OBJECTIVE: To investigate what type of flap used during Snodgrass or fistula repair reduces the incidence of fistula occurrence.
EVIDENCE ACQUISITION: We systematically reviewed published results for urethral covering during Snodgrass and fistula repair procedures. An initial online search detected 1740 reports. After exclusion of ineligible studies at two stages, we included all patients with clear data on the covering technique used (dartos fascia [DF] vs tunica vaginalis flap [TVF]) and the incidence of postoperative fistula.
EVIDENCE SYNTHESIS: A total of 51 reports were identified involving 4550 patients, including 33 series on DF use, 11 series on TVF use, and seven retrospective comparative studies. For distal hypospadias, double-layer DF had the lowest rate of fistula incidence when compared to single-layer DF (5/855 [0.6%] vs 156/3077 [5.1%]; p=0.004) and TVF (5/244, 2.0%), while the incidence was highest for single-layer DF among proximal hypospadias cases (9/102, 8.8%). Among repeat cases, fistula incidence was significantly lower for TVF (3/47, 6.4%) than for DF (26/140, 18.6%; p=0.020). Among patients with fistula after primary repair, the incidence of recurrence was 12.2% (11/90) after DF and 5.1% (5/97) after TVF (p=0.39). The absence of a minimum follow-up time and the lack of information regarding skin complications and rates of urethral stricture are limitations of this study.
CONCLUSION: A double DF during tubularized incised plate urethroplasty should be considered for all patients with distal hypospadias. In proximal, repeat, and fistula repair cases, TVF should be the first choice. On the basis of these findings, we propose an evidence-based algorithm for surgeons who are still in their learning phase or want to improve their results.
PATIENT SUMMARY: We systematically reviewed the impact of urethral covering in reducing fistula formation after hypospadias repair. We propose an algorithm that might help to maximize success rates for tubularized incised plate urethroplasty.
Methodology: Raloxifene (RLX) loaded liposomal-graphene nanosheet (GNS) was developed. The novelty of this work was to enhance the solubilization of RLX and improvement of its bioavailability in the disease area. So, the selection of optimized formula design of experiment was implemented which produced the desired formula with the particle size of 156.333 nm. Further, encapsulation efficiency, in vitro release, and thermodynamic stability of optimized formulation were evaluated. The optimized formulation exhibited prolonged release of RLX for a longer period of 24 h, which can minimize the dose-related toxicity of the drug. Furthermore, optimized formulation demonstrated remarkable thermodynamic stability in terms of phase separation, creaming, and cracking.
Results: The cytotoxicity study on the A549 cell line exhibited significant (P < .05) results in favor of optimized formulation than the free drug. The apoptotic activity was carried out by Annexin V staining and Caspase 3 analysis, which demonstrated remarkable promising results for optimized liposomal formulation.
Conclusion: From the findings of the study, it can be concluded that the novel optimized liposomal formulation could be pondered as a novel approach for the treatment of lung cancer.
RECENT FINDINGS: We performed a systematic search of the PubMed, EMBASE, and Web of Science databases to evaluate the impact of inguinal and pelvic LND on the oncological outcomes of PUC and to identify indications for this procedure.
RESULTS: Three studies met the inclusion criteria. The cancer detection rate in clinically nonpalpable inguinal lymph node (cN0) was 9% in men and 25% in women. In clinically palpable lymph node (cN+), the malignancy rate was 84% and 50% in men and women, respectively. Overall cancer detection rate in pelvic lymph nodes in patients with cN0 was 29%. Based on tumor stage, the detection rate was 11% in cT1-2 N0 and 37% in cT3-4 N0. Nodal disease was associated with higher recurrence and worse survival. Pelvic LND seems to improve overall survival for patients with LND regardless of the location or stage of lymph nodes. Inguinal LND improved overall survival only in patients with palpable lymph nodes. Inguinal LND had no survival benefit in patients with nonpalpable lymph nodes.
SUMMARY: The available, albeit scarce, data suggest that inguinal LND derives the highest benefit in women and in patients with palpable inguinal nodes, whereas the benefit of pelvic LND seems to be more pronounced across all stages of invasive PUC. Prospective studies are urgently needed to further address the prognostic benefit of locoregional LND in PUC.
MATERIALS AND METHODS: A Medline search was conducted according to the PRISMA statement for all English full-text articles published between 1980 and 2016 and assessing female sexual function post radical cystectomy and urinary diversion. Eligible studies were subjected to critical analysis and revision. The primary outcomes were the reporting methods for female sexual dysfunction (FSD), manifestations of FSD, and factors associated with FSD, postoperative recoverability of FSD, and awareness level regarding FSD.
RESULTS: From the resulting 117 articles, 11 studies were finally included in our systematic review, with a total of 361 women. Loss of sexual desire and orgasm disorders were the most frequently reported (49% and 39%). Dyspareunia and vaginal lubrication disorders were reported in 25% and 9.5%, respectively. The incidence of sexual dysfunction was 10% in 30 patients receiving genital- or nerve-sparing cystectomy vs. 59% receiving conventional cystectomy.
CONCLUSION: Although female sexual function is an important predictor of health-related quality of life post radical cystectomy and urinary diversion, the available literature is not enough to provide proper information for surgeons and patients.
