RESUMEN

We report the case of a gentleman referred with apparent worsening function in a hydronephrotic left-sided pelvic kidney. Imaging with Tc-99m-Mercaptoacetyltriglycine (MAG 3) in 1999, showed that the left kidney contributed 46% of renal function with no evidence of obstruction. Three years later, repeat scanning showed ectopic kidney function had decreased to 20% and with worsening pain, nephrectomy had been suggested. Review of the second MAG 3 scan revealed that only posterior images had been obtained. With pelvic kidneys, the pelvis forms a barrier between the radioactively labelled tracer and the gamma camera, thus, reducing the amount of radiation detected and underestimating function. A subsequent Dimercaptosuccinic acid scan (DMSA) was carried out with posterior and anterior images, the latter showing split renal function was identical to that seen on the initial scan. In patients with pelvic kidneys, anterior views must be obtained during radionuclide scanning if unnecessary nephrectomy is to be avoided.

RESUMEN

The lifespan of medical equipment must be maximised to ensure cost-effectiveness. Flexible ureterorenoscopes have become widely used in the diagnosis and treatment of urolithiasis. They are relatively expensive and current literature shows that they require frequent repair and replacement. We have analysed our data for the number of procedures and repairs required for each new instrument we have used. So far we have used four new flexible ureteroscopes, which have been used for a total of 375 procedures, an average of 94 procedures each. On average each required repair twice. We believe that a few simple precautions taken during use and storage help to maximise the lifespan of the flexible ureterorenoscope and our results would appear to support this.

RESUMEN

OBJECTIVE: To report our outcomes with small diameter, actively deflectable flexible ureterorenoscopy from a prospective database. PATIENTS AND METHODS: 114 flexible ureterorenoscopies were performed in 105 patients (mean age, 49.5 years; range, 19-85 years; 71 males, 34 females) over a 9-month period. Of these, 101 were for refractory stones following failed ESWL and 13 for diagnostic reasons. An Olympus URF P3 flexible ureteroscope with pressure irrigation was used. Electrohydraulic lithotripsy was used to fragment stones and the fragments were retrieved with Graspit, triradiate graspers or tipless baskets. RESULTS: Stents had previously been placed in 53% and dilatation of the ureteric orifice was necessary in 15%. In the stone group, the median operating time was 55 min (range, 15-210 min) and the median screening time 2.2 min (range, 0.3-9.1 min). Success was defined as complete stone clearance or good fragmentation to 2 mm or less. Overall success in this group was 72.3%. There was no statistically significant difference between lower and other calyces (P=0.83 Chi-square test). Successful outcome was achieved in 72% for stone size 10 mm or less, 80% for 11-20 mm and 50% for greater than 20 mm. Two or more procedures were needed in 8 patients. In the diagnostic group, the median operating time was 45 min (range, 20-60 min) and the median screening time 2 min (range, 0.3-8.3 min). The majority were for upper tract filling defects. Access and successful diagnosis was achieved in all cases. The major complication rate was 2.6%. The ureteroscope needed repair once during this series. CONCLUSIONS: Flexible ureterorenoscopy is an effective diagnostic and therapeutic tool in a select group of patients. It should be considered for ESWL-resistant upper tract stones but the results are poor in stones larger than 20 mm and percutaneous nephrolithotomy may be a better option in these patients.

RESUMEN

Elderly women are more likely to have less aggressive tumours, which are oestrogen receptor positive. They are less likely to be offered screening and often given inadequate treatment leading to a higher mortality rate. They should be assessed in the same way as their younger counterparts. Age should not be a consideration, rather life expectancy Patients' wishes are important but the mainstay of treatment is surgical, including axillary node clearance, with adjuvant tamoxifen as appropriate. Radiotherapy should not be withheld unless there are good reasons to contradict this. In unfit patients, tamoxifen alone is a suitable treatment but tumorectomy under local anaesthetic is preferable. If the tumour is oestrogen receptor negative, surgery and/or radiotherapy will be required.
