Proctoscopy following transrectal prostate biopsy can control rectal bleeding after prostate biopsy.

OBJECTIVES: Rectal bleeding is a common complication of transrectal ultrasound-guided prostate biopsy (TRPB). Massive rectal bleeding after TRPB can be life threatening. We initiated proctoscopy after TRPB to clarify the incidence of rectal bleeding and evaluated the usefulness of proctoscopy for controlling bleeding after TRPB. MATERIALS: Two hundred and fifty six patients who underwent TRPB were included in the study. TRPB was performed under local anesthesia. Post-biopsy, we performed a proctoscopy to evaluate the degree of rectal bleeding at four levels (G0, no bleeding; G1, traces; G2, venous bleeding requiring hemostasis; and G3, massive venous bleeding or arterial bleeding). Once the bleeding site on the rectal wall was identified, a gauze tampon was placed at the bleeding site and compressed for a few minutes. A second proctoscopy was performed to confirm complete hemostasis, after which the TRPB was terminated. RESULTS: Proctoscopy revealed that the degree of bleeding was G0 in 27 cases, G1 in 104 cases, G2 in 116 cases, and G3 in nine cases. Rectal bleeding that required hemostasis (G2 and G3) was observed in 125 of 256 cases (48.3%). Among the 125 cases, bleeding was stopped by compression in 121 cases; in the remaining four cases, bleeding continued despite compression and was stopped by suturing of the bleeding site. Suturing was performed by urologists, and none of the 256 patients had problematic posterior hemorrhage. CONCLUSIONS: Proctoscopy enables precise and effective pressure hemostasis. Moreover, suturing hemostasis under direct vision can be performed in cases in which pressure hemostasis is difficult. Continued proctoscopy allays urologists' fear of post-TRPB rectal bleeding.

A case of testicular seminoma with testicular abscess caused by Salmonella saintpaul.

Testicular abscesses are rarer than epididymitis and orchitis. Here, we report a case of testicular seminoma with testicular abscess caused by Salmonella saintpaul. A 41-year-old male was referred for painful enlargement of the right scrotal content and fever for 1 week. With the diagnosis of epididymitis, he was administered levofloxacin (LVFX) but the fever and painful enlargement persisted. Because of the poor response to antimicrobial agents and the undeniable complications of testicular malignancy, radical orchiectomy was performed. The testis was enlarged to 7 cm, weighed approximately 100 g, and was filled with pus. A substantial portion of the tumor was seminoma, and pus culture revealed Salmonella saintpaul. Although testicular tumors are the most common differential diseases for testicular abscess, there are few reports of testicular abscess accompanying testicular tumors. Here, we report a case of testicular seminoma with testicular abscess caused by Salmonella saintpaul.

A Clinical Trial Evaluating the Usefulness of Tailored Antimicrobial Prophylaxis Using Rectal-culture Screening Media Prior to Transrectal Prostate Biopsy: A Multicenter, Randomized Controlled Trial.

The aim of this report is to introduce an on-going, multicenter, randomized controlled trial to evaluate whether tailored antimicrobial prophylaxis guided by rectal culture screening prevents acute bacterial prostatitis following transrectal prostate biopsy (TRPB). Patients will be randomized into an intervention or non-intervention group; tazobactam-piperacillin or levofloxacin will be prophylactically administered according to the results of rectal culture prior to TRPB in the intervention group whereas levofloxacin will be routinely given in the non-intervention group. The primary endpoint is the occurrence rate of acute bacterial prostatitis after TRPB. Recruitment begins in April, 2021 and the target total sample size is 5,100 participants.

Impact of selective media for detecting fluoroquinolone-insusceptible/extended-spectrum beta-lactamase-producing Escherichia coli before transrectal prostate biopsy.

