Persistence of uropathogenic Escherichia Coli in the bladders of female patients with sterile urine after antibiotic therapies.

This study aimed to provide evidence of persistent uropathogenic Escherichia coli (UPEC) in female patients with recurrent urinary tract infection (UTI) after antibiotic therapy. We collected biopsies of the bladder, and clean-catch urine samples from 32 women who had episodes of recurrent UTI and were given antibiotic therapy. Urine samples and biopsies were analyzed by conventional bacteriological techniques.

[Application of one-stop diagnosis and treatment plan in percutaneous nephrolithotomy for patients with complex renal calculi].

Objective: To evaluate the safety and efficacy of preoperative computed tomography urography (CTU) three-dimensional reconstruction, intraoperative radiology and ultrasound guidance followed by percutaneous nephrolithotomy (PCNL) in the treatment of complex renal calculi.

Methods: We summarized the clinical data of 210 patients with complex renal calculi treated at our hospital from December 2008 to December 2011 in this retrospective study. In the one-stop diagnosis and treatment group (n = 119), the optimal puncture approach was designed according to CTU imaging and three-dimensional reconstruction.

Urodynamic investigation of cyclophosphamide-induced overactive bladder in conscious rats.

Background: Overactive bladder (OAB) can be caused by many factors such as inflammation, bladder outlet obstruction, neurogenic factors. We performed an intraperitoneal (ip) injection of cyclophosphamide to induce cystitis in rats, which causes their detrusors to overact, to provide a valuable disease model for discussing OAB pathogenesis and to study effective curing methods.

Methods: Female Sprague-Dawley rats were induced to form cystitis by cyclophosphamide (200 mg/kg, ip).

[Endourological treatment of aged high-risk patients with benign prostate hyperplasia: a report of 283 cases].

Objective: To evaluate the safety and effectiveness of endourological techniques in the treatment of benign prostate hyperplasia (BPH) in aged high-risk patients.

Methods: We used endourological techniques in the treatment of 283 BPH patients aged over 70 years and complicated with hydronephrosis, renal failure, heart failure, cerebral infarction, respiratory dysfunction, anemia, diabetes, bladder tumor, or prostate weight over 80 g, TURP (transurethral resection of the prostate) for 112 cases and PKRP (transurethral plasmakinetic resection of the prostate) for the other 171. All the patients were followed up for 1-30 months.

[Clinical significance of parameters of prostate volume measured by transabdominal ultrasonography in evaluating bladder outlet obstruction].

Objective: To explore the correlation between the parameters of prostate volume (PV) measured by transabdominal ultrasonography and urodynamic results in diagnosing bladder outlet obstruction (BOO).

Methods: 112 BPH patients aged 45-85 underwent transabdominal ultrasonography to measure the superior-inferior diameter (R1) anterior-posterior diameter (R2), and left-right diameter (R3). Urodynamic examination was conducted to record the maximum flow rate (Qmax), detrusor pressure at maximum urinary flow rate (Pdet.

[Ureteroscopic holmium: YAG laser lithotripsy for managing urinary tract calculi].

Objective: To evaluate the effectiveness and safety of ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi.

Methods: Ureteroscopic holmium: YAG laser lithotripsy was used in 168 ureteral calculi (proximal 27 cases, middle 33 cases, distal 108 cases). Transurethral cystoscopic holmium: YAG laser lithotripsy in 12 bladder calculi.
