Bacterial species cultured after electrofulguration in women with a history of antibiotic-recalcitrant urinary tract infections frequently compare with pre-fulguration findings: a pilot study.

Electrofulguration (EF) of areas of chronic cystitis in women with antibiotic-recalcitrant recurrent urinary tract infections (RUTIs) can result in improvement of their urinary tract infections (UTIs). We compared urine culture (UC) findings in patients before and after EF, as well as how they vary with cystitis stage at the time of EF, to evaluate for persistent species. After obtaining institutional review board approval, we retrospectively reviewed a prospectively maintained database of EF patients for those with positive UC findings in the 3-6 months preceding EF. Patient pre-EF UC was then compared with first positive UC after EF prompted by a new symptomatic UTI episode, with the hypothesis that the same species will be identified before and after EF. Exclusion criteria included UC from outside institution, neurogenic bladder, and need for catheterization. Ninety-nine women with pre- or post-EF UC-recorded organisms met the study criteria. The median age was 65 years (interquartile range 64-74), with a median time to first positive culture following fulguration of 9.7 months. For 26 patients with positive cultures both pre- and post-EF, the same organism was present in both cultures in 73% of the patients, with predominantly Escherichia coli. EF was effective at reducing the rate of UTIs in this population. For women undergoing EF for antibiotic-recalcitrant RUTIs and associated chronic cystitis lesions, 73% of those with a UC obtained at the time of a first symptomatic recurrent UTI episode post-EF expressed the same organism as before EF. Further study is needed to better understand the evolution of the microbiome post-EF.IMPORTANCEAmong women who experience a recurrent urinary tract infection after a fulguration procedure on areas of chronic cystitis in their bladder, there are no data available on whether the bacterial species found in urine cultures are the same or different from those present before fulguration. By removing the inflamed surface layer of cystitis during fulguration, it is possible that the procedure unmasks deep-seated bacteria. The bacterial kingdom in the bladder wall of these chronically infected women may be different from what is expressed sporadically in urine cultures. Confirming prior studies, we found that fulguration in women with antibiotic-recalcitrant recurrent urinary tract infections and cystitis lesions was effective at reducing the rate of urinary tract infections. At the time of a first symptomatic recurrent UTI episode post-fulguration, 73% expressed the same organism in urine culture as before fulguration. Further study is needed to better understand the evolution of the microbiome post-EF. This article evaluates persistent infections after electrofulguration of areas with chronic cystitis in post-menopausal women with antibiotic-recalcitrant recurrent urinary tract infections. Pre-fulguration urine cultures were compared with the first positive urine culture prompted by a new symptomatic UTI episode after electrofulguration, with the hypothesis that the same species will be identified before and after the fulguration procedure. Electrofulguration was effective at reducing the rate of UTIs in this population. However, 73% of those with a urine culture obtained at the time of a first symptomatic recurrent UTI episode post-electrofulguration expressed the same organism (predominantly Escherichia coli) as before the fulguration procedure. Further study is needed to better understand the evolution of the microbiome after electrofulguration.

Long-term efficacy of complete trigonal electrofulguration for women with recurrent urinary tract infections.

INTRODUCTION AND OBJECTIVE: Recurrent urinary tract infections (R-UTIs) have a negative impact on quality of life and contribute to antimicrobial resistance. Long-term antibiotic therapy is the main treatment alternative but, in some cases, this approach may not be accepted by the patient, is ineffective or poorly tolerated. In selected women, electrofulguration (EF) of trigonal lesions has been shown to reduce urinary tract infection (UTI) episodes. METHODS: Between August 2006 and December 2017, 73 women with R-UTI had their data collected prospectively and analyzed. We evaluated the rate of UTIs during the initial 2 years of follow-up after fulguration based on symptoms and a positive urine culture. All patients failed with multiple antibiotic courses and were offered endoscopic electrofulguration of the entire trigonal and bladder neck mucosa with a rollerball probe. We present our long-term results using a strategy of complete fulguration of the trigone in women with R-UTIs. RESULTS: The median age was 64 years (range: 17-76 years) and the median follow-up time after EF was 4.2 years (range: 2.5-14 years). Overall, 70 patients (96%) remained free of UTI episodes during the first year of follow-up, at 2 years of follow-up, 57, 53% remained infection-free. Currently, UTIs are typically sparse, mild, and caused by multisensitive bacteria. CONCLUSIONS: Complete trigonal and bladder neck mucosal fulguration promoted a significant reduction of UTI episodes during the first 2 years of follow-up. Prospective controlled studies are needed to determine the role of EF in women with R-UTI.

