Abstract

Background/aim: The aim of this study was to investigate changes in penile oxygen saturation in Japanese patients before and after robot-assisted radical prostatectomy (RARP).

Patients and methods: The present study included 33 Japanese patients who underwent RARP between June 2018 and February 2024. Tissue oxygen saturation (StO₂) was measured in the glans, bilateral corpora, and both thighs before and after surgery using Toccare™, a tissue oximeter.

Results: Nerve-sparing procedures were achieved as follows: right side, 16 patients (48.5%); left side, 11 (33.3%); bilateral, 4 (12.1%); none, 2 (6.1%). In all patients, no significant difference was observed in StO₂ in the bilateral thighs before and after surgery, whereas a significant decrease was noted in the glans and bilateral corpora after surgery. StO₂ in the glans and bilateral corpora significantly decreased in 20 patients in the right-side nerve-sparing group and 15 in the left-side nerve-sparing group, and nerve-sparing procedures did not correlate with changes in StO₂.

Conclusion: StO₂ in the glans and bilateral corpora decrease after RARP irrespective of whether a nerve-sparing procedure is performed.

日本男性在机器人辅助根治性前列腺切除术前后的阴茎氧饱和度。

背景/目的：本研究的目的是研究机器人辅助根治性前列腺切除术（RARP）前后日本患者阴茎氧饱和度的变化。患者和方法：本研究包括33名日本患者，他们在2018年6月至2024年2月期间接受了RARP。使用组织氧饱和度仪Toccare™测量手术前后的组织氧饱和度（StO2），包括龟头、双侧体和双侧大腿。结果：右侧16例（48.5%）患者行神经保留手术；左侧11例（33.3%）；双侧4例（12.1%）；无，2（6.1%）。在所有患者中，手术前后双侧大腿的StO2无显著差异，而手术后龟头和双侧体的StO2明显降低。右侧神经保留组20例患者和左侧神经保留组15例患者的龟头和双侧体的StO2显著降低，神经保留手术与StO2的变化无关。结论：在RARP后，无论是否进行神经保留手术，龟头和双侧体的StO2均降低。
