Robot-assisted radical cystectomy for bladder cancer after low anterior resection: A case report.

Radical cystectomy after low anterior resection is rare, and no cases of robotic surgery have been reported. Cystectomy in patients who have undergone a previous pelvic surgery, whether open or endoscopic, requires caution to avoid damaging other organs due to anatomical changes caused by adhesions in a limited space. Additionally, the curative nature of the treatment must be maintained. We describe a 69-year-old man with a history of open low anterior resection for rectal cancer who underwent robot-assisted radical cystectomy with extracorporeal ileal conduit construction. Although this procedure is challenging, it was performed safely with the collaboration of colorectal surgeons. The patient was discharged without perioperative complications and remained recurrence-free for 5 years.

Association between voiding lower urinary tract symptoms and findings on dynamic magnetic resonance imaging with regard to pelvic organs and their supportive structures.

OBJECTIVES: Pelvic organ prolapse (POP) causes voiding lower urinary tract symptoms (vLUTS). In the present study, we investigated the association between vLUTS and pelvic organ mobility (POM), including relevant supportive structures, on dynamic magnetic resonance imaging (dMRI). METHODS: We included 118 patients who had POP of stage II or less before straining and stage III or more when straining during dMRI. The presence of vLUTS and overactive bladder (OAB) was determined by a voiding subscore of the International Prostate Symptom Score (vIPSS) ≥5 and the OAB symptom score, respectively. POM was measured by dMRI before and during straining, and patients with and without vLUTS as well as patients with and without vLUTS and/or OAB were compared. p < .05 was considered to be statistically significant. RESULTS: According to vIPSS, 42 patients (35.6%) had vLUTS. On dMRI, patients with vLUTS showed a significantly more ventral position and/or movement of the bladder and cervix. Moreover, patients with vLUTS and OAB had significantly more ventral movement of the uterine cervix and a larger strain on imaginary uterosacral and cardinal ligaments than those without these symptoms. In addition, patients with vLUTS and OAB had significantly higher vIPSS than those with vLUTS alone. CONCLUSIONS: vLUTS may be associated with the proximity of the bladder and cervix to the pubic bone and consequent compression of the urethra by the prolapsed organs. vLUTS with OAB might indicate more advanced lower urinary tract dysfunction than vLUTS alone.

Age-specific effect of transurethral holmium laser enucleation of the prostate on overactive bladder in men with benign prostatic hyperplasia: An investigation using an overactive bladder symptom score.

OBJECTIVES: To investigate the age-specific effect of transurethral holmium laser enucleation of the prostate (HoLEP) on overactive bladder (OAB). METHODS: A total of 186 consecutive patients who underwent HoLEP were included. They were divided into three groups: patients aged less than 65 years, between 65 and 74, and 75 or older. The OAB symptom score as well as other relevant variables of lower urinary tract symptoms and function were assessed before and 1, 3, 6, and 12 months after surgery. Age-specific prevalence of OAB, the proportion of resolution of OAB, and de novo OAB were evaluated. RESULTS: The mean age of patients was 70.7 years, and the mean total prostate volume was 75.8 ml. The mean OAB symptom scores before surgery of patients aged less than 65 years, between 65 and 74, and 75 or older were 6.0, 5.2, and 5.7, respectively. At 12 months after surgery, the scores for the respective groups had significantly decreased to 2.1, 2.5, and 3.5. The prevalence of OAB based on the score in the respective groups was 45.8%, 56.9%, and 54.0% (p = .6391) preoperatively and 9.1%, 11.3%, and 15.8% at 12 months after the surgery (p = .7613). Of those with preoperative OAB, 75.0%, 79.2%, and 75.0% of the respective groups showed resolution of OAB at 12 months postoperatively (p = .9427). CONCLUSIONS: In candidates for surgical deobstruction of benign prostatic hyperplasia, HoLEP has potential to improve OAB symptoms regardless of age.

Association between overactive bladder and pelvic organ mobility as evaluated by dynamic magnetic resonance imaging.

Overactive bladder (OAB) is a prevalent condition, which negatively impacts patients' quality of life. Pelvic organ prolapse (POP), also prevalent in women, has been recognized as an important etiology of female OAB, although the pathophysiological mechanisms remain controversial. In this study, we reviewed findings of dynamic magnetic resonance imaging (dMRI) in 118 patients with POP and investigated the association between dMRI findings, including positions and mobilities of pelvic organs as well as parameters of pelvic organ support and bladder outlet obstruction (urethral kinking), and OAB in order to elucidate the pathophysiology of OAB in patients with POP. Our results showed that compared with non-OAB patients, OAB patients had a significantly higher body mass index, more severe pelvic floor muscle impairment, and more profound supportive defects in the uterine cervix (apical compartment). On the other hand, dMRI parameters showed hardly any significant difference between patients with mild and moderate to severe OAB. These findings may imply that levator ani impairment and defective supports of the apical compartment could be associated with the presence of OAB and that the severity of OAB could be affected by factors other than those related to pelvic organ mobility and support or urethral kinking.
