Mini-Photoselective Vaporization of the Prostate for Difficult Intermittent Self-Catheterization
Daniel Spernat,Henry Hyunshik Woo 대한비뇨의학회 2012 Investigative and Clinical Urology Vol.53 No.9
Bladder neck incision or transurethral incision of the prostate is a procedure described for men with bladder outflow obstruction associated with a gland size of less than 30 ml. We report a case of a man with detrusor dysfunction who was having increasing difficulty performing clean intermittent self-catheterization of the bladder. The successful use of the 120 W lithium triborate laser to perform a “mini-photoselective vaporization of the prostate” (“mini-PVP”) enabled discharge of the patient on the same day as well as resolution of the patient’s difficulties in performing self-catheterization. Mini-PVP has proven to be a simple and effective approach to resolution of a prostate configuration impeding the process of clean intermittent self-catheterization.

Background The aim of this study was to review the recipient vessels used in our cases of facial reanimation with free functional muscle transfer and to identify patient variables that may predict when the facial vessels are absent. From this we present a protocol for vessel selection in cases when the facial artery and/or vein are absent. Methods Patients were identified from November 2006 to October 2013. Data was collected on patient demographics, facial palsy aetiology, history of previous facial surgery/trauma and flap/recipient vessels used. A standard operative approach was adopted and performed by a single surgeon. Results Eighty-seven eligible patients were identified for inclusion amongst which 98 hemifaces were operated upon. The facial artery and vein were the most commonly used recipient vessels (90% and 83% of patients, respectively). Commonly used alternative vessels were the transverse facial vein and superficial temporal artery. Those with congenital facial palsy were significantly more likely to lack a suitable facial vein (P=0.03) and those with a history of previous facial surgery or trauma were significantly more likely to have an absent facial artery and vein (P<0.05). Conclusions Our algorithm can help to guide vessel selection cases of facial reanimation with free functional muscle transfer. Amongst patients with congenital facial palsy or in those with a previous history of facial surgery or trauma, the facial vessels are more likely to be absent and so the surgeon should then look towards the transverse facial vein and superficial temporal artery as alternative recipient structures.

<P>The rate of major galaxy-galaxy merging is theoretically predicted to steadily increase with redshift during the peak epoch of massive galaxy development (1 <= z <= 3). We use close-pair statistics to objectively study the incidence of massive galaxies (stellar M1 > 2 x 10(10)M(circle dot)) hosting major companions (1 <= M-1/M-2 <= 4; i.e. <4: 1) at six epochs spanning 0 < z < 3. We select companions from a nearly complete, mass-limited (>= 5 x 10(9)M(circle dot)) sample of 23 696 galaxies in the five Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey fields and the Sloan Digital Sky Survey. Using 5-50 kpc projected separation and close redshift proximity criteria, we find that the major companion fraction f(mc)(z) based on stellar mass-ratio (MR) selection increases from 6 per cent (z similar to 0) to 16 per cent (z similar to 0.8), then turns over at z similar to 1 and decreases to 7 per cent (z similar to 3). Instead, if we use a major F160W flux-ratio (FR) selection, we find that f(mc)(z) increases steadily until z similar to 3 owing to increasing contamination from minor (MR > 4: 1) companions at z > 1. We show that these evolutionary trends are statistically robust to changes in companion proximity. We find disagreements between published results are resolved when selection criteria are closely matched. If we compute merger rates using constant fraction-to-rate conversion factors (C-merg,C-pair = 0.6 and T-obs,T-pair = 0.65 Gyr), we find that MR rates disagree with theoretical predictions at z > 1.5. Instead, if we use an evolving T-obs,T-pair(z) alpha (1 + z)- 2 from Snyder et al., our MR-based rates agree with theory at 0 < z < 3. Our analysis underscores the need for detailed calibration of C-merg,C-pair and T-obs,T-pair as a function of redshift, mass, and companion selection criteria to better constrain the empirical major merger history.</P>

Purpose: To assess the diagnostic reliability of a dichotomous digital rectal examination (DRE) tool in assessing prostate volume (PV) compared to gold-standard transrectal ultrasound (TRUS) volume measurement.Materials and Methods: Male patients presenting to a single tertiary referral centre urology practice requiring TRUS were prospectively recruited between January 2010 and August 2011. Size was estimated by DRE immediately prior to TRUS measurement. DRE measurements were classed into four groups: <30 mL , 30 to 49 mL, 50 to 99 mL and >100 mL. The primary outcomes were sensitivity, specificity, and the positive and negative likelihood ratios for a 30 mL cut-off. Results: Three hundred and three patients were recruited to the study. The median age of the study group was 64.9 years. On TRUS analysis, 244 patients had a PV larger than 30 mL and 139 of them, larger than 50 mL. The median PV was 47 mL with a median International Prostate Symptom Score of 10 and prostatic specific antigen (PSA) of 5.7. When analysed for the ability to identify a gland larger than 30 mL, DRE had a high sensitivity and low negative likelihood ratio. The median PSA level (ng/L) for prostates measured by DRE with a 30 mL cut-off was significantly different with higher median PSA values for volumes larger than 30 mL. Conclusions: DRE is a reliable tool for dichotomous assessment of prostatic volumes above 30 mL and 50 mL. These results illustrate the value of re-examining the role of categorical DRE estimations in benign prostatic hyperplasia patients.

Objective: The purpose of this study was to evaluate the influence of body condition score (BCS) at calving on the metabolic status of female Murrah buffaloes in the transition period. Methods: Thirty-seven pregnant buffaloes (multiparous) were selected and monitored during the transition period based on their body condition score and on the estimated calving date. Two groups were formed: i) buffaloes with a BCS>3.5 (n = 17); this group was classified and named ‘high BCS at calving’ (HBCS); and ii) buffaloes with a BCS≤3.5 (n = 20); this group was classified and named ‘low BCS at calving’ (LBCS). All animals were monitored during the last 30 days of pregnancy and the first 70 days post-calving and kept in the same environment and under the same feeding and management conditions. Mean values for BCS at calving were 2.98±0.9 (mean±standard error of the mean [SEM]) and 4.21±0.9 (mean±SEM) for the HBCS and LBCS groups, respectively. Results: The HBCS group showed higher milk fat content (p = 0.007) and milk fat yield (p = 0.027) and a higher concentration of milk urea nitrogen (p = 0.001) than LBCS buffaloes, which in turn had a lower urine pH value (p = 0.033) than HBCS buffaloes in the pre-calving period (7.86 for HBCS vs 7.76 for LBCS). The HBCS animals had a higher concentration of erythrocytes (p = 0.001) and hematocrit (p = 0.012) post-calving and a higher hemoglobin concentration (p = 0.004) pre-calving. Conclusion: Buffaloes during the transition period exhibited some variations in the oxidative stress related to their metabolic status. After calving, buffaloes with a high BCS at calving and greater lipid mobilization have a more marked alteration in oxidative status, but improved production performance.
