[Non-palpable testes: laparoscopic or inguinal approach?]

Twenty per cent of the operated patients suffering from cryptorchidisim show no palpable testis in the physical check-up. The use of a non-palpable testis in the initial stages is considered to be controversial when deciding between a laparascopic or an inguinal approach. Our aim is to compare the results obtained with these two approaches and evaluate which one of them would be the most relevant as an initial option.

We examined the patients who have been subjected to surgical intervention for non-palpable testis in the last three years. We had a sample of 53 patients. Bilateral non-palpable testes were disregarded. In the case of 35 patients the initial approach was through the groins while in 18 of them the approach was laparascopic. Relevant data were recorded, such as the age of the patient, right or left side, surgical findings, need for a laparascopic or groin approach and associated hernia.

The average age of the patients at the time of the surgical treatment was 3.7 years R (1-13 years). 42% of the testes were on the right side and 58% on the left. In an initial stage the inguinal approach was used with 35 patients, 2 of these requiring laparascopic exploration due to a non-concluding check-up; it was concluded that they were 2 cases of anorchia. An initial laparoscopic approach was used with 18 patients. Internal vessels in the canal were found which required an inguinal approach. In 12 patients normal or atrophic testes were observed. Testicular descent was achieved through the groin in 10 of them while in the remaining 2 a combined approach was adopted.

80% of the patients subjected to a first laparoscopic approach needed a groin approach later on. 11% of the patients subjected to a first inguinal approach required laparascopic examination. In view of the results obtained, we conclude that inguinal exploration diminishes the need for second procedures.
