RESUMEN
OBJECTIVE: To assess the feasibility, safety and precision of organ-based tracking (OBT)-fusion targeted focal microwave ablation (FMA), in patients with low to intermediate risk prostate cancer. PATIENTS AND METHOD: Ten patients with a visible index tumor of Gleason score ≤3+4, largest diameter <20mm were included. Transrectal OBT-fusion targeted FMA was performed using an 18G needle. Primary endpoint was the evidence of complete overlap of the index tumor by ablation zone necrosis on MRI 7 days after ablation. Urinary and sexual function were assessed with IPSS, IIEF5 and MSHQ-EjD-SF. Oncological outcomes were assessed with PSA at 2 and 6 months, and re-biopsy at 6 months. RESULTS: Median [IQR] age was 64.5 [61-72] years and baseline PSA was 5 [4.3-8.1] ng/mL. Seven (70%) and 3 (30%) patients had a low and intermediate risk cancer, respectively. Median largest tumor axis was of 11 [9.0-15.0] mm. Median duration of procedure was of 82 [44-170] min. No patient reported any pain or rectal bleeding, and all 10 patients were discharged the next day. Seven days after ablation, total necrosis of the index tumor on MRI was obtained in eight (80% [95%CI 55%-100%]) patients. One patient was treated with radical prostatectomy. Re-biopsy at 6 months in the other 9 did not show evidence of cancer in 4 patients. IPSS, IIEF-5 and MSHQ-EjD-SF were not statistically different between baseline and 6 months follow up. CONCLUSIONS: OBT-fusion targeted FMA was feasible, precise, and safe in patients with low to intermediate risk localized prostate cancer.

Nephroptosis is a rare syndrome, which affects the right kidney in the majority of cases. In the current report, a case of bilateral nephroptosis with an unusual presentation is presented. We performed bilateral laparoscopic nephropexy using a three-trocar approach. The intervention was successful, with a short operative time and minimal blood loss. The clinical presentation of our patient and the surgical technique for bilateral laparoscopic nephropexy are described.
