N2 - Introduction: The optimal management of a high undescended testicle (UDT) remains debated. When tethering is due to shortened spermatic vessels, a one-stage or two-stage Fowler-Stephens Orchiopexy (FSO) can be performed. Published series suggest a higher success rate with a two-stage FSO, though its superiority has not been ascertained. The authors examine patient and surgical factors associated with success of one-stage FSO and compare our outcomes with the established literature. Methods: We retrospectively reviewed the charts of 43 boys who underwent one-stage FSO for 45 testes from 2003 to 2018 by a single surgeon at our institution. Patient factors, surgical approach, and postoperative results were reviewed. Radiographic success was a testis with intact vascular flow or normal echotexture on scrotal ultrasound. Clinical success was a non-atrophic, intrascrotal testis at postoperative follow-up. Radiographic and clinical success was compared. Data analysis was performed with Fisher's exact test and t-test for categorical and continuous variables respectively. Results: Follow-up (mean 29 months; 0.5 months-14.5 years) was available for 40 patients (42 testes; 21 bilateral, 21 unilateral). Average age at surgery was 21.8 months (4 months–10.4 years). Associated conditions were seen in 14 patients. Twenty-nine patients had postoperative scrotal Doppler ultrasound with radiographic success in 25/29 (86.2%). Overall clinical success was 34/42 (81%) with 4 (9.5%) each of atrophy and ascent. A second surgery to address ascent in four patients allowed correction in three for a success rate of 88%. Radiographic and clinical success was significantly associated (P = 0.01). Clinical success was also significantly associated with inguinal rather than laparoscopic testis mobilization (P = 0.03) but not to patient's age, associated conditions, unilaterality/bilaterality, or pre-operative hypoplasia or location. Greater than 3 years of follow-up was available in 11 (26.2%) cases, of which seven had successful results. All adverse outcomes occurred within 8 months after surgery. Success was otherwise durable. Conclusion: This is the largest series of one-stage FSO to date. The success rate of one-stage FSO in this series matches that published in the literature for two-stage FSO; equal success is achieved with fewer surgeries. Postoperative Doppler ultrasound demonstrating intact vascular flow or normal testis echotexture is significantly associated with clinical success and highlights the utility of postoperative ultrasound in patients with an equivocal exam.[Formula presented]