Electro-fulguration for extensive inflammatory bladder lesions in post-menopausal women with antibiotic-recalcitrant recurrent urinary tract infections.

INTRODUCTION AND HYPOTHESIS: To evaluate how women with uncomplicated antibiotic-recalcitrant recurrent urinary tract infections (RUTIs) and extensive inflammatory bladder lesions on office cystoscopy responded to electro-fulguration (EF) to eliminate these chronic bladder sites. METHODS: After IRB approval, a retrospective study of non-neurogenic women with RUTIs, inflammatory lesions on cystoscopy, and who underwent EF was performed. Lesions were classified through a simplified staging system based on the extent of bladder wall involvement. Only those with extensive bladder wall involvement (stages 3 and 4) at the time of EF were analyzed in this report. Six months after EF, an office cystoscopy was performed, with endoscopic success defined as no lesions seen. The primary clinical outcome was number of symptomatic UTIs after EF, defined as cure (0/year), improvement (1-2/year), and failure (≥3/year). RESULTS: From 2007 to 2019, a total of 57 women met the study criteria, 30 stage 3 and 27 stage 4. Nineteen (63%) were endoscopically successful in stage 3 and 11 (41%) in stage 4. Mean follow-up was 2.9 years (stage 3) and 3.1 years (stage 4). All had at least a 6-month UTI follow-up after the 6 months of office cystoscopy, with 15 patients cured, 37 improved, and 5 failed (all stage 4). CONCLUSIONS: Although EF only resulted in 63% complete endoscopic resolution, the majority experienced a decrease in the frequency of UTIs, suggesting that EF can be durably effective even in women with very extensive cystitis lesions.

Reduced urothelial expression of uroplakin-IIIa in cystitis areas in bladders of postmenopausal women with recurrent urinary tract infections: pilot study.

PURPOSE: To study human bladder biopsies to investigate urothelial response to UTI, expression of uroplakin, and urothelial response after healing from cystoscopy with electrofulguration (CEF) treatment for antibiotic-recalcitrant RUTI. METHODS: Following IRB approval, cold cup bladder biopsies from "no cystitis" and "cystitis" regions were obtained from women with antibiotic-recalcitrant rUTI undergoing CEF under anesthesia. "No cystitis" and "cystitis" biopsies from 14 patients (5 had prior CEF, 9 naïve) were analyzed by immunofluorescence (IF) confocal microscopy using antibodies against uroplakin-IIIa. For an additional 6 patients (2 prior CEF, 4 naïve), only "cystitis" area biopsies were taken and analyzed. Cytokeratin 5 (marker for squamous metaplasia) staining was performed on 14 patients. RESULTS: In healthy tissue, uroplakin-IIIa staining was observed as a contiguous line on the luminal surface of umbrella cells. In "cystitis" areas for 19/20 patients, there was either no uroplakin-IIIa staining observed or spotty (+) staining. The "cystitis" regions of all patients had less intense uroplakin-IIIa staining compared to the matched "no cystitis" area in the same patient. In patients post-CEF but requiring repeat EF for persistent RUTI lesions, healed areas served as control and in 3 of 7 patients no uroplakin-IIIa staining was observed. Squamous metaplasia was observed in 10 patients. CONCLUSION: In bladders of postmenopausal women with antibiotic-recalcitrant RUTI, areas with visible cystitis expressed less uroplakin-IIIa, supporting the model of urothelial exfoliation in response to UTI.

Electrofulguration-assisted dermabrasion is comparable to manual dermabrasion in patients undergoing autologous non-cultured epidermal cell suspension for treatment of stable vitiligo: A randomized controlled trial.

