Condylomata acuminata of external urethral meatus causing infravesical obstruction

The Annual costs of treating genital warts in the Public Healthcare Sector in Peru

OBJECTIVES

To estimate the cost of six different techniques used to treat Genital Warts and the annual average cost of treating a typical GW patient in Peru. To estimate the annual economic burden diagnosing and treating GW in the Peruvian public healthcare system.

METHODS

We developed a prevalence-based, cost-of-illness study from the provider's perspective, the healthcare facilities under the purview of Peruvian Ministry of Health. We used an activity-based costing approach. We conducted primary data collection in three regions in Peru and supplemented it with governmental data. Uncertainty of the costing estimates was assessed via Monte Carlo simulations. We estimated the average cost and associated confidence intervals for six treatment options - three topical and three surgical - and the overall cost per patient.

RESULTS

The average treatment cost per patient was 59.9USD (95 %CI 45.5, 77.6). Given a population of 18.4 million adults between 18 and 60 years of age and a GW prevalence of 2.28 %, the annual cost of treating GW was 25.1 million USD (uncertainty interval 16.9, 36.6).

CONCLUSIONS

This study provides the first quantification of the economic burden of treating genital warts in Peru and one of the few in Latin America. The costing data did not include other healthcare providers or out-of-pocket expenditures, and hence we present a conservative estimate of the COI of GW in Peru. Our findings bring attention to the financial burden of treating GW, a vaccine-preventable disease.

Update on the Medical and Surgical Management of Urethral Condyloma

INTRODUCTION

Condyloma acuminata (CA) of the urethra presents a management challenge due to high recurrence rates, difficulty in accessing urethral lesions, risk of stricture formation, and potential for sexual dysfunction. While standard treatment modalities are acceptable for some external genital condyloma, they are not always feasible or appropriate for urethral lesions.

OBJECTIVES

We sought to review the literature on epidemiology, presentation, diagnosis and treatment of urothelial CA with a focus on surgical treatment options.

METHODS

We performed a comprehensive literature search of PubMed to identify all studies pertaining to urethral CA through November 2020.

RESULTS

Urethral CA is a relatively rare, but challenging disease to manage with a considerable amount of treatment side effects and downstream morbidity associated. In our comprehensive review we have found a wide selection of treatment modalities ranging from minimally invasive strategies to surgical reconstructive techniques. Proper follow-up to monitor for disease recurrence at the 3-4 month mark is appropriate and will determine subsequent treatment strategies as needed. Future studies and treatment directions include novel drug delivery models to optimize minimally invasive topical drug efficacy.

CONCLUSION

Treatment of urethral CA should be approached in a step-wise fashion. Medical therapy would be an appropriate option for asymptomatic or minimally symptomatic patients with small lesions who desire to avoid any interventions. If patient is symptomatic, has extensive disease burden or has failed medical therapy intervention should be considered with options including PDT, laser ablation or surgical excision with or without urethral reconstruction. Appropriate selection depends on patient characteristics and preferences along with prior treatment history. Kim CJ, Campbell SP, Allkanjari A, et al.

The effects of vitamin B12, vitamin D, ferritin level, neutrophil/monocyte ratio and some blood parameters on genital warts presence, the number of lesions, and recurrence rates

The relationships between cancer caused by HPV and some vitamins, as well as leucocytes and their ratios, have been investigated in the literature. Our aim is to evaluate these relationships at the level of genital wart in terms of the investigated parameters and lesion numbers. Data were obtained from 98 and 94 patients for groups one and two, including warts patients and healthy people respectively. The Neutrophil/Monocyte ratio and lesion numbers in the warts patients were reported and analysed in terms of vitamin B12 and D, ferritin and leucocytes. A correlation was established between lesion numbers, age and midcorpuscular volume (p <0.05). There was no correlation between lesion numbers and recurrence. According to the comparative analysis, there were differences in terms of ferritin, neutrophil, monocyte, haemoglobin, midcorpuscular volume and neutrophil/monocyte ratio between groups. The cut-off values for neutrophil, monocyte and N/M ratios were 56.45, 4.91 and 7.825 respectively. While our study showed that wart development may be affected by blood ferritin levels and in this situation, midcorpuscular volume, neutrophil, monocyte and N/M ratios may change, a relation was found between lesion numbers and age and mean midcorpsucular volume values only. However, further studies are needed to clarify this issue.

HPV infection in urology practice

Human papillomavirus (HPV) is the most common pathogen of sexually transmitted disease worldwide. While HPV is responsible for low-grade benign lesions in the anogenital area such as condyloma acuminatum, it is also strongly associated with cervical, anal, vulvar/vaginal, and penile carcinomas. In addition to being an oncogenic virus, HPV causes a substantial socioeconomic burden due to the recurrence of benign lesions, the lack of a definitive treatment option that provides a complete cure, and the high cost of treatment. The global incidence of HPV infection is rising, especially among young and sexually active individuals; as a result, in recent years these infections have also become increasingly conspicuous in urology practice, both as incidental findings and primary complaints. The aim of this review is to evaluate the pathogenesis, diagnosis, and treatment modalities of HPV infections in light of the current literature from the urologist's perspective.

