Introduction: Tape infection after insertion of tension-free vaginal tape is a well-known but rare complication. We report a patient who experienced a subcutaneous abscess 19 years after the surgery. Case presentation: A 41-year-old woman presented with fever and lower abdominal pain. She had undergone tension-free vaginal tape insertion for stress urinary incontinence 19 years prior. She had asymptomatic dysuria. After an abscess incision and 1-week treatment with antibiotics, she underwent surgery to remove the tape and the abscess without complications. Conclusion: Tension-free Vaginal Tape insertion could be a potential risk of asymptomatic dysuria, resulting in urinary tract infection. In this case, removal of tape was necessary for controlling subcutaneous abscess resulting from the presence of tension-free vaginal tape.

Abstract

Purpose

To retrospectively assess the feasibility, safety, renal function, technique efficacy rate, and survival of patients with clinical T3a renal cell carcinoma (RCC).

Materials and methods

Sixteen cryoablation sessions were performed in 14 patients (10 men; mean age, 69.8 ± 10.5 years; range, 49–90 years) with 14 clear cell T3a RCCs (mean, 3.3 ± 0.9 cm; range, 1.9–5.2 cm). One patient was on dialysis. Transcatheter arterial embolization was performed before cryoablation in 15 sessions. The primary endpoint was the technique efficacy rate. The secondary endpoints included feasibility, safety, renal function, and survival.

Results

Cryoablation was technically successful in all RCC cases. In two RCCs, cryoablation was performed twice because of local tumor progression. No major adverse events were observed. All patients were alive without metastases, with a median follow-up of 45 months (6−93 months). Complete response was achieved by cryoablation in 11 RCCs (78.6%). The primary and secondary technique efficacy rates were 77.1% and 84.4% at 1 year, 57.9% and 73.9% at 3 years, and 57.9% and 73.9% at 5 years, respectively. One patient underwent dialysis given a total contralateral nephrectomy due to another RCC 1 month after initial cryoablation and a total ipsilateral nephrectomy 46 months after initial cryoablation due to local progression. Except for two dialysis patients, of the 12 patients with a median follow-up of 41 months (6–93 months), none were on dialysis.

Conclusion

Cryoablation was safe and effective in T3a RCC, which mainly involved the renal venous branches and may represent an alternative treatment for inoperable patients.

PURPOSE: To retrospectively evaluate and correlate the contrast-enhanced computed tomography (CECT) and non-enhanced magnetic resonance imaging (MRI) during the early period following renal cryoablation. MATERIALS AND METHODS: Both dynamic CECT and non-enhanced MRI were performed within 4 days following cryoablation in 34 renal tumors in 33 patients. The renal volumes of the unenhanced regions on dynamic CECT (nephrogenic phase, 4 mm thickness) and the regions with signal intensity changes on non-enhanced MRI (fat-suppressed T2-weighted image, 4 mm thickness) were evaluated. Fusion images of the axial, coronal, and sagittal sections of CECT and MRI images were created from the maximum cross-section of the renal tumor, and the match score of each image was visually evaluated on a 5-point scale. RESULTS: The mean renal volume of the unenhanced regions on CECT and those with signal intensity changes on non-enhanced MRI following cryoablation were 29.5 ± 19.9 cm3 (range, 4.3-97.4 cm3) and 30.7 ± 19.8 cm3 (range, 6.7-94.0 cm3), respectively; the difference between them was -1.17 cm3 (95% confidence interval [CI] -2.74, 0.40, P = 0.139). The Pearson's product-moment correlation coefficient (r = 0.975; 95% CI, 0.951, 0.988; P < 0.0001) showed a strong correlation between the volumes. The average match score between CECT and non-enhanced MRI was as high as 4.5 ± 0.5 points (radiologist 1, 4.3 ± 0.5; radiologist 2, 4.7 ± 0.5). Local tumor control rate was 94.1% (32/34 tumors) and recurrence-free survival rate was 82.0% (95% CI: 64.2%, 91.5%) at 5 years. CONCLUSIONS: The region with signal intensity changes on non-enhanced MRI was strongly correlated with the unenhanced region on CECT during the early period following renal cryoablation.

我々が経験したロボット支援下前立腺全摘除術におけるインシデントを報告する.症例は70歳代男性.手術はda Vinci Xiで行われた.術中,1stポートのインストゥルメントを入れ替えた際に,モノポーラシザースよりチップカバーが外れ,紛失した.腹腔内や術野内外をX線透視も用いて探索するも見つからず,Computed tomographyを施行したところ,1stポート造設部の皮下に迷入していた.その後は手術を再開し,合併症なく終了.チップカバーは画像と同部位の皮下より摘出された.手術映像を見返したところ,チップカバーが適切に装着されておらず,インストゥルメント交換の際にトロッカーが皮下まで抜けていたことが判明した.本件のようなインシデントを予防するためには,チップカバーの適切な装着と,インストゥルメントの正しい手順での交換および交換時の確認が必要である.(著者抄録)

The development of several culture media and the availability to isolate and treat pathogens prior to a surgical procedure give us the ability to minimize treatment-related complications, and ultimately results in better outcomes for patients and avoidance of unwanted post-procedure inpatient admissions. In the last decade, an increasing incidence of multidrug-resistant Escherichia coli, especially extended-spectrum beta-lactamase-producing E. coli and fluoroquinolone-resistant pathogens, has been reported. These resistant species frequently colonize the rectal flora and gain access to the systemic circulation via the rectal plexus following a prostate biopsy. The bacteria can eventually lead to life-threatening complications, which is especially important in high-risk patients with multiple co-morbidities. Previously published studies have focused on the isolation of these pathogens with selective media before an invasive procedure and the potential benefits of incorporating the use of selective media as a mandatory pre-operative step. This preventive measure will allow us to offer a tailored prophylactic treatment that benefits patients and reduces the economic burden for the hospital.