BACKGROUND: Recipient site preparation is a crucial step in non-cultured epidermal cell suspension (NCES) as it facilitates proper uptake of the grafted melanocytes. OBJECTIVES: To compare the repigmentation rate of recipient sites prepared with manual dermabrasion (MD) versus electrofulguration-assisted dermabrasion (EF) in patients undergoing NCES for treatment of stable vitiligo. METHODS: This was a prospective randomized study including 26 patients of stable vitiligo (VIDA 0 or -1), each having two patches of size greater than 3 × 3 cm located symmetrically or at the same site or a single patch of 6 × 6 cm or larger. After randomization of patches in the given patient, MD and EF were performed on recipient areas followed by NCES. The patients were followed up at 4 weekly intervals up to 24 weeks and assessed for extent of repigmentation and adverse effects if any. RESULTS: Greater than 75% repigmentation was observed in 69.3% of the patches prepared by MD as compared to 73.1% patches prepared by EF at the end of 24 weeks (p = 0.791). The mean improvement in target VASI was 64.0% in the MD group as compared to 68.8% in the EF group (p = 0.21). Patches prepared by EF achieved successful repigmentation earlier as compared to patches prepared by MD (9.4 weeks vs 11.4 weeks, p = 0.12). CONCLUSION: Both MD and EF have comparable outcomes with respect to all parameters.

Multiple Koenen Tumors, a Rare Entity: Combination Treatment with 1% Topical Sirolimus Electrofulguration and Excision.

INTRODUCTION: Koenen tumors are benign, cutaneous manifestations of tuberous sclerosis. These are disfiguring, painful, and challenging to treat as they frequently recur. We report a case of long-standing, multiple Koenen tumors affecting all twenty nails in an elderly female who was successfully treated with a combination of topical sirolimus 1%, surgical excision, and electrofulguration. CASE REPORT: A 57-year-old lady presented with multiple, asymptomatic periungual, and subungual tumors affecting all twenty nails since 27 years. Cutaneous examination revealed confetti macules, ash-leaf macule, and shagreen patch over trunk. Nail biopsy was compatible with Koenen's tumor. Computerized tomography of brain showed diffuse patchy sclerosis. The tumors were treated with topical sirolimus 1% ointment for 10 months with excellent regression. Electro-fulguration for both great toenails and surgical excision of right thumbnail periungual fibroma was done. 1% sirolimus was advised after the surgical treatment. There were no adverse effects or recurrence of tumors over a 2-year follow-up. DISCUSSION: Topical sirolimus 1% was effective in tumor regression and preventing new tumor formation. Larger tumors that interfered in daily chores were treated with excision and electrofulguration. Thus, a combination treatment for this rare presentation of tuberous sclerosis provided optimum results.

Vesicular Cystitis: A Chronic Cystitis Variant Often Unresponsive to Antibiotics and Electrofulguration.

OBJECTIVE: The aim of the study was to report on the presentation and outcomes of vesicular cystitis (VC), a chronic cystitis exhibiting translucent bladder mucosal vesicles, among women with antibiotic-refractory recurrent urinary tract infections (RUTIs). METHODS: An analysis of our Institutional Review Board-approved series on antibiotic-refractory RUTIs was performed, selecting for documented VC lesions on cystoscopy. All patients had RUTIs defined as ≥3 urinary tract infections/year with positive urine culture. All patients were extensively treated with antibiotics with no resolution of RUTIs and were offered electrofulguration (EF) of VC lesions under anesthesia as a last resort. All patients had a 6-month post-EF office cystoscopy documenting persistence or resolution of the lesions, and a clinical outcome assessment based on RUTI frequency. RESULTS: Of 482 patients, 18 (3.7%) treated during 2011-2017 met the study criteria. VC was most commonly found over the dome/anterior wall (7/18, 38%) and as pancystitis (7/18, 38%). There was often concomitant cystitis cystica of the trigone (8/18, 44%). At post-EF cystoscopy, persistence of VC was noted in 10/18 (56%) patients; 6/18 (33%) underwent repeat EF and an additional 3/18 (17%) were retreated due to new lesions after initial resolution. Two (11%) patients required simple cystectomy and urinary diversion due to RUTIs refractory to all interventions. Within a median follow-up of 2.8 years after EF, clinical cure was observed in 5/18 (28%), improvement in 10/18 (56%), and failure in 3/18 (17%) patients. CONCLUSIONS: Among women with antibiotic-refractory RUTIs, VC is an infrequent and persistent form of cystitis with a predilection for non-trigonal bladder surfaces, whose management is challenging.