Treatment of intraurethral condylomata acuminata with surgery and cidofovir instillations in two immunocompromised patients and review of the literature

Condylomata acuminata (CA) or anogenital warts are benign proliferative lesions caused by low-risk human papillomaviruses (HPV). Treating CA can be very frustrating for patients and clinicians due to the high recurrence rates. Immunosuppression is associated with larger size of CA that are more frequently resistant to treatment. Surgical approaches tend to be poorly effective in the long-term because of high recurrence rates related to the persistence of HPV-infected cells. In our search to find an agent to treat intraurethral CA with minor or no side effects, we evaluated intraurethral cidofovir in two male patients, who were under immunosuppressing therapy due to organ transplantation and suffered from extensive urethral HPV lesions. Both patients underwent biopsy of the lesions and initial transurethral resection. In our first case, intraurethral cidofovir instillations were started after 2 months due to recurrence after surgical treatment. In our second case, intraurethral cidofovir was administered after surgery because of incomplete resection of extensive lesions. Because of persistent or rapidly recurrent lesions despite intraurethral cidofovir instillations, the first patient needed two additional surgical interventions while the second patient underwent one additional surgical intervention. After surgical intervention, both patients received again adjuvant cidofovir instillations without side effects. Over a period of 56 weeks, both patients received each a total of 28 instillations with cidofovir. Following 3.5 years (patient 1) of the last cidofovir instillation, no recurrences were observed in our first patient. Following 6 months of the last cidofovir instillation (patient 2), two very small recurrent lesions in the most distal part of the urethra were observed in our second patient for which he will receive a cycle of 6 cidofovir instillations in the near future. Intraurethral cidofovir is a safe, easy-to-use, well-tolerated and an effective adjuvant to surgery for extensive intraurethral CA in immunocompromised patients.

Comparison of the risk factors and HPV types in males with anogenital warts with and without involvement of the urethral meatus in western Iran

BACKGROUND

Human papillomavirus (HPV)-induced lesions rarely develop in the urethral meatus (UM); however, their eradication can be problematic.

METHODS

A total of 22 patients with anogenital warts (AGWs) in the UM region and 22 patients with AGWs located at other anatomical sites were included in this cross-sectional study. The presence of human papillomavirus (HPV) types in biopsy samples was determined using the HPV Easy typing kit (GenID GmbH, Germany).

RESULTS

Although the patients in the AGW group with involvement of the UM had a higher incidence of reported multiple sexual partners (63.6% vs. 40.9%), larger meatus size (81.8% vs. 36.4%), and more frequent anal (36.4% vs. 18.2%) or unprotected sexual contact (68.2% vs. 36.4%) than those in the AGW group without UM involvement, only the duration of lesions (p = 0.04) and meatus size (p = 0.004) were significantly different in both groups. Low-risk HPV types were found in 75.0% and 69.2% of patients in the AGW groups with and without UM involvement, respectively.

CONCLUSION

We found that a larger UM size was more prone to the development of meatus AGWs; however, being married, delaying sexual debut, and avoidance of multiple sexual partners seemed to be associated with a decreased risk of development of AGWs, especially within the UM region.

Periurethral and vulval condylomata acuminata: an unusual juvenile venereal disease in a 3-year-old girl

We present a case of giant condyloma acuminatum (CA) in a 3-year-old girl with rapidly growing vulval and periurethral lesions, which was investigated thoroughly and successfully treated with excision biopsy. Genital warts in the form of giant alarming vestibular, vulval and periurethral lesions of CA are very rare in children. There is need for a multidisciplinary approach with potential sociomedicolegal implications. Surgical excision is safe, effective and provides an opportunity to assess the extent of the lesion and tissue for accurate diagnosis. Genital warts in the form of giant alarming vestibular, vulval and periurethral lesions of CA are very rare in children. Indications for surgical treatment include large, recurrent or refractory lesions, as well as the need for histological identification and acquiring tissue for immunotherapy when necessary. The strategy of an extended follow-up is recommended so as to ensure identification of any risk situations.

Female urethral condyloma causing bladder outlet obstruction

In women, urethral condyloma rarely leads to a bladder outlet obstruction. A 39-year-old woman who presented with frequency, urgency, and residual urine sensation was found to have a condyloma in her urethral meatus. Urodynamic study indicated bladder outlet obstruction. After condyloma excision, she returned to normal voiding, and the free maximum flow rate improved. In women, excision of urethral condylomas that cause obstruction can be an effective treatment with early recovery of voiding function.
