Metabolic syndrome and sexual (dys)function.

INTRODUCTION: The general worldwide increase in metabolic syndrome (MS) among most populations may result in more individuals with sexual dysfunction. AIM: To provide an update on clinical and experimental evidence regarding sexual dysfunction in patients with MS from both sexes and treatment modalities. METHODS: A comprehensive literature review was performed using MEDLINE with the MeSH terms and keywords for "metabolic syndrome,""obesity,""female sexual dysfunction,""erectile dysfunction,""androgen deficiency,""weight loss," and "bariatric surgery." MAIN OUTCOME MEASURES: To examine the data relating to sexual function in both men and women with MS, its relationship and the impact of treatment. RESULTS: The MS is strongly correlated with erectile dysfunction, hypogonadism (predictors of future development of MS), and female sexual dysfunction. Few studies have been addressed in the treatment of these dysfunctions in the special setting of MS, other than the observational effects on sexual function of individual risk factors correction. This can be a result of their understudied etiopathogeny. Nonsurgical weight loss has been shown to improve sexual function (with the mainstay on sedentarism prevention), whereas the efficacy of bariatric surgery in this respect, which has been suggested by some preliminary evidence, needs to be further confirmed by adequate clinical trials. CONCLUSION: As the global incidence of MS increases, more individuals may experience sexual dysfunction and a systematic evaluation should be emphasized in this patient population, in order to identify those who are in need of intervention.

Coagulum pyelolithotomy "revisited" by laparoscopy: technique modification.

OBJECTIVE: Laparoscopic ureteropyeloplasty is a widely accepted treatment option for the obstructed ureteropelvic junction (UPJ). Although it is often a straightforward surgical procedure, there may be technical difficulties in the case of concomitant stone burden, with multiple calicial, small, mobile stones. The authors describe a modification to the classic coagulum pyelolitothomy, using a mixture based on commercially available fibrin sealant, first used in the laparoscopic era. METHODS: During a laparoscopic transperitoneal dismembered ureteropyeloplasty complemented with coagulum pyelolithotomy, the following steps are suggested: (1) Exposure of the UPJ; (2) ureter clamping with a vessel loop 2 cm distal to the UPJ (to allow pelvis filling); (3) transabdominal puncture of the pelvis with an 18-G, 20-cm needle (under laparoscopic vision) and urine aspiration; (4) recording the volume of urine aspirated; (5) preparing an equal volume of fibrin sealant (to avoid overdistention of the pelvis); (6) injecting the sealer protein solution through that needle + 1 mL of methylene blue (color the coagulum and facilitate its identification in the removal procedure); (7) insertion of another needle to inject the thrombin solution; (8) wait 5 minutes to allow coagulum cast formation; (9) circumferential excision of the UPJ; (10) coagulum removal; (11) pelvis plastic reduction (if needed) and ureter spatulation; (12) double-J stent placement; and (13) tension-free anastomosis completion. RESULTS: The procedure results in the extraction of a tenacious coagulum containing more stones than normally anticipated from the x-ray studies. CONCLUSIONS: This technique modification reduces the incidence of incomplete stone removal, when there are small, free stones lying in a large renal pelvis.
