The majority of paediatric surgeons will encounter a patient with prune belly syndrome (PBS) only a few times in their clinical practice. There have been many opposing views in the literature regarding the pathogenesis and management of this complex condition. A detailed review was conducted using PubMed to identify key publications involving PBS. This article discusses the evolution of our understanding of the pathogenesis and diagnosis of PBS, including its typical characteristics. We describe the management options available for bilateral intra-abdominal testes, the deficient abdominal wall, the dilated urinary system and examine the evidence base used to support the current approaches employed.

International guidelines recommend using local susceptibility data to direct empiric therapy for acute uncomplicated cystitis. We evaluated outpatient urinary isolate susceptibility trends in New York State. Nitrofurantoin had the lowest resistance prevalence whereas trimethoprim-sulfamethoxazole and fluoroquinolones had higher prevalences. This study highlights the need for local outpatient antimicrobial stewardship programs.

BackgroundOutpatient prescribing for acute uncomplicated cystitis is a significant driver of antimicrobial use. Empiric therapy should be based on local susceptibility data. However, there is limited guidance on regional susceptibility trends in outpatient settings. This study describes the epidemiology and prevalence of antimicrobial resistance in uropathogens in New York State outpatient settings to help inform empiric treatment decisions.MethodsRetrospective analysis of positive urine cultures sent to Quest Diagnostics in 2016 from outpatient settings. Cultures that grew ≥105 CFU/mL were included from 17 NYS counties. Bacterial identification and antimicrobial sensitivities were determined on the Vitek-2 using CLSI M-100 S-25 breakpoints. Data were summarized as proportions and stratified by age (<17, 18–64, ≥65) and sex.ResultsOver 78,000 isolates were included (Table 1). The most prevalent isolates were Escherichia coli (65.2%), Enterococcus spp. (11.9%), and Klebsiella pneumoniae (9.9%). E. coli was highly susceptible to nitrofurantoin (NTF, 97.2%) and cefazolin (CFZ, 89.9%) and less susceptible to trimethoprim–sulfamethoxazole (TMP-SMX, 72.9%) and ciprofloxacin (CIP, 78.0%). Enterococcus spp. was highly susceptible to NTF (99.0%) and ampicillin (99.8%). K. pneumoniae was highly susceptible to TMP-SMX (90.0%) and CIP (95.2%) and markedly less susceptible to NTF (42.0%). E. coli was more prevalent in females (69.7% vs. 39.6%, P < 0.001). Enterococcus was more prevalent in males (39.6% vs. 10.1%, P < 0.001). The prevalence of K. pneumoniae was similar in men and women (9.6% vs. 10.1%, P = 0.08). Resistance was more prevalent in males (NTF: 6.3% vs. 4.2%; TMP-SMX: 26.3% vs. 22.7%; CIP: 35% vs. 17.3%) and for adults ≥65 (NTF: 6.2% vs. 3.6%; TMP-SMX: 25.1% vs. 22.1%; CIP: 30.0% vs. 14.0%) P < 0.001 for all comparisons.ConclusionNTF appears to be the best empiric choice for outpatient treatment of acute uncomplicated cystitis in New York State. TMP-SMX and ciprofloxacin should be avoided empirically. These data also highlight the necessity to obtain uropathogen sensitivity data to confirm empiric therapy or make appropriate adjustments in the outpatient setting.Table 1.
