Abstract

Objectives: The aim of this study was to investigate the longitudinal 5‐year long‐term outcomes for urinary continence and quality of life (QOL) after robot‐assisted radical prostatectomy (RARP), particularly nerve‐sparing. Methods: Among patients who underwent RARP between October 2010 and October 2015, postoperative urinary symptoms were retrospectively examined using the International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire‐Short Form (ICIQ‐SF), QOL index, and number of pads used. Patients were divided into nerve‐sparing and non‐nerve‐sparing groups, and all data were evaluated before and at 1, 3, 6, 12, 24, 36, 48, and 60 months after surgery. Results: After propensity score matching, 47 patients each were included in the two groups. No significant difference in the IPSS or QOL index was seen between groups. The IPSS and QOL index showed an increase in the first month after RARP, but at 6 months, values were lower than preoperative levels and then slowly improved. Pad‐free rates at 5 years after surgery were 93.6% and 80.1% in the nerve‐sparing and non‐nerve‐sparing groups, respectively (P =.029). ICIQ‐SF scores were significantly improved in the nerve‐sparing compared with the non‐nerve‐sparing group at 1, 3, and 6 months after surgery. After 12 months, no significant changes were identified until 60 months. Conclusions: In this study, nerve‐sparing had a strong impact on urinary continence in the early postoperative period. After 12 months, urinary continence remained stable until 60 months. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Although robot‐assisted nephroureterectomy (RANU) has been increasingly used worldwide, the history of RANU remains short, and the optimal surgical method for performing RANU has yet to be established. Here we introduce the ideal approach for RANU using the Vessel Sealer Extend (VSE). Materials and Surgical Technique: RANU was performed by using a da Vinci Xi surgical system with fenestrated bipolar forceps (by the left arm), and monopolar scissors or needle drivers (by the right arm), and the VSE (by the third arm). First, nephrectomy and lymphadenectomy were performed at the kidney direction stage, followed by the removal of the distal ureter and suturing of the bladder at the bladder direction stage. The key point of our technique is that the console surgeon can continue to obtain the optimal surgical field by traction using the third arm, and thus cut the tissue by smoothly switching between the right hand and the third arm without the need to exchange instruments, especially in the kidney direction stage. In this study we performed RANU in nine patients and lymphadenectomy in seven patients. The median console time was 195 (range: 165–265) min, the median blood loss was 55 (range: 5–179) ml. In eight cases of RANU using the VSE, no lymphatic leakage was observed and all procedures could be performed safely. Discussion: The use of VSE provides sufficient coagulation and optimal surgical field development, thus allowing console surgeons to perform RANU more safely. [ABSTRACT FROM AUTHOR]

Abstract

Research was conducted to examine the influences of geometrical configuration on AC loss measurement with pickup-coil method. The transverse-field losses were measured in a NbTi multifilamentary wire under different geometrical conditions and geometrical errors were obtained to check the theoretical expression of the geometrical error factor. Some sets of samples and pickup coils were prepared and observed AC losses were compared with the theoretical predictions.

Abstract

The definition of continence after robot-assisted laparoscopic radical prostatectomy (RARP) has not been consistently defined, with many studies only noting the amount of safety pads used. We therefore examined what definition of continence would be appropriate, employing both the International Consultation on Incontinence Modular Questionnaire Short Form (ICIQ-SF) and the number of pads used by patients. We also evaluated the relationship between the number of pads used and degree of incontinence.Patients who underwent RARP between October 2010 and July 2014 in our department were included in the present study. All patients were evaluated by ICIQ-SF and the number of pads used 1, 3, 6 and 12 months after surgery. Frequency of incontinence and amount of incontinence were evaluated by ICIQ-SF Questions 1 and 2 respectively at 12 months. Quality of life (QOL) was evaluated by ICIQ-SF Question 3 at 1, 3, 6, and 12 months after RARP.The overall study population was 156 patients. In Question 1, 19 patients answered that they leaked urine several times a day, but 5 patients did not use pads, and 8 patients were using only 1 pad a day. In Question 2, 8 patients answered that they leaked a moderate amount of urine, but 2 patients did not use any pads, and 3 patients used only 1 pad a day. QOL showed significant differences between using no pad, 1 pad, or ≥ 2 pads at 1, 3, 6, and 12 months after RARP.Simply noting the number of pads used by a patient is an insufficient way to evaluate incontinence after RARP. Assessment by an appropriate questionnaire is also needed.