OBJECTIVES: To investigate the prevalence of fluoroquinolone-insusceptible and/or extended-spectrum beta-lactamase-producing Escherichia coli colonizing in the male rectum before transrectal prostate biopsy. METHODS: We carried out a prospective cohort study of men undergoing transrectal prostate biopsy. CHROMagar Orientation originally supplemented with levofloxacin and CHROMagar Orientation/extended-spectrum beta-lactamase were used for detecting fluoroquinolone-insusceptible and extended-spectrum beta-lactamase-producing Escherichia coli. Rectal specimens were collected before prostate biopsy, and the results of cultures in the selective medium were compared with drug susceptibility measured by standard methods. Targeted prophylactic antimicrobials were administered to patients with drug-resistant Escherichia coli and the incidence of postoperative prostatitis was investigated. In the case of prostatitis, pathogens preoperatively isolated from the rectum and those from urine were compared using pulsed-field gel electrophoresis. RESULTS: Rectal colonization of fluoroquinolone-insusceptible or extended-spectrum beta-lactamase-producing Escherichia coli was detected in 217 of 694 (31.3%) and 85 of 640 (13.3%) participants, respectively. The sensitivity and specificity of fluoroquinolone-insusceptible selective media were 96.8% and 88.2%, respectively. A total of 618 participants underwent transrectal prostate biopsy, and postoperative acute prostatitis was observed in four of 618 (0.6%) participants. Escherichia coli strains isolated preoperatively from the rectum and postoperatively from urine were found to be identical. CONCLUSIONS: The present findings showed accuracy and performance of the selective media. Screening cultures before transrectal prostate biopsy using selective media seems to be helpful for guiding antibiotic prophylaxis and thus decreasing the rate of post-biopsy acute prostatitis.

[KIDNEY-SPARING SEGMENTAL URETERECTOMY WITH TRANSURETHRAL BLADDER CUFF EXCISION FOR DISTAL URETERAL CARCINOMA].

(Introduction and objectives) Radical nephroureterectomy with complete distal ureterectomy is the standard therapy for upper tract urothelial malignancy. Segmental ureterectomy with ueteroneocytostomy is an alternative for distal ureteral carcinoma. We describe extravesical complete distal ureterectomy combined by transurethral bladder cuff excision with frozen-section analysis. (Patient and methods) Since December 2008, 11 patients (median age 77 year old, male 10, female 1, right 10, left 1) with solitary distal ureteral carcinoma who had mild hydronephrosis of ipsilateral kidney remaining renal function on enhanced CT. Under general anesthesia, the patient was placed in lithotomy position, rigid cystoscopy was inserted into the bladder. Cold punch biopsy of 4 sites of bladder mucosa 5 mm away from ureteral orifice (12, 3, 6, 9 o'clock) was carried out and sent to frozen-section analysis. Use resectoscopy with needle-type electrode, incise the bladder mucosa along the biopsy sites circumferentially and incise submucosa tissue around the ureteral orifice deeply enough to detach intramural ureter. Then lower abdominal midline incision was made. After entering the retroperitoneal space, the ureter was dissected and ureteral margin was sent to frozen-section analysis. The distal ureter was dissected until the margin of bladder mucosa incised by transurethrally. After ascertainment of no cancer cell in the frozen-section, close the defect in the bladder. Then the ureter was re-implanted into the bladder by extravesical approach. (Results) Median estimate blood loss was 150 ml (40-350 ml) and median operative time was 258 min (170-317 min.). No patients in our series required a blood transfusion. The mean tumor size was 20+/- 4.4 mm. Pathological T stage was Ta 3, T1 3, T2 2 and T3 3. No positive surgical margin was noted. Mean serum creatinine before and 1 month after surgery was 1.05+/- 0.21 mg/dl and 089+/- 0.13 mg/dl. Mean eGFR before and 1 month after surgery was 54.1+/- 11.4 and 63.4+/- 8.4. Median followup was 35 months (range 4 to 93). Although there were two patients who died from distant metastatic disease, no patients have encountered cancer recurrence in the remained ipsilateral upper urinary tract. (Conclusions) Segmental ureterectomy combined by transurethral bladder cuff excision with frozen-section analysis could perform complete resection of distal ureteral carcinoma and preserve ipsilateral renal function. This technique is feasible for patients with distal ureteral carcinoma as an optional treatment. Better preservation of renal function can lead to increased tolerance of cisplatin-based adjuvant or salvage chemotherapy.

[Surveillance of Antimicrobial Resistant Esherichia coli by Rectal Swab Method--Annual Change of Prevalence of Quinolone-resistant and ESBL Producing Strains from 2009 to 2013].

