Abstract
Introduction

Aimed to investigate the feasibility and availability of fluoroless retrograde intrarenal surgery (fRIRS) in a large patient population.

Methods

Patients who underwent fRIRS for ureteral or renal calculi in our center between June 2019 and June 2024 were reviewed. Demographic data, stone characteristics, operation time, perioperative-postoperative complications, perioperative complications, and stone-free rates of patients who underwent fRIRS for ureteral or renal calculi were evaluated. Claven-Dindo classification was used for complications. All procedures were performed under spinal or general anesthesia.

Results

1079 patients were included in the study. Of the 1079 patients, 352 (32.6%) were female and 727 (67.4%) were male. The mean age was 47.33 ± 14.31 years. The mean size of the stones was 13.1 ± 6.33 mm3. Of the patients, 208 (19.27%) received general anesthesia and 871 (80.73%) received spinal anesthesia. The mean operation time was 37.14 ± 17.65 min. All patients received a Double J (DJ) stent postoperatively. The rate of complications was 8% overall. The complications observed in general were minor; postoperative colic pain and hematuria were observed in 36 (3.3%) patients and 26 (2.4%) patients, respectively. Stone-free rate was 86.4%.

Conclusion

The fRIRS is a safe and feasible method for the treatment of uncomplicated ureteral and renal calculi. In uncomplicated patients, it has similar complication and success rates to conventional methods and eliminates radiation exposure.

Resumen
Introducción

El objetivo es investigar la viabilidad y disponibilidad de la cirugía intrarrenal retrógrada sin flúoroscopia (CRIRsf) en una amplia población de pacientes.

Métodos

Se revisaron los datos de los pacientes sometidos a CRIRsf por litiasis ureteral o renal en nuestro centro entre junio de 2019 y junio de 2024. Se evaluaron los datos demográficos, las características de la litiasis, el tiempo quirúrgico, las complicaciones perioperatorias-postoperatorias, las complicaciones perioperatorias y las tasas libres de litiasis de los pacientes sometidos a CRIRsf para la litiasis ureteral o renal. Para las complicaciones se utilizó la clasificación de Claven-Dindo. Todas las intervenciones se realizaron con anestesia espinal o general.

Resultados

Se incluyeron 1079 pacientes en el estudio. De los 1079 pacientes, 352 (32,6%) eran mujeres y 727 (67,4%) hombres. La edad media era de 47,33 ± 14,31 años. El tamaño litiásico medio era de 13,1 ± 6,33 mm3. Del total de pacientes, 208 (19,27%) recibieron anestesia general y 871 (80,73%) anestesia espinal. El tiempo quirúrgico medio fue de 37,14 ± 17,65 minutos. En todos los pacientes se colocó un catéter Doble J (DJ) postoperatorio. La tasa global de complicaciones fue del 8%. En general, las complicaciones postoperatorias observadas fueron menores; 36 (3,3%) pacientes presentaron dolor cólico y 26 (2,4%) pacientes presentaron hematuria. La tasa libre de litiasis fue del 86,4%.

Conclusiones

La CRIRsf es una técnica segura y viable para el tratamiento de la litiasis ureteral y renal no complicada. En pacientes no complicados, presenta tasas de complicaciones y de éxito similares a las de las técnicas convencionales y evita la exposición a la radiación.
