[Causal association between depression and stress urinary incontinence: A two-sample bidirectional Mendelian randomization study].

OBJECTIVE: To investigate the causal correlation between depression and stress urinary incontinence (SUI) using Mendelian randomization (MR) analysis. METHODS: We searched the FinnGen Consortium database for genome-wide association studies (GWAS) on depression and obtained 23 424 case samples and 192 220 control samples, with the GWAS data on SUI provided by the UK Biobank, including 4 340 case samples and 458 670 control samples. We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium (PGC). We employed inverse-variance weighting as the main method for the MR study, and performed sensitivity analysis to verify the accuracy and stability of the findings. RESULTS: Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI (P=0.005), but not SUI with the risk of depression (P=0.927). And analysis of the PGC data verified the correlation of depression with the increased risk of SUI (P=0.043). CONCLUSION: Depression is associated with an increased risk of SUI, while SUI does not increase the risk of depression.

Removal of a Foley catheter misplaced into the ureter by percutaneous puncture: a rare case report.

BACKGROUND: The incidence of aberrant catheterization into a ureter is extremely low, and there is a 20% chance that the balloon cannot be deflated. Regrettably, the mechanism underlying this complication remains unknown. There has been no reported case of a Foley catheter successfully removed from the ureter via percutaneous puncture. CASE PRESENTATION: A 86-year-old man complained of increasing abdominal pain after an 18F Foley catheter was inserted into his urethra. His attending physician attempted but failed to deflate the balloon. A bedside ultrasound and CT scan revealed that the catheter tip was in the right lower ureter. Several measures, including cutting the catheter and inserting a rigid guidewire, were then attempted but failed to deflate the balloon. Finally, the inflated balloon was punctured with a PTC needle under ultrasound-guidance, and the misplaced Foley catheter was removed. Two days after the pelvic drainage tube was removed, the patient was discharged. CONCLUSION: This is the first reported case of a Foley catheter being removed from the ureter via percutaneous puncture. The mechanism by which the balloon is unable to deflate may be related to the passive twist of the catheter. In such a case, an overall assessment of the patient's condition should be performed, and non-invasive to invasive interventions should be phased in.

Fixing tacks induced bladder erosion and recurrent stones following laparoscopic inguinal hernia repair: a case report.

BACKGROUND: Hernia mesh erosion into the urinary bladder is a rare complication of hernioplasty, and mesh immigration is the most probable pathophysiology. There is no report describing mesh erosion induced by fixing tacks in inguinal hernia repair. CASE PRESENTATION: A 37-year-old man was admitted to our hospital with frequency, urgency and odynuria for 3 months. He received open right inguinal hernia repair in September 2014, and right laparoscopic hernioplasty for recurrence of the inguinal hernia in May 2015. In February 2019, he underwent a day-case transurethral cystoscopic operation for urethral and bladder stones. Cystoscopy revealed the existence of bladder stones and part of the eroded mesh on the right anterior wall, for which an open partial cystectomy was performed. The patient was followed up for 3 months postoperatively, during which no further mesh erosion or stone recurrence was detected by cystoscopy. CONCLUSION: This is the first case report describing mesh erosion into the urinary bladder by fixing tacks following laparoscopic inguinal hernia repair. In such a case, the eroded mesh and tacks need to be removed completely, but the effectiveness of a single transurethral procedure needs to be verified in more cases.

Medium-term Clinical Efficacy and Complications of Plasmakinetic Enucleation of the Prostate Versus Transurethral Resection of the Prostate for Benign Prostatic Hyperplasia.

OBJECTIVE: To compare surgical characteristics, clinical efficacy, and complications of plasmakinetic enucleation of the prostate (PKEP) and transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: From January 2015 to May 2018, 370 patients underwent TURP were included into the TURP group. Meanwhile, another 370 patients underwent PKEP (matched by age, prostate volume, and duration of BPH) were included into the PKEP group. Then, the differences of surgical characteristics, clinical efficacy, and complications were compared between the two groups. RESULTS: The operative time, intraoperative irrigation volume, postoperative irrigation time and irrigation volume, drop in hemoglobin, blood transfusion, postoperative catheterization time, and hospital stay of the PKEP group were significantly less than those of the TURP group (P <.05). No significant differences were observed in the resected tissue weight, visual analogue scale score, and total cost of hospitalization (P >.05); The quality of life score of the PKEP group was significantly lower than that of the TURP group (P <.05). No significant differences of maximum flow rate, postvoid residual urine, Serum prostate-specific antigen, international prostate symptom score and International Index of Erectile Function score were observed (P >.05); The incidences of urinary tract irritation, massive hemorrhage, secondary hemorrhage, bladder spasm, clot retention, and retrograde ejaculation of the PKEP group were significantly lower than those of the TURP group (P <.05). CONCLUSION: PKEP and TURP are comparable regarding cost burden and clinical efficacy in medium-term follow-up. However, PKEP should be given a priority for BPH treatment because of less complication rate and better safety profile.

Computed Tomography Angiography and Three-Dimensional Reconstruction of Renal Arteries in Diagnosing the Bleedings After Mini-Percutaneous Nephrolithotomy: A Single-center Experience of 7 Years.

OBJECTIVE: This study aimed to investigate the role of computed tomography angiography (CTA) and three-dimensional (3D) reconstruction of renal arteries in the evaluation of bleeding after mini- percutaneous nephrolithotomy (PCNL). METHODS: Thirty-one consecutive patients with continuous renal hemorrhage after mini-PCNL were enrolled from January 2015 to January 2022. Demographic and clinical data were retrospectively recorded and analyzed. All patients had received CTA evaluation and subsequently digital subtraction angiography (DSA) embolization to manage renal bleeding. CTA and 3D reconstruction of renal arteries were performed using the 320 multi-detector computed tomography technique and the images were evaluated by experienced radiologists. DSA embolization were performed by an interventional radiologist with more than 10 years of experiences. RESULTS: CTA and 3D construction of renal arteries showed 28 cases of vascular lesions (28/31, 90.3%), including 15 cases of pseudoaneurysm (15/28, 53.6%), 9 cases of arteriovenous fistula (9/28, 32.1%), and 4 cases of suspicious bleeding spot (4/28, 14.3%). While DSA revealed 31 cases of vascular lesions (100%), including 15 cases of pseudoaneurysm (15/31, 48.4%), 10 cases of arteriovenous fistula (10/31, 32.3%), 6 cases of bleeding spot and (6/31, 19.4%). The serum creatinine level was elevated slightly before mini-PCNL and after DSA embolization (73.1±18.1 vs 92.1±33.6, P <.01). 15 patients (15/31, 48.4%) required blood transfusion, with mean blood transfusion volume of 700 ml ±660 ml (range, 400 ml-1800 ml). The bleeding was controlled without any further severe complications. CONCLUSION: CTA and 3D reconstruction of renal arteries were safe and effective in diagnosing renal arterial bleedings after mini-PCNL, with a sensitivity of 90.3% and a specificity of 100%.
