Management of cryptorchidism: a survey of clinical practice in Italy

<p>Abstract</p> <p>Background</p> <p>An evidence-based Consensus on the treatment of undescended testis (UT) was recently published, recommending to perform orchidopexy between 6 and 12 months of age, or upon diagnosis and to avoid the use of hormones. In Italy, current practices on UT management are little known. Our aim was to describe the current management of UT in a cohort of Italian children in comparison with the Consensus guidelines. As management of retractile testis (RT) differs, RT cases were described separately.</p> <p>Methods</p> <p>Ours is a retrospective, multicenter descriptive study. An online questionnaire was filled in by 140 Italian Family Paediatricians (FP) from <it>Associazione Culturale Pediatri </it>(ACP), a national professional association of FP. The questionnaire requested information on all children with cryptorchidism born between 1/01/2004 and 1/01/2006. Data on 169 children were obtained. Analyses were descriptive.</p> <p>Results</p> <p>Overall 24% of children were diagnosed with RT, 76% with UT. Among the latter, cryptorchidism resolved spontaneously in 10% of cases at a mean age of 21.6 months. Overall 70% of UT cases underwent orchidopexy at a mean age of 22.8 months (SD 10.8, range 1.2-56.4), 13% of whom before 1 year. The intervention was performed by a paediatric surgeon in 90% of cases, with a success rate of 91%. Orchidopexy was the first line treatment in 82% of cases, while preceded by hormonal treatment in the remaining 18%. Hormonal treatment was used as first line therapy in 23% of UT cases with a reported success rate of 25%. Overall, 13 children did not undergo any intervention (mean age at last follow up 39.6 months). We analyzed the data from the 5 Italian Regions with the largest number of children enrolled and found a statistically significant regional difference in the use of hormonal therapy, and in the use of and age at orchidopexy.</p> <p>Conclusions</p> <p>Our study showed an important delay in orchidopexy. A quarter of children with cryptorchidism was treated with hormonal therapy. In line with the Consensus guidelines, surgery was carried out by a paediatric surgeon in the majority of cases, with a high success rate.</p

Early successful orchidopexy does not prevent from developing azoospermia

INTRODUCTION: The incidence of Ad spermatogonia (stem cells for fertility) was assessed in 20 cryptorchid patients, all of whom had a successful orchidopexy in childhood but developed azoospermia following puberty. MATERIALS AND METHODS: From a cohort of 231 patients who had a semen analysis following successful orchidopexy 20 patients (9%) had azoospermia. The patients were classified into 2 groups according to the time of surgery: A = < 21 months of age (n = 5, mean = 10.7 &plusmn; 8.6 months) and B = during childhood (n = 15, mean = 10.1 &plusmn; 3 years). Nine of the 20 patients (45%) had bilateral cryptorchidism: A = 1 and B = 8. Testicular biopsies were performed during orchidopexy and analyzed with semi-thin technique. The number of Ad spermatogonia and entire number of germ cells was determined. The patients' semen analyses were evaluated at least twice; FSH and testosterone plasma values were estimated. RESULTS: In group A, all patients had germ cells at the time of surgery (mean = 1.04 &plusmn; 1.4 germ cells per tubular cross section); only 6 patients in group B (40%) had no germ cells (mean = 0.17 &plusmn; 0.4); A vs. B, p = 0.0133. Importantly, Ad spermatogonia were absent in the entire study population. The plasma FSH of 16 patients (80%) was abnormal [median = 16.35 IU/L (Interquartile range of sample - IQR 9.075-27.85 95% CI, 3-53)] while the plasma testosterone of all the patients was normal. CONCLUSIONS: The most severe cause of infertility in cryptorchid patients cannot be mitigated by an early successful surgery alone

Successful treatment of unilateral cryptorchid boys risking infertility with LH-RH analogue

INTRODUCTION: Infertility is the primary concern for boys with uni- or bilateral undescended testes. An early and seemingly successful orchiopexy does not improve fertility in a substantial number of cryptorchid males. We confirmed that LH-RH analogue (LH-RHa) treatment induces an increase in and maturation of the germ cells; however, it was uncertain if treatment would improve the chance of fertility later in life. MATERIALS AND METHODS: Thirty unilateral cryptorchid boys, with an average age of 3 years at the time of surgery, were included in the study. Testicular biopsy showed that they had impaired testicular maturation and were therefore at high risk for infertility. Fifteen of the 30 unilateral cryptorchid boys were treated with 10 µg LH-RHa (Buserelin) nasal spray, administered on alternate days for a period of 6 months, following orchiopexy. The control group consisted of 15 cryptorchid boys who had been treated by Schoemakers type of orchiopexy, alone. After puberty, the ejaculates of both groups were analyzed. RESULTS: All males in the untreated group were severely oligospermic, with 20% being azoospermic. In contrast, 86% of the treated ex-cryptorchid males had a sperm concentration within the normal range; this was significantly different from the sperm concentration found in the untreated group (p = 0.000008). CONCLUSION: For the first time, we demonstrate that infertility in cryptorchidism can be successfully corrected when suitably treated with a LH-RHa. Sperm parameters normalized following therapy in the majority of cryptorchid males who, untreated, would have remained infertile. This innovative hormonal treatment will have a profound effect on the current recommended surgical treatment of boys with undescended testes
