Comparative evaluation of prophylactic single-dose intravenous antibiotic with postoperative antibiotics in elective urologic surgery

The role of antimicrobial prophylaxis in laparoscopic nephrectomy for renal cell carcinoma

BACKGROUND

To investigate the role of antimicrobial prophylaxis in laparoscopic nephrectomy for renal cell carcinoma.

METHODS

We retrospectively enrolled 1000 patients who underwent laparoscopic nephrectomy from August 2019 to November 2021 in the Peking Union Medical College Hospital. Patients were divided into group without antimicrobial prophylaxis (n = 444) and group with antimicrobial prophylaxis (n = 556). Outcomes including 30-day postoperative infection rate, the increase rate of pre- and post-operative white blood cell counts and hospital stay were analyzed.

RESULTS

The overall infection rate was 5.0% (28/556) in the group with antimicrobial prophylaxis, which was similar to 4.1% (18/444) in the group without antimicrobial prophylaxis (P = 0.461). The increase rate of pre- and post-operative white blood cell counts was significantly lower (85.5% versus 97.0%) in the group with antimicrobial prophylaxis (P = 0.004). The postoperative hospital stay was 5 (4, 6) days in both groups (P = 0.483). Logistic regression analyses identified the use of antimicrobial prophylaxis had no influence on the occurrence of infection events (odds ratio = 0.797; 95% confidence interval, 0.435-1.460; P = 0.462). Hemoglobin (odds ratio = 0.430; 95% confidence interval, 0.257-0.719; P = 0.001) and partial nephrectomy (odds ratio = 2.292; 95% confidence interval, 1.724-3.046; P < 0.001) influenced the use of antimicrobial prophylaxis independently.

CONCLUSIONS

The use of antimicrobial prophylaxis had no impact on postoperative infection in patients receiving laparoscopic nephrectomy for renal cell carcinoma.

Compliance with Antibiotics Prophylaxis Guideline in Surgical Patients in ICUs of a Teaching Referral Hospital

Antimicrobial prophylaxis used for surgical procedures remains one of the measures for the prevention of surgical site infections (SSIs). The present study was designed to assess the compliance with clinical practice guideline for antimicrobial prophylaxis in variable surgeries conducted in the intensive care units (ICUs) of a major referral hospital. This cross-sectional investigation was carried out by prospective data collected from October 2017 to March 2018 in the intensive care unit (ICU) of Nemazi hospital in Shiraz. Demographic characteristics, surgery type as well as antibiotic treatment were gathered from medical records and entered in data collection forms. We reviewed compliance and adherence of prophylactic antibiotic administration to the Infectious Diseases Society of America (IDSA) guideline and evaluated the courses of antimicrobial drugs. If an antibiotic administrated for surgical prophylaxis was different from the guideline, the antibiotic was classified as non-guideline-based antibiotics. Most patients participated in this study were male (64.5%). Only 8.75% of the administrated antibiotics chosen for surgical prophylaxis were found to be appropriate antibiotic prescriptions; however, those patients receiving appropriate antibiotics prescribed an inappropriate dosage. In addition, the antibiotics were administrated with inappropriate durations in all cases. Our findings indicated that adherence to the IDSA international guideline seems to be far from ideal in Namazi hospital for antimicrobial prophylaxis, resulting in the unsuitable administration of a wide variety of antibiotics.

Obstructive uropathy due to prolapsed lower ureters and bladder in patients with severe procidentia: A report of two cases

INTRODUCTION

Pelvic organ prolape is not uncommon in multi-parous or elderly women. It is one of the rare but important causes of obstructive uropathy. Herein, we report two cases of severe procidentia that were referred with obstructive uropathy due to prolapsed bladder and ureters.

PRESENTATION OF CASE

The first case was a 78-year-old woman, with severe pelvic organ prolape and secondary bilateral hydroureteronephrosis and post-renal failure. She was treated successfully by bilateral nephrostomy insertion and then pessary insertion. The second case was a 75-year-old woman who referred with the same presentation, but treated surgically with burch colposuspention and synchronous bilateral ureteral stent insertion.

DISCUSSION

Pelvic organ prolapse is not uncommon in old women. In addition to physical problems of procidentia, it may cause acute renal failure (ARF), chronic renal failure (CRF), and finally end stage renal disease (ESRD) if undiagnosed.

CONCLUSION

In every aged female case with obstructive uropathy and/or bilateral hydroureteronephrosis with unknown causes, gynecologic examination should be performed for early detection of possible pelvic organ prolapse. Appropriate management is necessary to prevent renal failure from uterine prolapse (UP).

The feasibility of regional anesthesia in the percutaneous nephrolithotomy with supracostal approach and its comparison with general anesthesia

There are various approaches for the percutaneous nephrolithotomy (PCNL). Supracostal approach is a well known technique for doing of it. This approach is being done commonly under general anesthesia (GA). In this retrospective study, we evaluated the feasibility of supracostal PCNL under regional anesthesia (RA) and compared it with the same procedure under GA. Since March 2000 to March 2005, a total of 123 renal stone cases underwent PCNL with supracostal access in our center. GA was selected in 69 cases (56 %) (Group 1), spinal anesthesia (SA) in 45 cases (36.5 %), and epidural anesthesia (EA) in 9 cases (7.5 %) (Group 2). The operative time, success rate, hospital stay, and ensuing complications were compared between group 1 and group 2. There were no significant differences between groups 1 and 2 among surgical parameters, including age, stone area, anesthesia time, and hospitalization time (P > 0.05). There was no difference in the rate of complications or success rate between GA and RA cases (P > 0.05). Overall complete stone free rate, regardless of stone size, in relation to type of anesthesia was as follows: 88.4 % for GA, 88.9 % for EA, and 91.1 % for SA (P > 0.05). Conversion to GA was not needed in any patient with RA. The results showed that the supracostal PCNL with regional anesthesia was feasible but without evident advantages versus general anesthesia in this population, and possible advantages of the procedure in patients with pulmonary co-morbidities have still to be evaluated. The anesthesia related complications of RA were negligible and easily controllable.

Transperitoneal laparoscopic heminephrectomy in duplex kidneys: a one centre experience

PURPOSE

The standard treatment for a duplex kidney with poorly functioning upper pole moiety is ipsilateral upper pole heminephrectomy. This procedure is usually performed by open surgery, but with recent developments in techniques of uro-laparoscopy, it can be done with it, safely. In this study we evaluated the results and safety of laparoscopic heminephrectomy in our consecutive cases.

MATERIALS AND METHODS

From February 2001 to May 2007 fourteen unilateral laparoscopic heminephrectomy were performed in our center. Patients' characteristics, presenting symptoms, operative time, and blood loss, early and late complications were all collected retrospectively. Using pre-operative ultrasonography, intravenous pyelography (IVP) and CT scanning, unilateral upper pole hydronephrosis was detected in all cases. By DMSA isotope scan hypofunctioning of ipsilateral moieties was detected in all cases.

RESULTS

Mean operative time was 203±80 minutes. No major intra-operative or early complications were identified. Mean hospital stay was 4.1 days. On mean follow-up of 32 months no disturbing symptoms or episodes of urinary tract infections (UTIs) were detected. Atrophic kidney was detected in one case in post-operative IVP.

CONCLUSION

Laparoscopic heminephrectomy is a valuable minimal invasive procedure that can be performed safely in experienced hands without any important complication. Perfect renal pedicles vascular system manipulation is important for the preservation of renal function post-operatively.
