Safety and feasibility of concomitant surgery during holmium laser enucleation of the prostate (HoLEP)

Purpose

To determine the feasibility and outcomes associated with performing simultaneous surgical procedures during holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia and concomitant urologic conditions.

Methods

A retrospective review of patients that underwent a HoLEP was performed. Patients undergoing a concomitant procedure at the time of HoLEP were selected and stratified based on complexity of the secondary procedure (simple, intermediate, and complex) and matched based on age and prostate volume to patients undergoing only a HoLEP. Baseline characteristics, preoperative, operative, and postoperative outcomes were collected.

Results

A total of 372 HoLEPs were performed. Thirty-eight (10.2 %) patients underwent concomitant procedures at the time of HoLEP. Compared to the simple and intermediate secondary surgical procedures, the matched control group that underwent a HoLEP alone did not demonstrate statistically significant differences in the preoperative, operative, or postoperative outcomes. Patients with a complex secondary surgical procedure at the time of HoLEP had statistically significant differences in operative time (221 vs. 65 min, p = 0.007), estimated blood loss (92 vs. 33 mL, p = 0.012), catheter time (8.5 vs. 1 day, p = 0.041), and length of hospitalization (2 vs. 1 day, p = 0.032) compared to the control group.

Conclusions

Obstructive voiding symptoms secondary to BPH are common in older patients and may coincide with other concomitant lower urinary tract pathology that may require surgical intervention. Rather than staging surgical interventions, it appears that definitive treatment for BPH with HoLEP is safe and efficacious in those patients that also require secondary procedures.     

A clinical profile of patients with Parkinson's disease and psychosis

Aims:

The aim of the study was to study the clinical profile of the patients with Parkinson''s disease (PD) and psychosis.

Settings and Design:

This was a prospective, cross sectional, hospital-based study done at the Department of Neurology, National Institute of Mental Health and Neurosciences, Bangalore, India from September 2009 to January 2011. All patients with PD, diagnosed by United Kingdom PD Society Brain Bank criteria, having with features of psychosis as diagnosed by the neuropsychiatric inventory (NPI) were included. Patients without a caregiver who could validate the patient''s symptoms were excluded.

Results:

A total of 40 patients (5 women, 35 men) with PD with psychosis (mean age: 54.2 ± 11.5 years, mean duration of illness: 6.5 ± 4.5 years, and mean duration of psychosis: 4.3 ± 4.3 years) were included in the study. The Global NPI score was 19.1 ± 11.5. Majority of the patients had pure hallucinations (85%), while the rest had either pure delusions (7.5%) or a combination of delusions and hallucinations (7.5%). In those with hallucinations, visual hallucinations were the commonest (60%) (pure only in 22.5%), followed by auditory (45%), minor hallucinations (45%), and tactile (20%). Only one person reported having olfactory hallucinations (2.5%). Loss of insight was most often observed during the visual hallucinations (52%), followed by tactile (44.4%), auditory (38.9 %), and minor hallucinations (33.3%).

Conclusions:

In patients with PD and psychosis, pure hallucinations are common and visual hallucinations are the commonest among the hallucinations. A large proportion of patients have minor hallucinations, which need to be recognized early for effective and early management. The limitations of the study were small sample size, use of a single scale to assess psychosis and subjective assessment of insight.     

Improvement in renal function following cryoballoon ablation for atrial fibrillation

Purpose

Patients with chronic kidney disease are predisposed to heart rhythm disorders including atrial fibrillation (AF). Several studies have suggested that radiofrequency catheter ablation of AF improves renal function. However, little data exists for pulmonary vein isolation with cryoballoon ablation (CBA). The purpose of this study is to assess change in renal function following CBA for AF.

Method

This is a single-center retrospective study that included patients who underwent CBA for AF between 2011 and 2016. Patients were grouped by baseline-estimated glomerular filtration rate (eGFR): ≥?90 (Stage G1), 60–89.9 (Stage G2), and 30–59.9 mL/min/1.73 m² (Stage G3). Change in eGFR was assessed >?3 months post-ablation.

Results

A total of 306 patients with both pre- and post-ablation serum creatinine measurements available were included. Baseline eGFRs for Stages G1, G2, and G3 patients were 103.5?±?12.9 (n?=?82), 74.7?±?8.2 (n?=?184), and 52.6?±?6.6 mL/min/1.73 m² (n?=?40), respectively. Renal function was assessed 310.8?±?104.2 days post-ablation. Average intra-procedural contrast use was 58.4?±?23.8 mL. There was no significant change in eGFR following CBA in Stage G1 patients (p?=?0.10). For those with Stages G2 and G3 renal function, eGFR improved by 6.1% (4.2 mL/min/1.73 m², p?<?0.01) and 13.8% (7.2 mL/min/1.73 m², p?<?0.01), respectively. This improvement was seen regardless of the presence or absence of recurrent atrial arrhythmias.

Conclusions

CBA for AF may be associated with an improvement in renal function, particularly among those with a reduced baseline eGFR despite recurrence of atrial arrhythmias and intra-procedural contrast use.
