Robotic surgery with Da Vinci has revolutionized the treatment of several diseases, including prostate cancer; nevertheless, costs remain the major drawback. Recently, new robotic platforms entered the market aiming to reduce costs and improve the access to robotic surgery. The aim of the study is to compare direct cost for initial hospital stay of radical prostatectomy performed with two different robotic systems, the Da Vinci and the new Hugo RAS system. This is a projection study that applies cost of robotic surgery, derived from a local tender, to the clinical course of robotic radical prostatectomy (RALP) performed with Da Vinci and Hugo RAS. The study was performed in a public referral center for robotic surgery equipped with both systems. The cost of robotic surgery from a local tender were considered and included rent, annual maintenance, and a per-procedure fee covering the setup of four robotic instruments. Those costs were applied to patients who underwent RALP with both systems since November 2022. The primary endpoint is to evaluate direct costs of initial hospital stay for Da Vinci and Hugo RAS, by considering equipment costs (as derived from the tender), and costs of theater and of hospitalization. The direct per-procedure cost is €2,246.31 for a Da Vinci procedure and €1995 for a Hugo RALP. In the local setting, Hugo RAS provides 11% of cost saving for RALP. By applying this per-procedure cost to our clinical data, the expenditure for the entire index hospitalization is € 6.7755,1 for Da Vinci and € 6.637,15 for Hugo RALP. The new Hugo RAS system is willing to reduce direct expenditures of robotic surgery for RALP; furthermore, it provides similar peri-operative outcomes compared to the Da Vinci. However, other drivers of costs should be taken into account, such as the duration of OR use—that is more than just console time and may depend on the facility's background and organization. Further variations in direct costs of robotic systems are related to caseload, local agreements and negotiations. Thus, cost comparison of new robotic platform still remains an ongoing issue.

Bartter syndrome with sensorineural deafness (type IV Bartter syndrome) is a subtype of this tubular disease, and is due to mutations in the BSND gene. Out of a population of 92 patients with Bartter syndrome, five suffered from mild to severe hypoacusia and were selected for mutational screening. A homozygous mutation in the BSND gene was found in two female patients. The first patient was found to have a substitution in intron 1 donor splice site at position +5 (c.420+5G>C), whereas the second patient has a homozygous 3G>A substitution leading to the loss of the start codon for the translation of the BSND mRNA. The clinical courses of these two patients were remarkable for severe polyhydramnios, massive renal salt and water wasting, severe neonatal hypotonia, poor growth and unresponsiveness to prostaglandin inhibitors. The diuretic responses to furosemide and to hydrochlorothiazide were tested under KCl supplementation in one patient. A lack of response to both drugs suggested that inhibition of NaCl reabsorption in type IV Bartter syndrome is not restricted to the thick ascending limb of Henle. In one patient, a combined therapy with indomethacin and captopril was needed to discontinue intravenous fluids and improve weight gain. [ABSTRACT FROM AUTHOR]
