All extirpative and reconstructive urological procedures have been described in the literature, but LESS partial nephrectomy (PN) is one of the most complex procedures and few studies have been published on this subject.</p> </list-item> <list-item> <p>The study describes a clampless technique for LESS PN, by reducing the blood pressure and increasing the intra‐abdominal pressure of the pneumoperitoneum to 20 mmHg, timed to precisely coincide with excision of the tumour. This technique was found to be safe and feasible in the treatment of low‐risk T1a RCC.</p> </list-item> </list> </p> </sec> <sec id="bju11601-sec-0002" sec-type="section"> <title>Objective</title> <p> <list id="bju11601-list-0001" list-type="bullet"> <list-item> <p>To describe the technique and report the surgical outcomes of clampless laparoendoscopic single‐site (LESS) partial nephrectomy (PN) in the treatment of renal cell carcinoma (RCC) with low PADUA score.</p> </list-item> </list> </p> </sec> <sec id="bju11601-sec-0003" sec-type="section"> <title>Patients and Methods</title> <p> <list id="bju11601-list-0002" list-type="bullet"> <list-item> <p>Clampless LESS PN was performed in 14 patients with cT1a renal tumours.