Electrofulguration in the advanced management of antibiotic-refractory recurrent urinary tract infections in women.

OBJECTIVE: To evaluate the long-term efficacy of electrofulguration in women with recurrent urinary tract infections. METHODS: After institutional review board approval, a retrospective study of women who underwent electrofulguration alone was carried out. All patients had recurrent urinary tract infections defined as three or more urinary tract infections/year, and a preoperative office cystoscopy showing inflammatory lesions, categorized by location: urethra, bladder neck, trigone and beyond the trigone. All lesions were cauterized during outpatient electrofulguration under anesthesia. On 6-month postoperative office cystoscopy, endoscopic success was defined as resolution of all lesions previously seen and no new lesions. The primary outcome was urinary tract infections/year, with urinary tract infection defined as antibiotic treatment for urinary tract infection-like symptoms and/or for positive urine culture. Clinical cure was defined as no further urinary tract infections, clinical improvement as less than three urinary tract infections/year, and clinical failure as three or more urinary tract infections/year. RESULTS: Of 95 women who met the study criteria between 2004 and 2016, 62 (65%) were endoscopically successful, and 33 (35%) were endoscopic failures based on postoperative cystoscopy. Among all patients, over a median follow-up period of 4.9 years, the median number of urinary tract infections/year was 0.8. Endoscopically successful patients had fewer urinary tract infections/year compared with endoscopic failures (0.6 vs 0.9, P = 0.03). Clinically, 14 (15%) patients were cured, 69 (73%) were improved and 12 (13%) failed. Compared with clinically improved patients, clinical failures were more likely to have infections with multiple organisms (92% vs 35%, P < 0.001) and highly resistant organisms (92% vs 23%, P < 0.001). CONCLUSIONS: In our experience, nearly two-thirds of women with recurrent urinary tract infection can be successfully treated with electrofulguration, and >80% experience long-term clinical cure or improvement in urinary tract infections.

Late diagnosis of posterior urethral valves.

CLINICAL PROBLEM: We diagnosed 8 patients with late-stage posterior urethral valves (PUV) between 1 and 14 years of age. Five patients complained of symptoms related to voiding dysfunction. The other 3 patients required urethrocystoscopy for other reasons (hypospadias fistulae, difficulty with catheterisation and high-grade vesicoureteral reflux [VUR]). A second review of the first 2 patients' medical history showed voiding dysfunction symptoms. All patients underwent preoperative ultrasonography: 3 patients had normal results and 5 had renal or vesical disorders. The diagnosis was reached through voiding cystourethrogram (VCUG), and 4 patients underwent urodynamic studies. The diagnosis was confirmed by urethrocystoscopy, performing valve electrofulguration. We performed urethrocystoscopy during the check-ups at 3-6 weeks and observed no stenosis. The symptoms disappeared for all patients after 20 months of follow-up. The patient with VUR was cured. The ultrasounds showed no progression of the renal involvement and showed improvement in the vesical involvement. The velocimetries during check-ups presented curves within normal ranges. DISCUSSION: Most children with PUV are diagnosed through ultrasound during the neonatal period. Some patients present PUV at later ages with diverse symptoms, which impedes its diagnosis. We should suspect PUV in male patients with symptoms of voiding dysfunction, either when they have normal or pathological results from ultrasounds or VCUG. We recommend performing urethrocystoscopy to rule out urethral obstruction.

Electrosurgery: part I. Basics and principles.

The term electrosurgery (also called radiofrequency surgery) refers to the passage of high-frequency alternating electrical current through the tissue in order to achieve a specific surgical effect. Although the mechanism behind electrosurgery is not completely understood, heat production and thermal tissue damage is responsible for at least the majority--if not all--of the tissue effects in electrosurgery. Adjacent to the active electrode, tissue resistance to the passage of current converts electrical energy to heat. The only variable that determines the final tissue effects of a current is the depth and the rate at which heat is produced. Electrocoagulation occurs when tissue is heated below the boiling point and undergoes thermal denaturation. An additional slow increase in temperature leads to vaporization of the water content in the coagulated tissue and tissue drying, a process called desiccation. A sudden increase in tissue temperature above the boiling point causes rapid explosive vaporization of the water content in the tissue adjacent to the electrode, which leads to tissue fragmentation and cutting.

