Cystectomy is surgery to remove your bladder. This is usually done to control bladder cancer. Depending on the extent of the cancer, the bladder and some surrounding organs may need to be removed. • The prostate gland, seminal vesicles and nerve bundles may also be removed. • The ovaries, fallopian tubes, uterus, cervix and part of the vagina may also be removed.

However, their use after nephrectomy has raised concerns regarding possible nephrotoxicity. This study compared postoperative renal function and postoperative outcomes between patients using NSAID and patients using opioids for PCA in nephrectomy. In this retrospective observational study, records were reviewed for 913 patients who underwent laparoscopic or robot-assisted laparoscopic nephrectomy from 2015 to 2017. After propensity score matching, 247 patients per group were analyzed. Glomerular filtration rate (GFR) percentages (postoperative value divided by preoperative value), blood urea nitrogen (BUN)/creatinine ratios, and serum creatinine percentages were compared at 2 weeks, 6 months, and 1 year after surgery between users of NSAID and users of opioids for PCA.

  • Continent Urinary Reservoirs and Bladder Substitutes.Pdf
    ������������������ ��������������� ������������������� �������������������� ���������������� ��������������������� Continent Cutaneous Urinary Reservoirs and Bladder Substitutes Anatomy The bladder is an organ in the pelvis that collects, stores and expels urine. Urine is produced by the kidneys and travels down two tube-like structures called the ureters. The ureters connect the kidneys to the bladder. Urine leaves the bladder through another tube-like structure called the urethra. (Figure 1) Removal of the bladder (cystectomy) may be necessary in some people with bladder cancer, congenital disor- ders of the urinary tract, and in some people who have suffered surgical, traumatic or neurologic damage to the bladder. In these situations, another method of col- lecting and excreting urine must be found. The most common and easiest method for urinary diversion is to use a short piece of intestine as the connection between the ureters and the outside of the body (ileal or colon conduit). This type of diversion is easy for the patient to manage and has a low rate of complication. However, an ostomy bag must be worn at all times to collect urine. Newer surgical techniques are available which do not require the patient to wear an ostomy bag. These newer proce- dures involve creation of a continent urinary reser- voir that collects and stores urine. What is a Continent Urinary Reservoir and How is it Made? A continent urinary reser- voir is an internal “pouch” made from segments of the intestine. Urinary reservoirs can be made from small intestine alone, large intestine alone or from a combination of the above. (Figure 2) The bowel segments selected for use are disconnected from the remainder of the intestinal tract to avoid mixing the gastrointestinal contents (feces) with urine.

  • Dr. Alexander Kutikov: Yeah
    Question and Answer Stephanie Chisolm: I deeply thank you so much. Dr. Kutikov, that was phenomenal and I think you really did such a great job of explaining all of those complications and everything else. I think the underlying message that I heard, and I hope that the participants here is kind of you wouldn't take your Jaguar to the mechanic on the corner. You go to somebody that does this on a regular basis. You really want to go to somebody who has that experience if you're going to have the surgery, because it is complicated. You don't want them to say, "I read about that in a journal once." Then, "Sure, I can do that. I'm a doctor." You want to go with somebody who has an awareness of what the problems are so you can circumvent them certainly. I think that that came through very closely and very clearly. Let's get to some of the questions. We have a kind of a unique question. There's a participant with only one kidney and their GFR is holding at 27. I guess they're indicating that they're going to have a cystectomy. If they choose to have the stoma and need dialysis, I think this is a good recommendation in terms of getting in the team approach. Because dialysis can be run by the nephrologist, correct? Is it possible to do dialysis when you only have a stoma? Dr. Alexander Kutikov: Yeah. Hemodialysis, the stoma won't affect your hemodialysis. I think the question is asking whether they can do peritoneal dialysis, which is basically putting dialysis fluid in the belly and having an exchange and do what a kidney does, but filter the toxins through the peritoneum.

  • The Morbidity Due to Lower Urinary Tract Function in Spinal Cord Injury Patients
    Paraplegia 31 (1993) 320-329 © 1993 International Medical Society of Paraplegia The morbidity due to lower urinary tract function in spinal cord injury patients P E V Van Kerrebroeck MD PhD, E L Koldewijn MD, S Scherpcnhuizen, F M J Debruyne MD PhD Department of Urology, Unit for Neurourology and Urodynamics, University Hospital St Radboud, Geert Grooteplein Zuid 16, PO Box 9101, NL-6500 HB Nijmegen, The Netherlands. A review is given of 105 patients with a traumatic spinal cord injury. In 93 patients with a minimum follow up of one year the morbidity due to lower urinary tract function was evaluated, based on the situation at their last control visit. The relation was studied between bladder behaviour and the type of urine evacuation and their influence on upper urinary tract problems, urinary tract infections, stone formation and incontinence. Based on the results of this study the most appropriate method for control of bladder behaviour and urine evacuation in spinal cord injured patients is discussed in view of new treatment modalities such as dorsal rhizotomies and the implantation of an anterior sacral root stimulator.

    Narita et al. BMC Urology (2017) 17:72 DOI 10.1186/s12894-017-0263-x RESEARCH ARTICLE Open Access Presence of transient hydronephrosis immediately after surgery has a limited influence on renal function 1 year after ileal neobladder construction Takuma Narita1, Shingo Hatakeyama1* , Takuya Koie1, Shogo Hosogoe1, Teppei Matsumoto1, Osamu Soma1, Hayato Yamamoto1, Tohru Yoneyama2, Yuki Tobisawa1, Takahiro Yoneyama1, Yasuhiro Hashimoto2 and Chikara Ohyama1,2 Abstract Background: Urinary tract obstruction and postoperative hydronephrosis are risk factor for renal function deterioration after orthotopic ileal neobladder construction. However, reports of relationship between transient hydronephrosis and renal function are limited. We assess the influence of postoperative transient hydronephrosis on renal function in patients with orthotopic ileal neobladder construction. Methods: Between January 2006 and June 2013, we performed radical cystectomy in 164 patients, and 101 received orthotopic ileal neobladder construction. This study included data available from 64 patients with 128 renal units who were enrolled retrospectively. The hydronephrosis grade of each renal unit scored 0–4. The patients were divided into 4 groups according to the grade of hydronephrosis: control, low, intermediate, and high. The grade of postoperative hydronephrosis was compared with renal function 1 month and 1 year after surgery. Results: There were no significant differences in renal function before surgery between groups. One month after surgery, the presence of hydronephrosis was significantly associated with decreased renal function. However, 1 year after urinary diversion hydronephrosis grades were improved significantly, and renal function was comparable between groups. Postoperative hydronephrosis at 1 month had no significant influence on renal function 1 year after ileal neobladder construction.
