable treatment option for patients with unilateral varicocele.
