“…The decreased flow in the left varicocele recognized in the type 3 time-activity curve may represent influx hypoperfusion and a possible hypoxia of the testis ipsilateral to the varicocele secondary to the relative obstruction of venous outflow (Harris et al, 1980). cases of type 1 time-activity curves, venous return is good and is balanced with inflow from the artery, as in normal individuals, even in the presence of varicocele.…”

“…Type 4 pattern indicates marked retrograde flow from renal vein to varicocele, and is accompanied by venous pooling already in the early phase. The decreased flow in the left varicocele recognized in the type 3 time-activity curve may represent influx hypoperfusion and a possible hypoxia of the testis ipsilateral to the varicocele secondary to the relative obstruction of venous outflow (Harris et al, 1980). Early reflux may have masked the arterial deficit in a number of patients with large varicocele such as those with type 4 timeactivity curves.…”

Sequential scrotal scintigraphy was used to study testicular blood flow in 122 patients with clinically diagnosed varicocele. The sensitivity of scrotal scintigraphy was 91.7 % on the whole sequential images. The late-phase image was superior in sensitivity to that of the early-phase images. The difference in time between the arrival of radioactivity in the iliac artery and in the pampiniform plexus grew shorter with increasing grade of varicocele. Time-activity curves were classified into four patterns. One type (Type 3), which was more frequently observed in grade I1 and grade I11 varicocele than grade I varicocele, showed a decreased arterial perfusion of the left side lesion. It is concluded that scintigraphic analysis using both sequential images and time-activity curves is not only highly representative of the grade of clinically palpable varicocele, but also provides a better understanding of local hemodynamics in the scrotum.Zusammenfassung. Mittels sequentieller Skrotalszintigraphie wurde die testikulare Durchblutung von 122 Patienten mit klinischer Varikozele untersucht. Die Sensitivitat betrug 91,7 % uber die gesamten Sequenzbilder der Skrotalszintigraphie; die Bilder der spateren Phasen zeigten eine groBere Sensitivitat als die der fruheren Phasen. Der Zeitunterschied zwischen dem Auftritt der Aktivitat in der Darmarterie und im Plexus pampiniformis war um so kurzer, je groBer der Grad der Varikozele war. Die Zeitaktivifatskurven wurden in vier Mustern eingestuft; eines davon zeigte einen verringerten ZufluB in den Plexus pampiniformis. Die szintigraphische Analyse mit Darstellung von sequentiellen Bildern und Zeitaktivitatskurven gibt den Grad der klinisch fuhlbaren Varikozele deutlich wieder und erlaubt ein besseres Verstandnis der regionalen Hamodynamik im Skrotum.

“…Beginning in the 1970s, attempts were made to use advanced imaging for the diagnosis of nonpalpable ''subclinical'' varicoceles (2). Radioisotope angiography and spermatic venography were both trialed for the detection of subclinical varicoceles, but these approaches were onerous and invasive (3). After Greenberg et al described use of the Doppler stethoscope for detection of subclinical varicoceles, scrotal ultrasound with Doppler emerged as a popular adjunct diagnostic tool (2).…”

Fertility-enhancing male reproductive surgery: glimpses into the past and thoughts for the future

Over the past few decades, there have been numerous paradigm shifts in male reproductive surgery, resulting from a combination of technologic advancements in both the operating room and the laboratory. The operating microscope transformed the field of male reproductive surgery, enabling novel techniques and higher precision for the treatment of male-factor subfertility. The subsequent widespread adoption of microsurgical approaches was largely responsible for the emergence of a cadre of highly specialized male infertility microsurgeons. The advent and evolution of in vitro fertilization/intracytoplasmic sperm injection was a concurrent story that further revolutionized the field. The ability to achieve fertilization and pregnancy with just a single sperm changed the ways in which male reproductive surgeons could approach a wide range of pathologies from obstructive to nonobstructive causes, culminating in the microdissection testicular sperm extraction procedure for the treatment of nonobstructive azoospermia. Here we review the recent advancements in fertility-enhancing male reproductive surgery for the treatment of four disease processes: varicocele, obstruction of the excurrent ductal system, ejaculatory duct obstruction, and nonobstructive azoospermia. While examining the great strides of the past, we look forward to exciting developments on the horizon. (Fertil Steril Ò 2019;112:426-37. Ó2019 by American Society for Reproductive Medicine.

“…The concept of a possible subclinical varicocele recently has been proposed when evaluation by palpation has been unsuccessful and evidence of a stress pattern is seen on seminal examination. Other techniques available to diagnose the varicocele include the Doppler stethoscope, contact scrotal thermography, 19 blood pooling radioisotopic angiography, 50 and/or spermatic venography. 51,52 These techniques may be of some use in defining poorly palpable lesions; however, convincing data relative to the significance of subclinical varicoceles are not available.…”
