Purpose: To compare the polypropylene mesh (Marlex®) to Vicryl®, Parietex composite® and Ultrapro® meshes to assess the occurrence of adhesions in the intraperitoneal implantation. Methods: Sixty Wistar rats were allocated into three groups: PP+V, in which all the animals received a polypropylene and a Vicryl® mesh; PP+PC, with the implantation of polypropylene and Parietex composite® meshes and PP+UP, in which there was implantation of polypropylene and Ultrapro®. Macroscopic analysis was performed 28 days later to assess the percentage of mesh area affected by adhesion. Results: in the PP+ V group, the Vicryl® mesh showed lower adhesion formation (p=0.013). In the PP+PC, there were no differences between polypropylene and Parietex composite® (p=0.765). In the PP+UP group, Ultrapro® and polypropylene meshes were equivalent (p=0.198). Conclusion: All the four meshes led to adhesions, with the Vicryl® mesh showing the least potential for its formation.
SUMMARY
A case of crossed ectopia of a solitary kidney is described. Some diagnostic and embryological aspects of the anomaly are discussed.
I am grateful to Mr Harland Rees for permission to report this case and for his helpful criticisms. I am also indebted to Miss F. Wadsworth for the drawings and to Mr R. Bartholomew for the photographs.
SUMMARY
A series of 104 cases of partial cystectomy for malignant tumours of the bladder has been reviewed. The results have been analysed in respect of the grade and the stage of the tumour, the anatomical site of the tumour, the width of tumour‐free margin excised, the presence or absence of local lymphatic invasion, and the value of post‐operative radiotherapy.
Perivesical extension of the tumour has been shown to be no contraindication to a partial cystectomy.
A one‐inch margin of normal bladder wall around the tumour has proved to be the most important single factor influencing prognosis.
The combination of surgery and radiotherapy appears to offer a better prospect of cure than either surgery alone or radiotherapy alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
