Role of the three-dimensional printing technology incomplex laparoscopic renal surgery: a renal tumor in a horseshoe kidney.

PURPOSE: To report our initial experience using a patient-specific 3D-printed renal tumor model for the surgical planning of a complex heminephrectomy in a horseshoe kidney. MATERIALS AND METHODS: We selected a clinical case for a complex laparoscopic surgery consisting in a 53 year-old male presenting a local recurrence of a renal tumor in a horseshoe kidney with aberrant vascularisation previously treated with a laparoscopic partial nephrectomy. He is now proposed for a laparoscopic left heminephrectomy. Along with conventional imaging, a real-size 3D-printed renal model was used to plan de surgical approach. The perioperative experience of the surgical team was recorded. RESULTS: The surgical team found the patient-specifi c 3D printed model useful for a better understanding of the anatomy and an easier surgical planning. CONCLUSION: The use of patient-specifi c 3D-printed renal models seem to be helpful for the surgical planning in complex renal tumors.

Evidence-based consensus recommendations to improve the quality of life in prostate cancer treatment.

INTRODUCTION: Prostate cancer (PC) is one of the tumours with the highest incidence in recent years. PC therapies have several adverse effects. A panel consensus recommendation has been made to prevent or ameliorate complications in PC treatment to improve quality of life. MATERIAL AND METHODS: Fifteen specialists have met to analyse the different toxicities associated with PC treatment. Each medical specialist performed a National Library of Medicine PubMed search citations searching about these secondary effects and his specialty from 1999 to 2009 to propose measures for their prevention/amelioration. RESULTS: Surgery is associated with incontinence and impotence. Radiotherapy can produce acute, late urological and gastrointestinal toxicity. Brachytherapy can produce acute urinary retention. Chemotherapy is associated with haematotoxicity, peripheral neuropathy and diarrhoea, and hormone therapy can produce osteoporosis, metabolic syndrome, cognitive and muscular alterations, cardiotoxicity, etc. CONCLUSIONS: Improvement in surgical techniques and technology (IMRT/IGRT) can prevent surgical and radiotherapeutic toxicity, respectively. Brachytherapy toxicity can be prevented with precise techniques to preserve the urethra. Chemotherapy toxicity can be prevented with personalized schedules of treatment and close follow-up of iatrogenia and hormone therapy toxicity can be prevented with close follow-up of possible secondary effects.