Surgical Approach for Polycystic Ovarian Syndrome in Management of Infertility.

BACKGROUND: In patients with Polycystic Ovarian Syndrome (PCOS), resolution of infertility is an important goal of treatment. Wedge resection of the ovaries described as a means to achieve this was practiced in the middle of twentieth century. With the advent of endoscopic surgery, surgical approach for the same condition has been modified. Multi point biopsy, multiple needle puncture, electofulguration and laser fulguration are being tried in the context of PCOS. This project was taken up to evaluate the scope of electo fulguration in clomiphene resistant PCOS. METHODS: Forty patients who did not show sonographic evidence of ovulation with clomiphene citrate (CC) 100mg OD for 05 days in two cycles were subjected to laparoscopy. The patients who did not show any pelvic factor for infertility were alternately assigned to electro - fulguration treatment of ovaries or no fulguration during laparoscopy. These were designated as 'Lap EC' & 'Only CC' group respectively. For 'Only CC' group' stimulation with CC was continued for four cycles with a higher dose 150 mg OD for 05 days. Lap EC group were subjected to CC 100mg OD for 5 days for two cycles in case of non achievement of ovulation in the first two drug free cycles following EC. Folliculometry, HCG administration and Intra Uterine Insemination (IUI) was performed for both groups. RESULTS: Total percentage of ovulatory cycles were 51.8% in EC group compared to 5.26% in the CC group. Overall pregnancy rate of 30% was achieved in the Lap EC group as compared to only 10% in the CC group (p<0.05). CONCLUSION: Laparoscopic electrofulguration of ovaries increases the chances of ovulation and conception. This being a cheaper one time procedure as compared to other expensive ovulation inducing agents, should be the preferred mode and the primary procedure wherever polycystic ovaries are encountered while evaluating a case of infertility by laparoscopy.

Clinical Evaluation of the Transurethral Electrofulguration on Female Urethritis / 대한비뇨기과학회지

During the period from October 1, 1973 to September 31, 1976, 227 cases of female urethritis, confirmed by endoscopy, classified four groups by endoscopic findings and studied clinically according to groups respectively. And also the effects of the transurethral electrofulguration on the female urethritis (Groups III and IV) were evaluated. The following results were obtained. 1) The endoscopic classifications were as follows. Group I: Almost normal urethra and bladder neck or with very mild mucosal changes, 13 cases. Group II: Mild granular hyperemia of the urethral mucosa with almost normal bladder neck, 55 cases. Group III: Marked bullous and granular hyperemia of the urethral mucosa and mild bullous bladder neck with a few pseudopolyps, 86 cases. Group IV: Marked bullous and granular hyperemia of the urethra and marked bullous bladder neck with many pseudopolyps, 73 cases. 2) Of 227 cases, 79 (34.8%) were observed most frequently in the groups of 31~40 years of age. 3) Common urinary symptoms were frequency 69.2%, tenesmus 61.7%, urgency 26%, dysuria 14.5%, painful urination 14.5%, small urinary stream 11.0%, hesitancy 10.5%, terminal hematuria 9.7%. Terminal hematuria was more commonly observed in Groups III and IV rather than Groups I and II. Non-urinary symptoms were suprapubic discomfort 33.5%, lumbago 20.3%, headache 9.3%, general weakness 7.5%. 4) Of 227 cases, 147 (64.8%) were normal urinalysis (Albumin (-), Sugar (-), below 5 WBC/HPF AND 3 RBC/HPF) and 187 (82.4%) were bacteriologically negative on Gram's stain. 5) On cystoscopy, the most frequently observable bladder change was trabeculation (More than 60% in all Gruops) In almost all cases of the bladder trabeculation, there were always mederate or remarkable changes in the urethral and in the bladder neck. 6) 23 out of 159 cases in Group III and IV, were treated with transurethral electrofulgulation, urethral instillation, urethral dilation, if necessary. Of 23 cases, 22 (more than 95%) were completely cured or improved. But in Groups III and IV cases, treated with only conservative method, failure rates of the treatment were 25.7%, 22.2% respectively.
