CCONTRALATERAL METACHRONOUS UNDESCENDED
TESTIS: IS IT PREDICTABLE?

PURPOSE
Metachronous undestended tesis (mcUDT), an acquired UDT after contralateral orchiopexy, can
occur in some boys. Our hypothesis was there may be characteristics evident at the time of initial
orchiopexy which could predict the development of contralateral mcUDT.
MATERIAL AND METHODS
We used CPT code for inguinal orchiopexy (54640) to identify all patients with UDT between
1/1997-10/2015. We included patients who underwent orchiopexy for unilateral UDT (uUDT). The
study population were patients who had undergone metachronous orchiopexies, controls were
patients who were 17 years at time of data collection with a single orchiopexy.
RESULTS
From 1035 eligible patients we identified 38 with mcUDT and 207 controls (uUDT). Median age
at the first orchiopexy of mcUDT patients was 2.5 yrs (min/max, 0.50, 10.4) and 8.2 yrs (min/max
0.70, 12.8) for uUDT, p<0.0001. Subjects with a contralateral retractile testis on preoperative exam
had a 4.2 times higher rate of subsequent UDT than patients with a contralateral descended testis
(95% CI [2.077, 8.353]). The rate of mcUDT was 6.7 times higher if the testis was a retractile testis
under anesthesia (95% CI [2.7, 16.5]). No relationship was found for side of initial UDT (p=.4947),
acquired vs. congenital UDT (p=.40), procedure type (p=.52), ipsilateral testicular position (p=.71),
size of ipsilateral UDT (p=.21), and patency of the processus vaginalis (p=.08).
CONCLUSIONS
Patients with a contralateral retractile testis at time of orchiopexy have an increased rate of requiring
a contralateral orchiopexy. A discussion of risks and benefits regarding bilateral orchipexies should
be undertaken with the parents prior to surgery.

KNOWLEDGE, ATTITUDE AND PRACTICE: ANTIBIOTICS

PURPOSE
In our department the diagnosis of acute epididymo-orchitis (EO) is made by ultrasound (US) find-
ings of an enlarged, hypervascular epididymis. The aetiology of EO is not bacterial in the majority
of cases. EAU guidelines state antibiotic treatment is not indicated in most cases unless urinalysis
and culture show bacterial infection. We report our efforts to implement the guidelines within our
department.
