OUR RETROGRADE INTRARENAL SURGERY EXPERIENCE IN THE TREATMENT OF MULTI-CALICEAL AND MULTIPLE KIDNEY STONES

Abstract

Objective: Multiple kidney stones are seen in 20-25% of the patients. Treatment of multiple kidney stones is challenging. Retrograde intrarenal surgery is used in the treatment of multiple kidney stones. Success is lower than the single stones of the same size. We aimed to report our retrograde intrarenal surgery experience in the treatment of multi-caliceal and multiple kidney stones. 

Material and Methods: After approval of local ethics committee, patient data between 01.01.2014-01.01.2019 were retrospectively analyzed. Patients who had undergone retrograde intrarenal surgery for multi-caliceal and multiple kidney stones were included in our study. Demographic, intraoperative and postoperative data and complications were recorded.

Results: Forty-three patients were included in our study. The mean stone size was 13.69±6.21 mm. 

Mean stone volume was 972.48 ± 905.24 mm3. Mean Hounsfield unit was 1128.26±317.91 HU. The mean operation time was 51.97±20.18 minutes. Thirty-two patients were stone free. Postoperative complications were seen in four patients. Mucosal injury was observed in one patient and urinary tract infection was observed in three patients.

Conclusion: Multi-caliceal and multiple kidney stone treatment is challenging for urologists. There are various treatment methods. Retrograde intrarenal surgery is a safe and efficient alternative for the treatment of multi-caliceal and multiple kidney stones. Prospective and larger cohort studies are needed.

Multikalisiyel ve Multiple Böbrek Taşlarının Tedavisinde Retrograd İntrarenal Cerrahi Deneyimimiz

Abstract

Amaç: Multiple böbrek taşları % 20-25 hastada görülmektedir. Tedavisi zordur. Retrograd intrarenal cerrahi multiple böbrek taşı tedavisinde kullanılmaktadır. Başarı aynı boyuttaki normal taşlara göre düşüktür. Biz çalışmamızda kliniğimizdeki multiple taş tedavisinde retrograd intrarenal cerrahi deneyimimizi sunmayı amaçladık.

Gereç ve Yöntemler: Lokal etik kurul onayı alındıktan sonra 01.01.2014-01.01.2019 arası hasta verileri retrospektif olarak tarandı. Multikaliseal ve multiple böbrek taşı için retrograd intrarenal cerrahi yapılan hastalar çalışmaya alındı. Onsekiz yaş altındaki hastalar çalışmadan çıkarıldı. Demografik, intraoperatif, postoperatif veriler ve komplikasyonlar kaydedildi.

Bulgular: Çalışmaya 43 hasta alındı. Taş boyutu ortalama 13.69±6.21 mm idi. Taş volümü ortalama 972.48 ± 905.24 mm3, Hounsfield ünitesi ortalama 1128.26±317.91 HU idi. Ortalama operasyon zamanı 51.97±20.18 dakikaydı. Taşsızlık 32 hastada sağlandı. Postoperatif komplikasyonlar dört hastada görüldü. Bir hastada mukozal yaralanma, üç hastada idrar yolu enfeksiyonu izlendi. 

Sonuç: Multikaliseal ve multiple böbrek taş tedavisi ürologlar için zorludur. Çeşitli tedavi yöntemleri mevcuttur. Retrograd intrarenal cerrahi güvenli ve etkin bir alternatiftir. Prospektif ve yüksek hasta sayılı çalışmalara ihtiyaç vardır.
