Imaging protocols for renal multiparametric MRI and MR urography: results of a consensus conference from the French Society of Genitourinary Imaging.

Objectives: To develop technical guidelines for magnetic resonance imaging aimed at characterising renal masses (multiparametric magnetic resonance imaging, mpMRI) and at imaging the bladder and upper urinary tract (magnetic resonance urography, MRU).

Methods: The French Society of Genitourinary Imaging organised a Delphi consensus conference with a two-round Delphi survey followed by a face-to-face meeting. Two separate questionnaires were issued for renal mpMRI and for MRU.

[Imaging of pelvic organ prolapse].

Colpocystodefecography (CCD) and dynamic MRI with defecography (MRId) allow an alternation between filling and emptying the hollow organs and the maximum abdominal strain offered by the defecation. When applied in imaging these two principles reveal the masked or underestimated prolapses at the time of the physical examination. A rigorous application of the technique guarantees almost equivalent results from the two examinations.

[Recommendations for imaging in the investigation of non-neurological female urinary incontinence].

INDICATIONS FOR IMAGING: Apart from ultrasound assessment of post-voiding residual urine, radiological examinations are not recommended for the initial work-up of non-neurological female urinary incontinence. CYSTOGRAPHY: Cystography is not recommended as a first-line examination to evaluate uncomplicated stress, urge or mixed urinary incontinence. Cystography may be recommended in the case of complex, complicated or relapsing urinary incontinence, discordance between clinical findings and urodynamic assessment or in the presence of associated prolapse, in which case colpocystodefecography or even dynamic MRI should be preferred.

Relation between the anatomical genital phenotype and cystic fibrosis transmembrane conductance regulator gene mutations in the absence of the vas deferens.

Objective: To study the correlation between genital phenotype and cystic fibrosis genotype in men lacking at least one vas deferens.

Design: Prospective study.

Setting: Institut Rhônalpin pour la Reproduction Humaine, Lyon-Bron, France.
