To the Editor,The recent article titled 'Varicocele: Current controversies in pathophysiology and treatment' is another wellpresented, masterly review of the condition, which for so many years has generated much controversy and discussion, amongst urologists and paediatric surgeons alike. 1 Unfortunately, throughout this otherwise exhaustive review, no mention was made of the many issues that are still hotly debated concerning the surgical treatment -the most intriguing aspect from the perspective of your readership. It was just stated that the microsurgical subinguinal or low inguinal open approach is the method of choice as it has the highest (99.5%) success rate and lowest morbidity. Apparently, the categorical conclusion was based on the figures presented in Table 2 of the original article, which was adopted from a text on fertility/infertility published in 1995. In the same comparison table, the failure rate for laparoscopic varicocelectomy was depicted as ?5-15%. Coincidentally, in the same year, I reviewed in a urology journal the success rates of laparoscopic varicocelectomy citing results from six series then available. 2 Four series reported 100% success, whilst the success rates of the remainder were 97.1% and 99%. Of note also is the fact that urological publications in the ensuring years have, again, amply attested to the high success rate (95-100%) of the laparoscopic approach. [3][4][5] The disparity of results in the literature can be explained by many factors, such as variation in the criteria used to define 'success' and difference in outcome parameter(s) analysed: semen characteristics, testicular volume, painful symptoms, grading of varicosity, recurrence or fertility/pregnancy (cannot be 99.5%!).To add to the controversy, there are two additional factors affecting the success rate, namely, the target age group under study and the technical details, for instance, whether the internal spermatic artery is additionally ligated or not. It was the latter issue that has been the focus of lingering dispute, particularly in the management of adolescent varicoceles.In young adolescents it would be more difficult to isolate and preserve the diminutive lymphatics and internal spermatic artery entwined in small, fre-quently adherent venous collaterals, all of which have to be interrupted if recurrence is to be prevented. 2 No wonder then that the reported success rate in most series consisting mainly of paediatric patients and utilising the artery-sparing technique fell far short of the aforementioned 95-100% success rate for adults. 2,6,7 We advocated, therefore, the simpler technique -mass ligation and division of the internal spermatic vascular pedicle -for young adolescents. 2 Our preliminary results did show improvement to 100% success, which is maintained for the 84 varicocelectomies amassed to date. 8 Inevitably, the idea of achieving good results at the expense of the arterial supply has raised concerns about its safety and added fuel to the fire for continuing controversy. 9,10 Sceptics are adama...
