PPH-01 versus PPH-03 to perform STARR for the treatment of hemorrhoids associated with large internal rectal prolapse: a prospective multicenter randomized trial.

Purpose: This multicenter randomized study was designed to compare the clinical and functional results of stapled transanal rectal resection (STARR) performed with 2 staplers (PPH-01 vs. PPH-03) in the treatment of hemorrhoidal disease associated with a large internal rectal prolapse.

Methods: From a total of 937 patients, referred for hemorrhoidal disease in the 20 centers involved in the study, 425 (45.

[Preservative surgery of the kidney for haemorrhagic angiomyolipoma: a report of two cases].

Renal angiomyolipomas are very rare benign tumours (3% of renal tumours) that may present as isolated tumours or tumours associated with other pathologies, particularly tuberous sclerosis (40%), neurofibro-matosis, or Sturge-Webers disease. Clinically, renal angiomyolipoma is asymptomatic until the tumour becomes larger than 4 cm, causing urinary symptoms such as pain, infection, and microhaematuria. Rarely, in cases of large hypervascularised lesions, the clinical picture at onset may consist in spontaneous haemorrhage due to vessel rupture.
