Examination Under Anesthesia: The First Step for a Non-Palpable Testicle

For a non-palpable testicle, the next step after the exam is neither ultrasound nor MRI — it's a new examination performed while the child is under anesthesia, with the muscles relaxed. This short but decisive step often clarifies, on its own, how the surgery will proceed.

Why re-examine while the child is asleep?

What makes examination difficult in an awake child is the cremaster reflex and tension in the abdominal wall. Cold, fear, crying, and touch all pull the testicle upward; a testicle in the inguinal canal can hide beneath a tensed abdominal wall. Anesthesia removes both obstacles at once: the reflex is switched off, and the abdominal wall relaxes.

  • As a result, in a portion of children diagnosed with a non-palpable testicle, the testicle becomes palpable in the groin or near the internal ring once the child is asleep. This proportion varies by center in the literature but is far from small; for these children laparoscopy becomes unnecessary, and the surgery is completed through the standard groin approach.
  • Examination under anesthesia is listed in the guidelines as a mandatory step that must be performed before diagnostic laparoscopy in a non-palpable testicle. It's part of the same session and doesn't require a separate appointment or a separate anesthetic.

How is it done?

After the child is placed under general anesthesia in the operating room, and before surgical preparation begins, both groins and the scrotum are re-examined. The physician strokes down along the inguinal canal starting from the internal ring area, and checks the scrotum as well as possible ectopic sites outside the normal path (the base of the thigh, the perineum, the base of the penis, the opposite half of the scrotum).

  • This examination is usually performed jointly by the two pediatric urologists who will perform the surgery; the shared judgment of two hands is especially valuable for distinguishing a small, soft testicle from a remnant. The size and consistency of the other testicle are also noted again at this time.
  • Whatever is found is recorded: the point where the testicle is felt, how far it can be brought down, and the difference from the other testicle. From there, the path splits in one of two directions depending on the findings.
03

If the testicle is palpable, what happens?

If the testicle can be felt in the groin or near the internal ring, laparoscopy is not needed. The surgery is completed in the same session through the standard approach for a palpable testicle — inguinal orchiopexy: a small incision in the groin, freeing the testicle and its vessels, closing any hernia sac if present, and fixing the testicle in the scrotum without tension.

  • This scenario is the simplest outcome for the family: there's no incision at the navel, surgery time is shorter, and the child usually goes home the same day. However, in the preoperative discussion it's explained from the start that this scenario is 'possible,' not 'certain' — if the testicle isn't palpable, the plan shifts to laparoscopy.
  • If the palpable testicle in the groin is very small and firm, it may be an atrophic remnant (nubbin) rather than a viable testicle; in that case the groin is opened and the tissue is assessed. This distinction can only be made during surgery, by directly seeing the tissue.

If the testicle isn't palpable: moving to laparoscopy

If the testicle still cannot be found under anesthesia, diagnostic laparoscopy (a minimally invasive procedure) is performed in the same session: a thin camera is introduced through the navel to view inside the abdomen. This transition doesn't require waking the child, additional preparation, or new consent — all of these sequential steps have already been explained during the consent discussion.

  • On laparoscopy, one of several patterns may be seen: a testicle inside the abdomen, a 'peeping' testicle sitting at the edge of the internal ring, vessels and cord structures entering the inguinal canal, or vessels that end blindly inside the abdomen (a vanishing testis). Each pattern leads to a different next step, and most are resolved in the same session.
  • This is the essence of our team approach: examination under anesthesia, diagnostic laparoscopy, and descent based on the findings are all completed in the same session, through the joint evaluation of two pediatric urologists. The family hands their child over for anesthesia once, and usually leaves surgery with a clear answer.

For families: what's discussed in the consent conversation?

Because surgery for a non-palpable testicle is a procedure whose outcome cannot be fully known in advance, the consent conversation is longer. Each possible scenario is explained in order, along with what will be done for it; the phrase 'we'll decide based on what we find' is not uncertainty — it's a guideline-based plan.

  • If the testicle is palpable under anesthesia: standard orchiopexy from the groin
  • If not palpable: diagnostic laparoscopy in the same session
  • If a testicle is found inside the abdomen: laparoscopic descent or a staged approach
  • If a remnant or blind-ending vessels are found: removal of the remnant, no further surgery needed

  • Surgery duration varies with the findings: cases that end with only a groin orchiopexy are short, while cases involving laparoscopic descent or a staged approach take longer. An overnight stay is usually not needed, but if the scope of surgery expands, one night of observation may be recommended.
  • The two most important things for a family to know are these: these steps don't add extra risk for the baby, and whatever is found, the child's long-term follow-up continues with the same team through adolescence and into adulthood.

Frequently asked questions
Do we need to come on a separate day for the examination under anesthesia?
No. Examination under anesthesia is the first step of the surgery day; it continues under the same anesthetic with laparoscopy and, if needed, descent. The goal is for the child to be anesthetized only once.
How is a testicle that couldn't be found on examination found under anesthesia?
While awake, the cremaster reflex and abdominal wall tension can hide the testicle. Because anesthesia removes both of these obstacles, a testicle in the inguinal canal becomes palpable. In that case laparoscopy isn't needed, and the surgery is completed through the groin.
What happens if the testicle still can't be found under anesthesia?
Diagnostic laparoscopy is performed in the same session through a thin camera at the navel. One of several patterns is seen — a testicle inside the abdomen, vessels entering the canal, or blind-ending vessels — and the plan already discussed beforehand is followed for each.
How long do these procedures take, and will we need to stay in the hospital?
Duration depends on the findings; cases ending with only a groin orchiopexy are short, while laparoscopic descent takes longer. Most children go home the same day; if the scope of surgery expands, one night of observation may be recommended.

Diagnosis and evaluationDiagnostic LaparoscopyDiagnostic laparoscopy (a minimally invasive procedure) is direct visualization of the inside of the abdomen through a thin camera introduced at the navel, and it's the only method that definitively answers both 'is there a testicle' and 'where' in a non-palpable testicle. This page explains how the procedure is performed and how the plan proceeds for every possible finding.BasicsPalpable and Non-Palpable TesticleIn undescended testicle, all treatment planning starts with a single distinction made at examination: can the testicle be felt or not? A palpable testicle is the most common and most predictable group; for a non-palpable testicle, whether it exists and where it is located is clarified in the operating room, with examination under anesthesia and laparoscopy.Surgery in childrenLaparoscopic OrchiopexyFor a non-palpable testicle, both diagnosis and treatment begin with laparoscopy (a minimally invasive technique). A thin camera inserted through the navel shows whether the testicle exists and where it lies; if the testicle is inside the abdomen and its vessels are long enough, it is brought down into the scrotum with laparoscopic orchiopexy in the same session.Diagnosis and evaluationImaging: How Necessary Are Ultrasound and MRI?A significant number of families come to pediatric urology already holding an ultrasound report. Yet for undescended testicle, ultrasound and MRI are tests the guidelines do not recommend routinely: they don't change the decision for a palpable testicle, and they don't give a reliable answer for a non-palpable one. This page explains why, and the exceptions.
