Abstract

Objective: To evaluate the feasibility, perioperative outcomes, and short- to mid-term success of robot-assisted laparoscopic pyeloplasty (RALP) in adult patients with ureteropelvic junction (UPJ) obstruction. Materials and Methods: Adult patients who underwent RALP for primary UPJ obstruction at a single center between January 2019 and June 2025 were retrospectively analyzed. The diagnosis was functionally confirmed by evaluating drainage parameters (T½) on diuretic renography (DTPA or MAG-3), following the demonstration of anatomical findings consistent with ureteropelvic junction obstruction on CT or MR urography. All cases underwent transperitoneal RALP using the Anderson–Hynes technique. In selected cases, intravenous indocyanine green (ICG) with near-infrared fluorescence (NIRF) was used for vascular/perfusion assessment. Demographic, operative, and follow-up data were recorded. Results: Eighteen patients were included (age 38.9 ± 15.9 years; female/male = 9/9). Obstruction was right-sided in 8 and left-sided in 10; 12 patients were symptomatic and 6 were diagnosed incidentally. A crossing aberrant vessel was identified in 7 patients; intraoperative ICG was used in 6. Mean operative time was 135.3 ± 20.0 min (console 105.6 ± 15.5), anastomosis time 18.2 ± 3.4 min, estimated blood loss 24.2 ± 9.6 mL, and length of stay 3.4 ± 0.9 days. No statistically significant differences were observed between ICG-assisted and non-ICG patients in terms of operative time, length of hospital stay, or functional improvement. No conversions or transfusions were required; no Clavien–Dindo ≥II complications occurred. The Foley catheter was removed on postoperative day 1 and the drain on day 2. Over a mean follow-up of 30.6 ± 21.4 months, postoperative T½ values decreased to below 20 minutes in all patients, and no recurrence or need for re-intervention was observed. Conclusions: RALP is a safe, effective, and highly feasible option for primary UPJ obstruction in adults. Low morbidity, absence of conversion, and consistent functional/anatomic improvement support its clinical value when performed by experienced teams with appropriate patient selection. Selective use of NIRF-ICG may aid intraoperative decision-making—particularly for vascular anatomy and anastomosis/perfusion assessment—and potentially enhance procedural safety.

Özet

Amaç: Erişkin hastalarda üreteropelvik bileşke (UPB) darlığının tedavisinde robot yardımlı laparoskopik piyeloplastinin (RYLP) uygulanabilirliğini, perioperatif sonuçlarını ve kısa-orta dönem başarısını değerlendirmek. Gereç ve Yöntemler: Ocak 2019–Haziran 2025 tarihleri arasında tek merkezde primer UPB darlığı nedeniyle RYLP uygulanan erişkin hastalar retrospektif olarak incelendi. Tanı, BT/MR ürografide üreteropelvik bileşke darlığı ile uyumlu anatomik bulguların gösterilmesini takiben, diüretikli renografide (DTPA veya MAG-3) drenaj parametrelerinin (T½) değerlendirilmesi ile fonksiyonel olarak doğrulandı. Tüm olgularda Anderson–Hynes tekniğiyle transperitoneal RYLP yapıldı. Seçilmiş olgularda damar/perfüzyon değerlendirmesi için near-infrared floresan (NIRF) modu ile intravenöz indosiyanin yeşili (ICG) kullanıldı. Bulgular: Toplam 18 hasta dâhil edildi (yaş 38.9 ± 15.9 yıl). Darlık sağda 8, solda 10 olguda izlendi; 12 hastada semptomatik, 6’sında insidental tanı mevcuttu. Çaprazlayan aberan damar 7 hastada saptandı ve bu hastaların 6’sına intraoperatif NIRF-ICG kullanıldı. Ortalama operasyon süresi 135.3 ± 20.0 dk (konsol 105.6 ± 15.5), anastomoz süresi 18.2 ± 3.4 dk, tahmini kan kaybı 24.2 ± 9.6 mL ve hastanede kalış 3.4 ± 0.9 gündü. NIRF-ICG kullanılan ve kullanılmayan hastalar arasında ameliyat süresi, hastanede kalış süresi ve fonksiyonel iyileşme açısından istatistiksel olarak anlamlı fark saptanmadı. Konversiyon ve kan transfüzyonu gereksinimi olmadı; Clavien–Dindo ≥II komplikasyon kaydedilmedi. Ortalama 30.6 ± 21.4 aylık izlem süresinde, tüm hastalarda postoperatif T½ değerlerinin 20 dakikanın altına gerilediği ve rekürrens veya yeniden cerrahi gereksinimi izlenmediği saptandı. Sonuç: RYLP, primer UPB darlığı olan erişkinlerde güvenli, etkili ve yüksek uygulanabilirliğe sahip bir seçenektir. Düşük morbidite, konversiyonsuz seyir ve tutarlı fonksiyonel/anatomik düzelme, uygun hasta seçimi ve deneyimli ekiplerle yöntemin klinik değerini arttırmaktadır. Seçilmiş olgularda uygulanan NIRF-ICG, özellikle vasküler anatominin değerlendirilmesinde cerrahi karar verme sürecine katkı sağlayabilir.
