“…8 The ideal puncture should maximize the effectiveness of the procedure in terms of the stone-free rate and minimize the risk of complications. 9 Stone removal depends on adequate puncture, with the preferred site being between the lower edge of the 12th rib and the upper border of the posterior iliac crest. Punctures above the 12th and 11th ribs have a 16-and 46-fold increased risk of intrathoracic complications, respectively, compared with subcostal access.…”

DOI:https://doi.org/10.24245/revmexurol.v78i3.1834Resumen ANTECEDENTES: La nefrolitotomía percutánea (PCNL) se estableció como una opción de tratamiento mínimamente invasiva para los cálculos renales desde la década de 1970, es segura y eficaz (tasas de aclaramiento lítico del 78 hasta 95%). La punción ideal debe maximizar la efectividad del procedimiento en términos de tasa libre de cálclulos renales y minimizar el riesgo de complicaciones.CASO CLÍNICO: Paciente masculino de 36 años de edad con dolor lumbar bilateral. En la urotomografía se apreció litiasis bilateral, la derecha compatible con un lito coraliforme incompleto y un colon retrorrenal derecho. Primero se practicó nefrolitotricia flexible izquierda y posteriormente nefrolitotomía percutánea derecha. Se efectuó una punción bajo guía fluoroscópica apoyada mediante una disección digital de todas las capas de la pared abdominal hasta acceder al retroperitoneo para evitar una lesión colónica y formar un túneal a través del que se logró palpar la unidad renal.CONCLUSIONES: La técnica de punción y dilatación digitalizada ofrece un acceso seguro y efectivo en pacientes con factores de riesgo de complicaciones por cálculos renales.Abstract BACKGROUND: Percutaneous nephrolithotomy (PCNL) was established as a minimally invasive treatment option for kidney stones in the 1970s and is considered a safe and effective procedure, with stone clearance rates of 78-95%. The ideal puncture should maximize the effectiveness of the procedure in terms of stone-free status and minimize the risk of complications. CLINICAL CASE:We present the case of a 36-year-old male patient with bilateral lower back pain. A CT urography scan was performed that revealed bilateral lithiasis. The stone on the right side was consistent with an incomplete staghorn stone and a right retrorenal colon was identified. Left flexible nephrolithotripsy and subsequent right percutaneous nephrolithotomy were performed. A puncture was made under fluoroscopic guidance supported by previous digital dissection of all layers of the abdominal wall until gaining access to the retroperitoneum. Colonic lesion was prevented and a tunnel through which the renal unit could be palpated was formed. CONCLUSIONS:The technique of digital insertion and dissection offers safe access to the renal unit that is useful in patients presenting with risk factors for a potential complication.
