To assess the correlation of the size of undescended testis with its location in children of various age groups, per-operatively.
Cross-sectional study.
Surgical Unit B, National Institute of Child Health, Karachi from February 2004 - November 2005.
Children presenting with undescended testis at surgical outpatient were recruited. Physical examination and relevant investigations (haemoglobin, ultrasound for location and size of testes) were performed. Patients were divided randomly into three age groups, group I (8 months - 2.5 years), group II (2.6 - 8 years), group III (8.1-13 years). At orchiopexy location and size of undescended testis were noted. Patients were further sub-divided into groups according to peroperative location of undescended testis, group A (intra-abdominal), group B (intra-canalicular), group C (distal to superficial inguinal ring - pubic). Where no testis was found, a separate group D was assigned. The size of undescended testis at different locations in various age groups was compared with reference to normal descended testicular size in the respective age group, for statistical significance. ANOVA test was used for intergroup comparison for the size of undescended testis and Student t- test was applied for comparison with reference to normal values of the size of testis.
A total of 102 patients with undescended testis were included in the study. The total number of 107 testicular units were assessed. Group I had 28, group II, 41 and group III, 38 testes. There were 24 intra-abdominal, 68 intra-canalicular and 12 pubic in location. In 3 cases, no testis was found at exploration. We found no statistically significant difference amongst groups (p-value=0.090) between the size of the undescended testis at different peroperative locations. The size of undescended testis grew with the age as undescended testis of larger size were found in older age group as compared to younger age group. By applying Student t-test, we did not find statistically significant difference in relation to the size of undescended testis in various age groups in comparison to the reference of mean volume of normally descended testis in the respective age groups.
Pre-pubertal size of undescended testis does not differ significantly from that of normal reference value of descended testis in relation to age and location. The ultimate size of the testis can only be assessed after puberty whether it is a normally descended or undescended testis.
在手术中评估不同年龄组儿童隐睾大小与其位置的相关性。
横断面研究。
2004年2月至2005年11月，卡拉奇国家儿童健康研究所外科B病房。
招募到外科门诊就诊的隐睾患儿。进行体格检查和相关检查（血红蛋白、睾丸位置和大小的超声检查）。患者被随机分为三个年龄组，I组（8个月至2.5岁），II组（2.6至8岁），III组（8.1至13岁）。在睾丸固定术中记录隐睾的位置和大小。根据隐睾的手术中位置，患者进一步细分为A组（腹腔内）、B组（管内）、C组（腹股沟浅环远端至耻骨）。若未发现睾丸，则单独分为D组。比较不同年龄组中不同位置隐睾的大小与相应年龄组正常下降睾丸大小的差异，以确定统计学意义。采用方差分析对隐睾大小进行组间比较，采用学生t检验与睾丸大小的正常参考值进行比较。
本研究共纳入102例隐睾患者，共评估了107个睾丸单位。I组有28个睾丸，II组有41个，III组有38个。位置上腹腔内有24个，管内有68个，耻骨处有12个。在探查中，有3例未发现睾丸。我们发现在不同手术位置的隐睾大小在组间（p值 = 0.090）没有统计学显著差异。隐睾大小随年龄增长，与较年轻年龄组相比，较年长年龄组中发现的隐睾尺寸更大。通过应用学生t检验，与相应年龄组正常下降睾丸平均体积参考值相比，我们未发现不同年龄组隐睾大小存在统计学显著差异。
青春期前隐睾的大小与下降睾丸的正常参考值在年龄和位置方面没有显著差异。睾丸的最终大小只能在青春期后评估，无论其是正常下降还是未下降的睾丸。