Although most of commonly used antimicrobial agents had been susceptible to Esherichia coli, recently there are a lot of reports concerning about community-acquired infection caused by resistant E. coli. The aim of this study is to define the prevalence of resistant E. coli in normal flora colonization by the rectal swab method. From June 2009 to December 2013, 251 male patients (50-85 year-old, median 68) planned to transrectal prostate biopsy participated in this study. Stools stuck on the glove at the digital examination were provided for culture specimen. Identification of E. coli and determination of MIC was performed by MicroScan WalkAway40plus (Siemens). Isolated E. coli were deemed quinolone-resistant strains when their MIC of levofloxacine was 4 µg/mL or above according to the breakpoint MIC by the CLSI criteria. ESBL producing ability was determined by the double disk method used by CVA contained ESBL definition disc (Eikenkagaku). Of the 251 study patients, 224 patients had positive cultures of E. coli. Twenty-four patients had quinolone-resistant strains and 9 patients had ESBL producing strains. The prevalence of quinolone-resistant strains in 2009, 2010, 2011, 2012 and 2013 were 5.9% (2 out of 34 strains), 13.5% (5 out of 37 strains), 12.5% (4 out of 32 strains), 9.0% (6 out of 67) and 13.0% (7 out of 54 strains), respectively. The prevalence of ESBL producing strains in 2009, 2010, 2011, 2012 and 2013 were 0% (0 out of 34 strains), 5.4% (2 out of 37 strains), 3.1% (1 out of 32 strains), 3.0% (2 out of 67 strains) and 7.4% (4 out of 54 strains), respectively. In 2013, the prevalence of antimicrobial resistant E. coli, both quinolone-resistant and ESBL producing strains, were increasing. We have to pay a close attention to the increase of resistant E. coli.

Recurrent rectal GIST resected successfully after preoperative chemotherapy with imatinib mesylate.

A 60-year-old-man underwent initial resection of a rectal tumor, with a transanal approach, on December 6, 2000. The tumor was diagnosed as a gastrointestinal stromal tumor(GIST) by KIT and CD34 immunohistochemistry. In June 2003, a third recurrence in the rectum was discovered, at the same location as the initial tumor, and he was referred to our hospital. Magnetic resonance imaging (MRI) revealed a tumor 3.0 cm in diameter, compressing the prostate anteriorly. After the oral administration of imatinib mesylate (Gleevec, Glivec) at a dose of 400 mg per day for 3 months, the size of the tumor had decreased to 1.2 cm in diameter. On December 12, 2003, a fourth operation was performed successfully, with a perineal approach, preserving sphincter function. More than 40 months after the fourth operation, neither local recurrence nor distant metastasis was detected. Our strategy of treatment with imatinib allows not only complete excision of the tumor but it also reduces postoperative impediments in patients with recurrent rectal GIST.

Comparison of 25 and 75 mg/day naftopidil for lower urinary tract symptoms associated with benign prostatic hyperplasia: a prospective, randomized controlled study.

BACKGROUND: The present study investigated the efficacy, safety, and utility of starting an alpha(1d)-selective antagonist, naftopidil, at 75 or 25 mg/day in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). METHODS: In this prospective comparative study, the subjects comprised 153 patients with LUTS associated with BPH. Patients were randomized to receive either 25 mg/day (Group LD) or 75 mg/day (Group HD) of naftopidil for 4 weeks. The lower urinary tract disease symptom score (LUTDSS), the International Prostate Symptom Score (IPSS), the Quality of life assessment index, the maximum flow rate (Q(max)), and the residual urine volume were compared between the groups. RESULTS: In both groups, the LUTDSS and the IPSS were significantly improved at the endpoint and no significant intergroup differences were identified. However, the improvement in the Q(max) was significantly better for Group HD than for Group LD. The overall efficacy did not differ significantly between the groups. The degree of improvement in voiding symptoms and LUTDSS among patients with moderate symptoms was significantly greater for Group HD than for Group LD. The frequency of adverse reactions did not differ significantly between the groups. CONCLUSIONS: Starting administration at 75 mg/day rather than 25mg/day is helpful for LUTS associated with BPH for patients with moderate symptoms, particularly in improving voiding symptoms. The 75 mg/day administration was considered to be a recommendable therapeutic dose in some patients.

[Antimicrobial susceptibility of Pseudomonas aeruginosa isolated at Kochi Municipal Central Hospital in the last 3 years].

Antimicrobial susceptibility of Pseudomonas aeruginosa isolated at Kochi Municipal Central Hospital between 2001 and 2003 was assessed according to the NCCLS interpretive criteria. 1. The piperacillin-susceptible rate was 92.9%. 2. Among cephem antibiotics, the ceftazidime-susceptible rate was the highest (96.0%). 3. As for aminoglycosides, susceptibility to tobramycin and amikacin remained with a susceptible rate of 93.2% and 94.8%, respectively. 4. The carbapenem-susceptibility remained high. The susceptible rate for meropenem (94.1%) was higher than that for imipenem (88.3%). 5. Acquisition of resistance was observed in urinary isolates. Four multi-drug resistant P. aeruginosa, which are resistant to all of imipenem, amikacin and ofloxacin were isolated in this study and all were isolated from urine. 6. Of 388 isolates, 34 isolates were resistant to imipenem, but no positive isolate was found in screening of metallo-beta-lactamase-producing bacteria.
